Demyelinating diseases are a type of neurological disorder characterized by the damage to the myelin sheath in the central nervous system. Promoting the proliferation and differentiation of oligodendrocyte precursor cells (OPCs) is crucial for treatment. Non-selective muscarinic receptor (MR) antagonists have been shown to improve remyelination in rodent models, although the mechanisms are still unclear. In this study, we treated cuprizone (CPZ)-induced demyelination mouse model with different concentrations of Solifenacin (Sol), a selective M3 receptor antagonist, to determine the optimal concentration for promoting remyelination. Behavioral tests and Luxol fast blue (LFB) staining were used to observe the extent of remyelination, while immunofluorescence was used to measure the expression levels of myelin-related proteins, including myelin basic protein (MBP) and platelet-derived growth factor receptor alpha (PDGFR-α). Western blot analysis was employed to analyze the expression levels of molecules associated with the Wnt/β-catenin signaling pathway. The results showed that Sol treatment significantly promoted myelin regeneration and OPCs differentiation in CPZ-induced demyelination mouse model. Additionally, Sol treatment inhibited the Wnt/β-catenin signaling pathway and reversed the effects of CPZ on OPCs differentiation. In conclusion, Sol may promote the differentiation of OPCs by inhibiting the Wnt/β-catenin signaling pathway, making it a potential therapeutic option for central nervous system demyelinating diseases., Competing Interests: Declaration of Competing Interest The authors confirm that there are no conflicts., (Copyright © 2023 Elsevier B.V.

bladder based on a systematic review and network meta-analysis approach., Methods: Pubmed, Embase, Web of Science, and the Cochrane Register of Clinical Trials databases were systematically searched. The search time frame was from database creation to June 2, 2022. Randomized controlled double-blind trials of oral medication for overactive bladder were screened against the protocol's entry criteria. Trials were evaluated for quality using the Cochrane Risk of Bias Assessment Tool, and data were statistically analyzed using Stata 16.0 software., Result: A total of 60 randomized controlled double-blind clinical trials were included involving 50,333 subjects. Solifenacin 10mg was the most effective in mean daily micturitions and incontinence episodes, solifenacin 5/10mg in mean daily urinary urgency episodes and nocturia episodes, fesoterodine 8mg in urgency incontinence episodes/d and oxybutynin 5mg in voided volume/micturition. In terms of safety, solifenacin 5mg, ER-tolterodine 4mg, mirabegron, vibegron and ER-oxybutynin 10mg all showed a better incidence of dry mouth, fesoterodine 4mg, ER-oxybutynin 10mg, tolterodine 2mg, and vibegron in the incidence of constipation. Compared to placebo, imidafenacin 0.1mg showed a significantly increased incidence in hypertension, solifenacin 10mg in urinary tract infection, fesoterodine 4/8mg and darifenacin 15mg in headache., Conclusion: Solifenacin showed better efficacy. For safety, most anticholinergic drugs were more likely to cause dry mouth and constipation, lower doses were better tolerated. The choice of drugs should be tailored to the patient's specific situation to find the best balance between efficacy and safety., Competing Interests: None declared., (Copyright® by the International Brazilian Journal of Urology.)

Objectives: This study investigates the efficacy and adverse events of beta-3 agonists and antimuscarinic agents for managing overactive bladder syndrome in Sjogren syndrome., Methods: Sjogren's syndrome patients with an Overactive Bladder Symptom Score (OABSS) >5 were enrolled and were randomly assigned to mirabegron 50 mg/day or solifenacin 5 mg/day. Patients were evaluated on the recruitment day and reassessed at Week 1, 2, 4, and 12. The study's primary endpoint was to have a significant change in OABSS at Week 12. The secondary endpoint was the adverse event and crossover rate., Results: A total of 41 patients were included in the final analysis, with 24 in the mirabegron group and 17 in the solifenacin group. The study's primary outcome was a change of the OABSS at Week 12. We found that both mirabegron and solifenacin significantly reduce patients' OABSS after 12 weeks of treatment. The evolution of the OABSS was -3.08 for mirabegron and -3.71 for solifenacin (p = .56). Six out of 17 patients from the solifenacin group crossed over to the mirabegron arm due to severe dry mouth or constipation, while none from the mirabegron arm crossed over to the solifenacin group. Sjogren's syndrome-related pain was also improved in the mirabegron group (4.96-1.67, p = .008) compared to the solifenacin group (4.39-3.4, p = .49)., Conclusions: Our study showed that mirabegron is equally effective as solifenacin in treating Sjogren's syndrome patients with overactive bladder. Mirabegron is superior to solifenacin in terms of treatment-related adverse events., (© 2023 John Wiley & Sons Australia, Ltd.)

Background: Overactive bladder is mostly treated with a combination of behavioural interventions and commonly prescribed anti-muscarinic medication therapy, including solifenacin, which has considerable side effects and lowers the quality of life. Mirabegron relaxes the detrusor muscle and is a recently approved drug for the treatment of OAB. This study examined the effectiveness and safety of two medications, solifenacin and mirabegron., Methods: This study was a comparative cross-sectional study conducted at Sami Medical Center, Abbottabad for a period of 6 months from August 2022 to January 2023. Female patients of aged ≥18 years with symptoms of OAB were enrolled., Results: Current study showed that the average age of patients was 37.47±12.48 years in Group S and 39.93±7.93 in Group M. The population consists of 60 (100%) females. After 4 weeks of follow up dizziness, dry mouth, constipation hypertension and blurred vision were found insignificant between both groups with p-values of 0.312, 0.161, 0.076, 0.076, and 0.313 respectively. OABSS score improved significantly and after therapy 4.20±1.32 in Group S and 3.43±1.13 in Group M. There was no significant difference in frequency of treatment withdrawal p-value 0.150., Conclusions: When it comes to relieving symptoms of OAB, both solifenacin and mirabegron are effective. The OABSS improved with both drugs; however, mirabegron was associated with fewer treatment-related adverse events. We advocate using mirabegron as the first-line treatment. Solifenacin can be utilized if patients are no longer getting the desired effects from Mirabegron.

Background: Solifenacin is an anticholinergic that is used to treat overactive bladder syndrome (OAB) in children. It is important to ascertain the safety and tolerability of solifenacin in the paediatric population as solifenacin offers an alternative, is more bladder specific, and should have less anticholinergic side effects than other therapies., Objective: The aim of this study is to systematically evaluate the safety and tolerability of solifenacin in children and adolescents with OAB., Study Design: We included studies that reported the safety and tolerability of solifenacin in children and adolescents. All study types were included. Electronic searches were conducted in Ovid MEDLINE, Ovid Embase, TRIP, CINAHL and ICTRP on the 18th of January 2022. Risk of bias was assessed with the Cochrane Risk of Bias tool 2.0 (ROB-2) for randomised controlled trials (RCTs) and the Newcastle-Ottowa scale for cohort studies., Results: A total of twelve studies including two RCTs were included in this review. Results from the meta-analysis of RCTs showed the commonest side effects were constipation (RR 3.5, 95%CI 0.9-13.7) and dry mouth (RR 3.1 95%CI 0.2-53). In terms of tolerability, the effect estimate of ceasing solifenacin due to an adverse effect was 2.7 (95%CI 0.8-9.1). Within the cohort studies, out of the 779 patients 21.7% experienced side effects. The most common side effects were constipation (6.8%) and dry mouth/lips (6.0%) and 3.5% of patients ceased solifenacin due to adverse effects. Overall, the certainty of the evidence for side effects and tolerability were very low., Discussion: The reported incidence of side effects is low, and less than reported with oxybutynin use. However, the very low certainty of the evidence means the findings should be interpreted with caution. There is limited reporting of a prolonged QTc interval on ECG. Studies that described this only had an increase of QTc from baseline and not a clinically significant prolonged QTc that resulted in arrhythmias., Conclusion: Solifenacin is an alternative anticholinergic for the treatment of OAB in children. However, given the paucity of good quality data on safety and tolerability it should be used cautiously in children with close monitoring for potential side effects., (Crown Copyright © 2022.

Background: Antimuscarinics are the backbone of the pharmacological management of overactive bladder. Still, concerns have been raised over the nervous system (NS) adverse drug events (AEs) due to their dissimilarities to muscarinic receptor-subtype affinities., Objective: This study aimed to identify the nervous system and gastrointestinal adverse drug events (ADEs) associated with solifenacin use in older adults (≥65 years)., Methods: A case/non-case analysis was performed on the reports submitted to the FDA Adverse Event Reporting System (FAERS) between 01/01/2004 and 30/06/2020. Cases were reports for solifenacin with ≥1 ADEs as preferred terms included in the Medical Dictionary of Regulatory Activities (MedDRA) system organ classes 'nervous system' or 'gastrointestinal' disorders. Non-cases were all other remaining reports for solifenacin. The case/non-cases was compared between solifenacin and other bladder antimuscarinics. Frequentist approaches, including the proportional reporting ratio (PRR) and reporting odds ratio (ROR), were used to measure disproportionality. The empirical Bayesian Geometric Mean (EBGM) score and information component (IC) value were calculated using a Bayesian approach. A signal was defined as the lower limit of 95% confidence intervals of ROR ≥ 2, PRR ≥ 2, IC > 0, EBGM > 1, for ADEs with ≥4 reports., Results: 107 MedDRA preferred terms (PTs) comprising 970 ADE reports were retrieved for nervous system disorders associated with solifenacin. For gastrointestinal disorders, 129 MedDRA PTs comprising 1817 ADE reports were retrieved. Statistically significant results were found for 'altered state of consciousness': ROR = 9.71 (2.13-44.35), PRR = 9.69 (2.12-44.2) and IC = 1.29 (0.93-1.66)., Conclusions: The disproportionality reporting of 'altered state of consciousness', a previously unidentified ADE, was unexpected. Further monitoring of this ADE is needed to ensure patient safety, as this could be linked to poor balance and falls in older adults.

Background: Antimuscarinic (AM) and beta-3-agonist (B3A) treatment are the standard first-line pharmacological treatment used to manage overactive bladder (OAB) patients. Aim of our study was to analyze real-life data of adverse events related to AMs and B3A reported on Eudra-Vigilance (EV) Database., Methods: EV database is the system for managing and analyzing information on suspected adverse reactions to medicines which have been authorized or being studied in clinical trials in the European Economic Area (EEA). We recorded the number of AEs for antimuscarinic and beta-3-agonist per category and severity until January 2021., Results: Overall, 2313 AEs were reported for oxybutinin, 5129 for solifenacin, 2483 for tolterodine, 3523 for fesoterodine, 787 for trospium, 621 for propiverine and 7213 for mirabegron. Urinary retention was higher for fesoterodine (43%) and tolterodine (23%) when compared to solifenacin (10%), mirabegron (11%) and oxybutinin (4%). Cognitive disorder was uncommon for all the analyzed drugs analyzed. Regarding anticolinergic AEs: vision blurred, dry mouth and constipation were higher for AMs when compared to mirabegron. Their prevalence was higher in female patients. Mirabegron presented a higher risk of hypertension (7%) when compared to oxybutinin (2%, P<0.01), solifenacin (2%, P<0.01), tolterodine (2%, P<0.01) and fesoterodine (1%, P<0.01); the rate of hypertension was higher in females (63%) than males (29%) (P<0.01). The risk of acute urinary retention was also significantly higher (15% vs. 10%, P<0.01) in older patients (>85 years)., Conclusions: Real life data is consistent with registry studies regarding the rate of AEs related to antimuscarinic and beta-3-agonist. However some differences were observed. Female patients present higher rates of AEs when compared to male patients. The risk of acute urinary retention was particularly evident in the octogenarians.

To observe the efficacy and safety of solifenacin and/or mirabegron as a medical expulsive therapy (MET) in patients with double-J stent-related overactive bladder (OAB) symptoms. A total of 219 patients with double-J stent-related OAB symptoms were prospectively randomized into two groups. One-hundred and nine cases in the combination group accepted mirabegron and solifenacin therapy and 110 cases as control only accepted solifenacin therapy. The lower urinary tract symptoms and overactive bladder questionnaire (OAB-q) health-related quality of life (HRQol) and symptom bother score between two groups were compared at the 1st, 2nd and 4th week ends. All of 219 patients were randomly assigned to two groups, of which 109 patients were included in the combination group and 110 in the solifenacin group. The incidences of LUTS, including urgency, frequent urination, and incontinence episodes, in the 2nd week (44.9% vs. 64.5%, P = 0.028; 48.6% vs. 62.7%, P = 0.036; and 40.4% vs. 56.4%, P = 0.018) and the 4th week (14.7% vs. 30.9%, P = 0.004; 16.5% vs. 33.6%, P = 0.003; and 11.9% vs. 26.4%, P = 0.007) after combination treatment were significantly lower than those in the solifenacin group. The incidence of drug-related adverse events in the solifenacin group was higher than that in the combination group, but there was no statistically significant difference (P > 0.05). In terms of secondary variables, the OAB-q HRQol score in the combination group was statistically superior in comparison with that in the solifenacin group between the second and fourth week (77.9 vs. 76.4, P = 0.020; and 87.9 vs. 85.6, P = 0.001). The OAB-q symptom bother score was higher in the solifenacin group than in the combination group (37.6 vs. 36.4, P = 0.016; and 26.2 vs. 24.8, P = 0.003). Combination therapy of solifenacin and mirabegron demonstrated significant improvements over solifenacin monotherapy in reducing OAB symptoms associated with double-J stents, and providing a higher quality of life without increasing bothersome adverse effects., (© 2022.

Purpose: This cohort study evaluates therapeutic efficacy and adverse events (AEs) of various overactive bladder (OAB) medications for patients with central nervous system (CNS) disorders., Methods: Patients with OAB and CNS disorders were prospectively enrolled. They were randomly allocated to 3 different treatment subgroups: (1) mirabegron 50 mg once daily (2) solifenacin 5 mg per day, and (3) combined solifenacin 5 mg and mirabegron 50 mg once daily. Efficacy and safety questionnaires and objective parameters were compared among the subgroups, and subgroups between baseline and 3 and 6 months after treatment. AEs, including cognitive dysfunction, were assessed using the Mini-Mental State Examination (MMSE)., Results: 102 patients (mean age, 71.8 ± 8.7 years) were enrolled, including 35, 36, and 31 patients received mirabegron monotherapy, solifenacin monotherapy, and combination therapy, respectively. OAB symptoms scores all significantly improved 3 months after treatment in different subgroup. However, PVR increased and VE decreased significantly after treatment in patients receiving solifenacin monotherapy and combination therapy. Dry mouth and constipation were the most common AEs, especially in the solifenacin and combination subgroups. Mild incidence of AEs was noted in patients receiving mirabegron monotherapy. No significant change in MMSE was noted among the subgroups after treatment., Conclusion: OAB medication had good therapeutic efficacy in patients who had OAB with CNS disorders, especially in cerebrovascular accident and parkinsonism. No OAB medication or their combination affected cognitive function, whereas minimal AEs were noted with mirabegron. Mirabegron could be recommended as the first choice for managing OAB in these patients., Competing Interests: Declaration of competing interest The authors have no conflicts of interest relevant to this article., (Copyright © 2022 Formosan Medical Association.

Background: The differential risk of incident dementia associated with receiving various overactive bladder (OAB) drugs is unknown., Objective: To estimate the association of antimuscarinic OAB drug (exposure), compared with a β-3 agonist (mirabegron), and incident dementia., Design, Setting, and Participants: A population-based nested case-control study was conducted in patients treated with OAB medications in Ontario, Canada. A total of 11 392 patients aged ≥66 yr with a new diagnosis of dementia between 2010 and 2017, and 29 881 age- and sex-matched controls without dementia were included in the study., Intervention: Receipt of an antimuscarinic OAB drug or receipt of mirabegron, within the previous 6-12 mo., Outcome Measurements and Statistical Analysis: Cases developed dementia and Alzheimer's disease. Controls were derived from the general population and matched to cases based on important baseline characteristics. Odds ratios (ORs) for incident dementia, adjusted for demographic and health-related characteristics, were determined., Results and Limitations: Patients receiving solifenacin (OR 1.24; 95% confidence interval 1.08-1.43) and darifenacin (OR 1.30; 95% CI 1.08-1.56) in the prior 6 mo had increased odds of incident dementia compared with those receiving mirabegron. In the 6 mo to 1 yr prior to diagnosis, receipt of solifenacin (OR 1.34; 95% CI 1.11-1.60), darifenacin (OR 1.49; 95% CI 1.19-1.86), tolterodine (OR 1.21; 95% CI 1.02-1.45), and fesoterodine (OR 1.39; 95% CI 1.14-1.71) was associated with increased odds of incident dementia compared with receipt of mirabegron. No effect was seen with oxybutynin or trospium. Limitations included misclassification of the outcome and residual confounding associated with the use of health administrative databases., Conclusions: Older adults receiving solifenacin and darifenacin in the 6 mo prior to diagnosis, and those receiving solifenacin, darifenacin, tolterodine, or fesoterodine in the year prior to diagnosis, have increased odds of incident dementia, compared with those receiving mirabegron. Oxybutynin and trospium were not associated with dementia, likely due to a protopathic bias. Careful drug selection is warranted when treating patients with OAB., Patient Summary: In a large Canadian cohort of patients who developed dementia after starting an overactive bladder (OAB) medication, those taking some anticholinergic medications for OAB have an increased risk of dementia compared with those taking mirabegron., (Copyright © 2021 European Association of Urology.

Background: Older adults are at an increased risk of delirium because of age, polypharmacy, multiple comorbidities and acute illness. Antimuscarinics are the backbone of the pharmacological management of overactive bladder. However, the safety profiles of antimuscarinics vary because of their dissimilarities to muscarinic receptor-subtype affinities and are associated with differential central anticholinergic adverse effects., Objective: This study aimed to examine delirium risk in new users of oxybutynin and solifenacin in older adults (≥ 65 years). In the secondary analyses, we examined the risk of delirium by type and dose of antimuscarinic., Method: We applied a case-time-control design to investigate delirium risk in older adults who started taking oxybutynin and solifenacin. We used a nationwide inpatient hospital data (2005-2016), National Minimum Data Set, maintained by the Ministry of Health, New Zealand (NZ), to identify older adults with a new-onset diagnosis of delirium. Eligible patients were older adults aged 65 at entry into the cohort on 1/1/2006. We used dispensing claims data to determine antimuscarinic treatment exposure. The antimuscarinic included in the study were new users of oxybutynin and solifenacin. These two antimuscarinics are subsidised by the Pharmaceutical Management Agency and are the most frequently used antimuscarinic in NZ. A conditional logistic regression model was used to compute matched odds ratios (MORs) and 95% confidence intervals (CIs). In the case-time-control design, we made separate analyses to evaluate the dose-response risk of delirium., Results: We identified 4818 individuals (mean age 82.14) from 2005 to 2015 with incident delirium and were exposed to at least one of the antimuscarinic of interest. The case-time-control matched odds ratio (MOR) for delirium with oxybutynin was (2.06, 95% confidence interval [CI] 1.07-3.96). Solifenacin was not associated with delirium (0.89 95%CI 0.64-1.23). In the sensitivity analyses, the case-time-control MOR for delirium using a shorter risk period (0-3 days) did not change the results. The dose-response risk of delirium was significant for oxybutynin (0.05, 95%CI 0.02-0.08) but not for solifenacin (-0.01, 95%CI -0.03 to 0.00). In addition, in the subgroup analyses, a statistically significant association of delirium was found for oxybutynin but not for solifenacin in the non-dementia cohort (2.11,95% CI 1.08-4.13) and the dementia cohort (1.25, 95%CI 0.05-26.9)., Conclusion: The study found that oxybutynin but not solifenacin is associated with a risk of new-onset delirium in older adults. The higher blockade of M1 and M2 receptors by oxybutynin is likely to contribute to delirium than solifenacin, which is highly selective for the M3 receptor subtype. Therefore, the treatment choice with an M3 selective agent must be given due consideration, particularly in those with pre-existing cognitive impairment., (© 2022 The Authors.

Context: The choice of the most efficacious drug for patients with idiopathic overactive bladder (IOAB) remains challenging., Objective: The aim of this network meta-analysis was to determine the most efficacious oral antimuscarinic or β-adrenoceptor agonist accounting for adverse events for the management of IOAB., Evidence Acquisition: A comprehensive electronic search was done in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, and Ovid for studies in any language in February 2021 considering the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. We included all randomized controlled trials assessing oral antimuscarinics or β-adrenoceptor agonists for the treatment of IOAB. We determined the effect of specific bothersome symptoms separately., Evidence Synthesis: Fifty-four articles were included in our analysis. The most efficacious agents considering the evaluated outcomes were oxybutynin 15 mg/d in reducing incontinence episodes, imidafenacin 0.5 mg/d together with solifenacin 10 and 5 mg/d in reducing micturition episodes, fesoterodine 4 and 8 mg/d as well as solifenacin 10 mg/d in reducing urgency episodes, imidafenacin 0.5 mg/d and solifenacin 10 mg/d in reducing urgency urinary incontinence episodes, and solifenacin 10 mg/d, vibegron 50 mg/d, and fesoterodine 8 mg/d in improving the voided volume. Gastrointestinal problems, especially due to antimuscarinic agents, were the most prevalent adverse events., Conclusions: Taken together, there is only minimal difference between the efficacy of oral antimuscarinics and that of β-adrenoceptor agonists. Although finding the best medication for all is impossible, finding the best treatment for every individual patient can be done by considering the efficacy of a medicine for the most bothersome symptom(s) in balance with drug-specific adverse events., Patient Summary: This study aimed to find the most efficient oral medication to treat overactive bladder, taking into consideration the adverse events. Based on our study, there is a minimal difference in the efficacy between the two major drug classes used to treat overactive bladder. Gastrointestinal problems were the most common adverse events in medical treatment of overactive bladder. Selection of the best treatment is possible through shared decision-making between the doctor and the patient based on the patient's most bothersome symptom. We provide a framework for physicians to facilitate shared decision-making with each individual patient., (Copyright © 2021. Published by Elsevier B.V.)

Background/aim: In clinical practice, constipation is one of the most frequent adverse events caused by drugs for overactive bladder (OAB). The occurrence of constipation greatly deteriorates the patient's quality of life. The aim of the study was to evaluate and compare the effects of three commonly used β3 agonists and anticholinergic drugs on the defecation status in patients with OAB., Patients and Methods: We retrospectively reviewed the defecation status in patients who received mirabegron, solifenacin, or fesoterodine for OAB. We evaluated changes in the (a) urological parameters using the OAB symptom score (OABSS) and (b) defecation status using the Bristol Stool Form Scale (BSFS) and constipation scoring system (CSS) following 12 weeks of drug administration., Results: We analyzed data from 165 patients (mirabegron=56, fesoterodine=52, and solifenacin=57). The solifenacin group showed a significant decrease in BSFS (from 3.2±1.0 at baseline to 2.3±12 post-treatment) and an increase in hardened stools (p<0.001). Elimination worsened as assessed by almost all items, and the total modified CSS scores worsened significantly from 4.8±2.6 points at baseline to 8.O±4.8 points after 12 weeks of solifenacin treatment (p<0.001). The mirabegron group showed no changes in any of the CSS items. In the fesoterodine group, the CSS scores for "completeness" and "assistance" increased significantly after treatment (p<0.001 and p=0.013, respectively)., Conclusion: All three drugs were effective for OAB. Mirabegron had almost no effect on constipation; fesoterodine, an anticholinergic drug, also had hardly any effect on defecation., (Copyright © 2022, International Institute of Anticancer Research (Dr. George J.

Antimuscarinics are first-line medication for management of overactive bladder with solifenacin being commonly prescribed. Angioedema is the swelling of mucosa and submucosal tissue. There are no published case reports of drug-induced angioedema involving solifenacin. We report a case of a 41-year-old man with spinal cord injury who presented with oedema of face, lips, tongue and associated pruritic urticaria after taking 5 mg of solifenacin. All other possible causes including food allergy, insect bite, hereditary angioedema, use of NSAIDs, ACE inhibitors and antibiotics were ruled out. The temporal association between solifenacin and angioedema and complete resolution of symptoms after discontinuing the drug suggest that solifenacin was the most probable cause of angioedema in our patient., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Importance: Antimuscarinic medications are often discontinued, and there is a paucity of data regarding patient experience of medications within this class., Objective: The objective of this study is to qualitatively explore patient experience of antimuscarinic medications used for overactive bladder using reviews on Drugs.com., Study Design: We examined reviews prior to February 2, 2020 (available since 2008) for oral antimuscarinic medications. User content was reviewed qualitatively via inductive content analysis. Investigators coded third-party impressions, categorizing each review as positive, mostly positive, mostly negative, or negative. The prevalence of side effects, themes, and impressions are described, with comparisons by drug using χ2, Mann-Whitney U, and Kruskal-Wallis tests, as appropriate. Correlation between ordinal and categorical variables was performed using Tau and Spearman correlation coefficients, respectively., Results: We analyzed 469 user reviews. 68.2% reported symptom improvement. The most common side effects were dry mouth (29%) and fatigue (10.7%). Fewer neurologic side effects were reported in the solifenacin (13.9%) and trospium (none) groups (P = 0.009). Tolterodine and trospium immediate release had lower rates of ears, nose, and throat side effects (22.5% and 26.2%, respectively, P = 0.001.) Analysis of themes suggested 2 domains driving overall satisfaction: improvement and side effects. Improvement was associated with a positive satisfaction score (ρ = 0.64, P < 0.001) and gestalt impression (ρ = 0.74, P < 0.001). The factors that most negatively affected these measures were persistent symptoms followed by gastrointestinal side effects (P < 0.001)., Conclusions: Our data suggest important differences within this class of medication both in terms of side effects and patient satisfaction. Furthermore, symptom improvement is the leading factor for patient satisfaction, whereas gastrointestinal side effects are associated with dissatisfaction., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2022 American Urogynecologic Society.

The use of bladder antimuscarinics is very common in the elderly. However, recent population-based studies that assessed the use of anticholinergics or bladder antimuscarinics showed an increased risk of dementia when these drugs were used for a prolonged period. Several of these population-based studies included patients who used solifenacin, which is a bladder antimuscarinic released in 2005 with the prospect of being a more selective antimuscarinic for M3 receptors (M3R), which could make it a safer drug when trying to avoid unwanted effects of older bladder antimuscarinics such as oxybutynin, especially with regard to changes in cognition. Since the various bladder antimuscarinics have distinct pharmacological characteristics, such as in the ability to penetrate the blood-brain barrier, in selectivity for muscarinic receptors, and in brain efflux mechanisms, their effects on the central nervous system (CNS) may vary. Solifenacin was the drug selected in this review, which aims to describe the results of several articles published in recent years reporting the effects of solifenacin on cognition or the risk of dementia development. Although preclinical studies show that solifenacin can also act on brain M1 receptors (M1R), short-term clinical studies have shown it to be safe for cognition. However, there are no long-term randomized studies that prove the safety of this drug for the CNS. Thus, until the safety of solifenacin has been established by long-term studies, it seems advisable to avoid prolonged use of this drug in elderly patients.

Overactive bladder (OAB) is often treated with medications that block the cholinergic receptors in the bladder (known as anticholinergics). The effect of this medication class on cognition and risk of dementia has been increasingly studied over the past 40 years after initial studies suggested that the anticholinergic medication class could affect memory. Short-term randomized clinical trials demonstrated that the administration of the anticholinergic oxybutynin leads to impaired memory and attention, and large, population-based studies showed associations between several different anticholinergic medications and dementia. However, trials involving anticholinergics other than oxybutynin have not shown such substantial effects on short-term cognitive function. This discordance in results between short-term cognitive safety of OAB anticholinergics and the long-term increased dementia risk could be explained by the high proportion of patients using oxybutynin in the OAB subgroups of the dementia studies, or a study duration that was too short in the prospective clinical trials on cognition with other OAB anticholinergics. Notably, all studies must be interpreted in the context of potential confounding factors, such as when prodromal urinary symptoms associated with the early stages of dementia lead to an increase in OAB medication use, rather than the use of OAB medication causing dementia. In patients with potential risk factors for cognitive impairment, the cautious use of selected OAB anticholinergic agents with favourable physicochemical and pharmacokinetic properties and clinical trial evidence of cognitive safety might be appropriate., (© 2021.

Introduction and Hypothesis: The aim of this study is to report cognitive dysfunction with commonly used antimuscarinic overactive bladder medications in patients suffering from overactive bladder disorder with and without baseline neurologic conditions., Methods: We conducted an Ovid MEDLINE, Embase, and PsycINFO search from January 1998 to December 2018 using PRISMA guidelines. Eighteen studies met the inclusion criteria, including 5 randomized controlled trials and 13 observational studies., Results: Cognitive decline was reported with oxybutynin use (5 of 8 studies) and tolterodine use (4 of 7 studies) among patients with and without baseline cognitive impairment. Oxybutynin use was linked to functional, mental, and behavioral decline among patients with Alzheimer's disease (2 studies). No cognitive decline was detected among patients with and without baseline cognitive impairment taking trospium (6 studies), darifenacin (3 studies), imidafenacin (2 studies), and fesoterodine (1 study). Solifenacin was not associated with cognitive decline (2 studies) but was linked to an increased risk of dementia among patients with diabetes (1 study)., Conclusion: In this review, cognitive decline was reported with oxybutynin and tolterodine use and should be used with caution in adults over 65 years of age. Solifenacin, fesoterodine, and imidafenacin showed mixed results related to central nervous system effect. Trospium and darifenacin were not associated with cognitive decline among patients with and without baseline cognitive impairment., (© 2021. The International Urogynecological Association.)

Purpose: The purpose of this study is to investigate the efficacy and safety of mirabegron versus solifenacin in the treatment of newly diagnosed overactive bladder (OAB) in children., Methods: We conducted a prospective randomized controlled study on pediatric patients with newly diagnosed OAB. Patients were randomized into 3 groups: mirabegron (50 mg once daily) in group I, solifenacin (5 mg) in group II, and placebo in group III. Before starting our treatment and at the end of the 3 months course, we obtained a 3-day voiding diary. This diary included incontinence episode per day, mean voided volume per micturition, mean number of micturition per day, and post-void residual urine. Moreover, the parents/patients were asked to rate symptom relief, and the adverse events were recorded throughout the study period., Results: A total of 190 patients aged from 5 to 14 years completed this study. At the end of this trial, both groups I and II showed significant improvement versus placebo regarding our efficacy parameters with no significant difference between group I and II. The overall success rate based on assessment of symptom relief was significantly higher in the treated groups (87.5% in I and 90.2% in II) versus placebo (55.8%). Dry mouth was reported in 2.8, 10, and 0% and constipation in 2.8, 11.4, and 1.4% in group I, II, and III, respectively, without statistically significant difference between group I and placebo. However, there was a significant difference between group II and placebo regarding these side effects., Conclusion: Both mirabegron and solifenacin have comparable efficacy regarding the control of OAB symptoms in the newly diagnosed children, but mirabegrone seems to have less side effects., (© 2021 S.

Objective: To determine the patient-perceived effectiveness and tolerability of mirabegron compared to solifenacin in a multiple sclerosis (MS) population with overactive bladder (OAB) symptoms., Materials and Methods: MS patients with OAB symptoms who were not on medication for their urinary symptoms at enrollment were prospectively recruited. Patients enrolled in years 1-2 were prescribed mirabegron, whereas patients enrolled in years 3-4 were prescribed solifenacin. At enrollment and 6-week follow-up, patients completed several patient reported outcome measures. The primary outcome was change in OAB Questionnaire Short Form (OAB-q SF) symptom severity and minimal clinically important difference (MCID) achievement. The Patient Assessment of Constipation Symptoms (PAC-SYM) was used to assess bowel function over the treatment period., Results: Sixty-one patients were enrolled. The majority of the mirabegron (70%) and the solifenacin (69%) group achieved the OAB-q SF symptom severity MCID. The solifenacin group had a statistically significant greater decrease in its end of study OAB-q SF score (Δ = -37.87 vs -20.43, P = .02). Constipation improved in the mirabegron group and worsened in the solifenacin group (ΔPAC-SYM = -0.38 vs +0.22; P = .02), with 30% of patients prescribed solifenacin experiencing worsening above the MCID threshold., Conclusion: Among MS patients, we demonstrated similar response rates to mirabegron and solifenacin, with approximately 50%-70% achieving each patient reported outcome measure's MCID. Though this small study showed some short-term evidence that improvement in urinary symptom severity was greater with solifenacin, this potential benefit must be weighed against the observed risk of worsening constipation. Further studies are needed to confirm these findings., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Objective: To evaluate the effects of solifenacin, darifenacin, and propiverine on nasal-, subfoveal-, temporal choroidal thicknesses (NCT, SFCT, TCT), intraocular pressure (IOP) and pupil diameter (PD)., Materials and Methods: Patients with overactive bladder (OAB) diagnosed according to The International Continence Society were administered with solifenacin, darifenacin or propiverine on a daily basis between November 2017 and May 2018. NCT, SFCT, TCT, IOP, and PD of these patients were measured and compared as initial, fourth and twelfth weeks., Results: A total of 165 patients (330 eyes) with OAB were evaluated. Solifenacin (n=140) signifi cantly reduced IOP from 17.30±2.72 mmHg to 16.67±2.56 mmHg (p=0.006) and 16.57±2.41 mmHg (p=0.002), at the fourth and twelfth weeks, respectively. Darifenacin (n=110) signifi cantly reduced NCT from 258.70±23.96 μm to 257.51±22.66 μm (p=0.002) and 255.36±19.69 μm (p=0.038), at the fourth and twelfth weeks, respectively. Propiverine (n=80) signifi cantly increased PD from 4.04±0.48 mm to 4.08±0.44 mm (p=0.009) and 4.09±0.45 mm (p=0.001), at the fourth and twelfth weeks, respectively., Conclusion: These findings can help to decide appropriate anticholinergic drug choice in OAB patients. We finally suggest further well-designed randomized prospective studies with a larger population to evaluate the anticholinergic-related complications in eyes., Competing Interests: None declared., (Copyright® by the International Brazilian Journal of Urology.)

Objective: This analysis was conducted to investigate the cardiovascular (CV) safety outcomes from the MILAI II study. MILAI II was conducted to evaluate the long-term safety and efficacy of antimuscarinic add-on therapy to mirabegron over 52 weeks in patients with overactive bladder (OAB) symptoms., Methods: MILAI II consisted of a 2-week screening period (patients received mirabegron 50 mg once daily) plus a 52-week treatment period (patients were randomized to receive a combination of mirabegron 50 mg/d plus solifenacin 5 mg/d, propiverine 20 mg/d, imidafenacin 0.2 mg/d, or tolterodine 4 mg/d). CV safety was assessed using treatment-emergent adverse events (TEAEs), vital signs, and 12-lead electrocardiograms (ECGs). Vital signs and ECG data were evaluated for each patient using worst post-baseline values reported., Results: Of 647 patients, 570 (88.1%) were female with a mean age of 65 years. CV history at baseline and CV-related concomitant medication use throughout the study were balanced between groups. The incidences of overall and drug-related CV TEAEs were ≤8.1% and ≤6.2%, respectively, for all groups. The most common TEAEs were ECG T wave amplitude decreased, ECG QT prolonged, and ventricular extrasystoles. Overall, 36 TEAEs of interest related to the CV system that were possibly/probably related to treatment were reported with similar incidences for each group. For the worst post-baseline vital signs and ECGs, no relationships were noted in terms of either timing or treatment group., Conclusion: A favorable CV safety profile was observed following long-term combination treatment with mirabegron and an antimuscarinic in patients with OAB symptoms., (© 2019 The Authors.

Background: Mirabegron, a β3-adrenoreceptor agonist, is an alternative drug to antimuscarinics for overactive bladder (OAB) symptoms., Objective: To summarise safety and efficacy reporting of mirabegron treatment for OAB symptoms., Design, Setting, and Participants: Pooled data analysed from 10 phase 2-4, double-blind, 12-wk mirabegron monotherapy studies in adults with OAB who had received one or more doses of study drug., Intervention: Mirabegron: 25 and 50mg; antimuscarinics: solifenacin (2.5, 5, and 10mg) and tolterodine extended release (4mg)., Outcome Measurements and Statistical Analysis: Baseline OAB-related characteristics, intrinsic and extrinsic factors, and analyses by age (<65 vs ≥65yr and <75 vs ≥75yr) and sex were assessed. Solifenacin 2.5 and 10mg groups were not included in the efficacy analyses (small patient numbers). Safety was evaluated using the proportion of treatment-emergent adverse events. Efficacy variables were derived from bladder diaries (baseline and week 12)., Results and Limitations: Baseline hypertension and diabetes were more frequent across treatment groups in the older versus younger age groups and in men versus women. Within sexes, frequencies were similar between treatment groups. Some differences were observed in baseline characteristics, including type of incontinence and medical history between sexes. No previously unreported safety concerns were identified. Improvements in efficacy (mean number of incontinence episodes/24h, micturitions/24h, urgency episodes/24h, volume voided/micturition, and nocturia episodes) versus placebo were observed in all treatment groups. Significant treatment-by-subgroup interactions included change from baseline in the mean number of incontinence episodes/24h by age (<65 vs ≥65yr), nocturia by age (<65 vs ≥65yr and <75 vs ≥75yr), and urgency episodes by previous OAB medication., Conclusions: Data from this integrated database of 10 mirabegron studies reaffirm the safety and efficacy profiles of mirabegron, solifenacin, and tolterodine in adults of different age groups and sexes., Patient Summary: Overactive bladder is a complex of symptoms including a compelling desire to pass urine that leads to increased frequency, which may lead to a degree of incontinence if you do not reach the toilet in time and may wake you from sleep. We pooled data from 10 different studies of mirabegron in patients with overactive bladder symptoms, and looked at the effect in the total number of patients who received the treatment, as well as in different age groups and between men and women. No new safety concerns were identified, and mirabegron improved the symptoms of overactive bladder., (Copyright © 2019 The Author(s). Published by Elsevier B.V. All rights reserved.)

To assess the efficacy and safety of 2 drugs for overactive bladder (OAB), solifenacin and mirabegron. Fortyseven female OAB patients were randomized into 2 groups. Twenty-three patients were initially prescribed solifenacin for 4 weeks, followed by mirabegron for 4 weeks (group S). The other 24 patients were initially prescribed mirabegron for 4 weeks, followed by solifenacin for 4 weeks (group M). Evaluations included clinical determination of the OAB symptom score (OABSS), International Prostate Symptom Score (IPSS), and Visual Analog Scale. The IPSS significantly improved after the administration of solifenacin in both groups. The OABSS significantly improved in both groups after 4 weeks. In group M, the OABSS after eight weeks was significantly improved compared to that after 4 weeks. However, in group S, it was not significantly improved. Twelve patients experienced adverse events during the solifenacin treatment, while 2 patients experienced adverse events during the mirabegron treatment. Both solifenacin and mirabegron led to improved OAB symptoms. Switching from mirabegron to solifenacin significantly improved the OABSS. However, mirabegron led to fewer adverse events than solifenacin. We recommend that mirabegron be prescribed first for OAB patients. If patients are not satisfied with mirabegron, solifenacin should be used., Competing Interests: No potential conflict of interest relevant to this article was reported.

Objective: The aim of this study was to investigate the efficacy and safety of tadalafil add-on therapy with α 1 -adrenoceptor antagonists., Methods: Patients with persistent storage symptoms refractory to α 1 -adrenoceptor antagonists for benign prostatic hyperplasia were enrolled in the study. Patients were randomly assigned to either a 5 mg tadalafil or 5 mg solifenacin treatment group for 12 weeks. International Prostate Symptom Score, Overactive Bladder Symptom Score, urinary flow rates, residual urine volume, and blood pressure were measured prospectively before treatment and after 4 and 12 weeks of treatment. Changes from baseline were compared between groups. The rate of treatment discontinuation due to adverse effects was evaluated., Results: Of the 75 patients recruited to the study, 38 and 37 were assigned to the tadalafil and solifenacin groups, respectively. There were no significant difference in baseline characteristics between the two groups. The change in the amount of residual urine volume was significantly larger in the solifenacin- than tadalafil-treated group; other parameters, including lower urinary tract symptoms and uroflowmetry measures, did not differ significantly between the two groups. Seven (18%) and 12 (32%) patients in the tadalafil and solifenacin groups, respectively, discontinued treatment because of adverse events. The main reasons for discontinuation in the tadalafil group were stomach discomfort or nausea and dizziness or vertigo; voiding difficulty and constipation were the main reasons for discontinuation in the solifenacin group. There was no significant difference in blood pressure fluctuations from baseline between the two groups., Conclusions: Tadalafil add-on therapy was not inferior to solifenacin add-on therapy in terms of effect and safety. Therefore, tadalafil could be an alternative add-on drug for patients with persistent lower urinary tract symptoms refractory to α 1 -adrenoceptor antagonists., (© 2018 John Wiley & Sons Australia, Ltd.)

Objectives: To evaluate the long-term safety (primary objective) and efficacy (secondary objective) of antimuscarinic add-on therapy in patients receiving mirabegron., Methods: During a 2-week screening period, patients (aged ≥20 years, mirabegron treatment for ≥6 weeks, residual overactive bladder symptoms) received mirabegron 50 mg once daily. These patients were subsequently randomized to 52 weeks' treatment with mirabegron 50 mg/day plus an antimuscarinic (solifenacin 5 mg, propiverine 20 mg, imidafenacin 0.2 mg, or tolterodine 4 mg) with the potential to double the antimuscarinic dose (except for tolterodine) at week 8. Safety assessments included treatment-emergent adverse events, vital signs, 12-lead electrocardiograms, post-void residual volume, and laboratory evaluations. Efficacy was assessed using changes from baseline in overactive bladder symptom score total score; overactive bladder questionnaire short form score; micturitions, urgency episodes, urinary incontinence episodes, and urgency urinary incontinence episodes/24 h; mean volume voided per micturition; and number of night-time micturitions., Results: Overall, 80.2% of patients (88.1% women, mean age 65 years) experienced at least one treatment-emergent adverse event, with similar rates for all treatments. The adverse events most commonly reported were dry mouth, nasopharyngitis, and constipation. No marked change was observed in systolic or diastolic blood pressure for any treatment, although pulse rate increased slightly in the mirabegron and propiverine, and mirabegron and tolterodine groups. For all treatments, significant improvements were observed in all efficacy parameters, including overactive bladder symptom score total and questionnaire short form scores., Conclusions: Antimuscarinic add-on therapy is well tolerated and effective after initial treatment with mirabegron in patients with overactive bladder symptoms., (© 2018 The Authors.

Aim: We conducted a meta-analysis to evaluate the safety and efficacy of mirabegron (50 mg) and solifenacin (5 mg) monotherapy for overactive bladder (OAB) during a 12-week cycle., Methods: Randomized controlled trials (RCTs) of mirabegron and solifenacin for OAB were searched systematically by using MEDLINE, EMBASE, and the Cochrane Controlled Trials Register. The reference lists of retrieved studies were also perused., Results: Five RCTs which compared solifenacin with mirabegron were studied. Mirabegron achieved the same effect as solifenacin in treating OAB. The mean number of incontinence episodes per 24 h (P = 0.20), mean number of micturitions per 24 h (P = 0.11), mean number of urgency episodes per 24 h (P = 0.23), and mean volume voided per micturition (P = 0.05) suggested that mirabegron and solifenacin had no significant differences in terms of OAB treatment. With regard to drug-related treatment-emergent adverse events (DR-TEAEs) and dry mouth, mirabegron showed better tolerance than solifenacin. Post-voiding residual volume showed a distinct difference in the two groups. Hypertension and tachycardia did not show a significant difference between the two groups, but the pulse rate did., Conclusion: The therapeutic effect of mirabegron is similar to that of solifenacin, and mirabegron does not increase the risk of adverse events (AEs)., (© 2018 Wiley Periodicals, Inc.)

Objectives: This meta-analysis was to assess solifenacin and tolterodine in patients with overactive bladder., Methods: We searched PubMed, the Cochrane Library, EMBASE, CNKI, Wanfang, and ClinicalTrials.gov databases for randomized controlled trials (RCTs). The efficacy endpoint was daily micturition frequency, daily urgency episodes, daily incontinence episodes, and micturition volume per voiding. The safety endpoint was the incidence of the rate of major bleeding, intracranial bleeding, and gastrointestinal bleeding., Results: Seven RCTs met the inclusion criteria and 1,318 patients were included. The meta-analysis showed that, compared with tolterodine, solifenacin was associated with similar daily micturition frequency, daily urgency episodes, daily incontinence episode, and micturition volume per voiding at 8 and 12 weeks of follow-up. Moreover, no significant difference was obtained in the incidence of dry mouth between solifenacin and tolterodine at 8 and 12 weeks of follow-up. However, tolterodine decreased the constipation rate at 12 weeks compared with solifenacin., Conclusion: Solifenacin and tolterodine yielded similar results on daily micturition frequency, daily urgency episodes, daily incontinence episodes, micturition volume per voiding, and the incidence of dry mouth. However, tolterodine can decrease the constipation rate at 12 weeks compared with solifenacin., (© 2019 S. Karger AG, Basel.)

Objective: The aim of the present study was to prospectively evaluate the effect of aclatonium on dry mouth in patients with overactive bladder (OAB) after treatment with solifenacin., Methods: A multicenter randomized double-blind controlled trial was conducted. The study subjects were men and women who had been diagnosed with OAB for ≥3 months and presented with a total Overactive Bladder Symptom Score (OABSS) ≥3. Eligible subjects were randomized to receive 5 mg solifenacin with placebo or 5 mg solifenacin with 150 mg aclatonium once daily for 8 weeks. Subjects rated dry mouth using a visual analog scale (VAS) and completed the OAB-questionnaire (OAB-q) short form (SF) and OABSS questionnaires at baseline and after 8 weeks treatment. Dry mouth was defined as a VAS score >30 points (range 0-100)., Results: Overall, 92 patients (49 and 43 in the placebo and aclatonium groups, respectively) completed the 8-week treatment. In patients who had dry mouth at baseline, no differences were detected in changes in the dry mouth VAS, OABSS, or OAB-q SF scores between the 2 groups. However, in patients who had no dry mouth at baseline, the change in dry mouth VAS score was significantly lower in the aclatonium- than placebo-treated group: the VAS score increased 20 points in the placebo group compared with 9 points in the aclatonium group (P = .03). However, there were no significant differences in changes in the OABSS and OAB-q SF scores between the 2 groups., Conclusions: Aclatonium decreased dry mouth without disturbing treatment efficacy in patients who did not have dry mouth before treatment., (© 2017 John Wiley & Sons Australia, Ltd.)

Introduction: Correction of benign prostatic hyperplasia (BPH) with lower urinary tract (LUT) symptoms (LUTS) is treated with drugs of different pharmacological classes having side effects including suppression of sexual function., Aim: To assess the effect of simultaneous intake of dutasteride and solifenacin on the reversibility of severe LUTS and sexual function in men with BPH., Methods: Patients from group A took dutasteride 0.5 mg/d, those from group В took dutasteride 0.5 mg/d and solifenacin 10 mg/d, and those from group С took dutasteride 0.5 mg/d and solifenacin 20 mg/d. The duration of the observation was 6 months. The sexual function was rated with the International Index of Erectile Function questionnaire and Men's Sexual Health Questionnaire-ejaculatory dysfunction. The functional status of LUT was rated with International Prostate Symptom Score, overactive bladder questionnaire-awareness tool, diary voiding, and uroflowmetry., Main Outcome Measure: The state of sexual function and function of the LUT in men improved., Results: The erectile function in all men, having participated in the study, did not change [group A, 9.8 (1.6)/9.4 (3.8), P ≥ .05; group B, 10.1 (2.1)/10.5 (3.7), P ≥ .05; group C, 9.7 (1.5)/9.5 (2.6), P ≥ .05]. The ejaculator function significantly decreased in all groups. According to International Prostate Symptom Score, obstruction diminished in this group [incomplete emptying, 3.7 (0.7)/1.5 (0.3), P ≤ .05; intermittence, 3.5 (1.0)/3.5 (1.0), P ≤ .05; weak stream, 3.8 (0.6)/1.5 (0.4), P ≤ .05; straining, 3.4 (0.5)/0.7 (0.7), P ≤ .05] as did hyperactivity [urgency, 2.8 (0.7)/0.9 (0.7), P ≤ .05; nocturia, 2.8 (0.6)/1.2 (0.4), P ≤ .05]. All numbers in the manuscript are given in points unless otherwise stated. The values in parentheses are SD (unless otherwise specified)., Clinical Implications: The information that a high dose of solifenacin administered concomitantly with dutasteride may contribute to increase in sexual satisfaction and preservation of erectile function at the baseline level can be useful and used by sexologists, urologists, and family doctors., Strength & Limitations: The combination of dutasteride 0.5 mg/d and solifenacin 10 mg/d saves erectile function and improves sexual satisfaction. At the same time, the symptoms of obstruction and hyperactivity disappear or are reduced in most patients. Nevertheless, we did not study late results of the combined therapy., Conclusion: Suggested combination does not impact on erectile function but decreases ejaculator function; however, it does not affect a general high rating of sexual function by patients. Thus, overall sexual function in men with BPH and severe LUTS is not impaired by prolonged intake of double dosage of solifenacin combined with dutasteride. The combination of dutasteride and solifenacin is effective and safe to treat BPH and severe LUTS. Kosilov K, Kuzina I, Kuznetsov V, et al.

Background: The long-term potential of solifenacin and mirabegron combination treatment for patients with overactive bladder (OAB) has not been previously assessed., Objectives: To evaluate the safety and efficacy of solifenacin succinate 5mg plus mirabegron 50mg tablets (combination treatment) versus solifenacin or mirabegron monotherapy in patients with OAB over 12 mo., Design, Setting, and Participants: Randomised, double-blind, multicentre, phase 3 trial (SYNERGY II) of patients with "wet" OAB symptoms (urinary frequency and urgency with incontinence) for ≥3 mo. The study was conducted from March 2014 to September 2016; with 1829 patients randomised. The full analysis set was comprised of 1794 patients., Outcome Measurements and Statistical Analysis: The primary objective was safety, measured as treatment-emergent adverse events (TEAEs). Efficacy was measured as the change from baseline to the end of treatment in the mean number of incontinence episodes/24h and micturitions/24h., Results and Limitations: The median age was 60 yr (range 19-86 yr) and 1434 patients (80%) were female. Overall, 856 patients (47%) experienced ≥1 TEAE. TEAE frequency was slightly higher in the combination group (596 patients, 49%; mirabegron 126 patients, 41%; solifenacin 134 patients, 44%). Serious TEAEs were reported by 67 patients (3.7%); one was considered possibly treatment-related (mirabegron group, atrial fibrillation). Dry mouth was the most common TEAE (combination 74 patients, 6.1%; solifenacin 18 patients, 5.9%; mirabegron 12 patients, 3.9%). Combination therapy was statistically superior to mirabegron and solifenacin for the number of incontinence episodes (vs mirabegron: adjusted mean difference [AMD] -0.5, 95% confidence interval [CI] -0.7 to -0.2, p<0.001; vs solifenacin: AMD -0.1, 95% CI -0.4 to 0.1, p=0.002) and micturitions (vs mirabegron: AMD -0.5, 95% CI -0.8 to -0.2, p<0.001; vs solifenacin: AMD -0.4, 95% CI -0.7 to -0.1, p=0.004)., Conclusions: Mirabegron and solifenacin combination treatment for OAB symptoms was well tolerated over 12 mo and led to efficacy improvements over each monotherapy. This innovative combination is a treatment option that could become widely used in the clinic., Patient Summary: This study looked at the safety and efficacy of a combination of solifenacin succinate 5mg plus mirabegron 50mg tablets over 12 mo in patients with the overactive bladder (OAB) symptoms of increased urination frequency, heightened urgency to urinate, and unintentional passing of urine. We compared this treatment with solifenacin succinate 5mg or mirabegron 50mg alone, and found that the combination treatment was well tolerated by patients and led to greater improvements in symptoms. This novel combination could be an improved treatment option in the clinical setting for patients with OAB. This study is registered at ClinicalTrials.gov as NCT02045862., (Copyright © 2018 The Authors. Published by Elsevier B.V. All rights reserved.)

Objectives: To compare persistence with medication and the reasons for discontinuation of mirabegron or solifenacin therapy up to12 months in women with overactive bladder (OAB)., Methods: Female OAB patients who presented to women's urology clinics were enrolled in a prospective, randomized, two-arm study. Patients were randomized to receive mirabegron at 25-50 mg (n = 76) or solifenacin at 2.5-5 mg (n = 72). The persistence rate and the reasons for discontinuation were investigated up to 12 months., Results: The 12-month persistence rate was 12.2% in the mirabegron group versus 20.1% in the solifenacin group and there were no significant differences of the persistence rates during the study (n.s). Patients discontinued treatment because of lack of efficacy (21.6%), spontaneous improvement (18.2%), and side-effects (17.6%), while 19.6% were lost to follow up. Discontinuation due to side-effects was significantly more frequent in the solifenacin group than the mirabegron group (27.3 vs. 7.9%, P < 0.05). In contrast, discontinuation due to lack of efficacy was significantly more frequent in the mirabegron group than the solifenacin group (36.8 vs. 5.6%, P < 0.05)., Conclusions: This study demonstrated low persistence rates over 12 months for both mirabegron and solifenacin, although the reasons for discontinuation were somewhat different., (© 2016 John Wiley & Sons Australia, Ltd.)

Objective: To evaluate the efficacy and safety of gabapentin in comparison to solifenacin succinate and placebo for the treatment of adult patients with overactive bladder (OAB)., Method: A 12-week, randomized, double-blind, double dummy placebo-controlled, clinical trial was conducted between October 2010 and August 2014 at a tertiary medical center. Eligible and consenting patients included were randomized into three treatment groups (placebo, gabapentin and solifenacin). After a 12-week treatment period, an intention to treat analysis was applied to assess between group differences on the micturitions and urgency episodes per 24 h; which were evaluated by 3-day micturition diary mean change from baseline to post treatment. Health related quality of life (HRQOL) domains were likewise assessed by OAB questionnaire (OAB-q). Adverse event were monitored and summarized. Study results were analyzed at statistical significance of 0.05. (ClinicalTrials.gov ID NCT01486706) RESULT: A total of 94 participants were included for end-study efficacy and safety analysis. Compared to placebo, gabapentin and solifenacin have statistically significant improvement in mean number of micturitions per 24 h (adjusted mean difference [AMD] -1.179, 95%CI -1.98, -0.38; P < 0.001; -1.706, 95%CI -2.52, -0.09; P < 0.001; respectively), and in mean number of urgency episodes per 24 h (AMD -0.903, 95%CI -1.44, -0.37; P < 0.001; -0.896, 95%CI -1.44, -0.35; P < 0.001). Gabapentin also demonstrated significant improvement over the solifenacin in the mean number of nocturia episodes/24 h (AMD -0.607, 95%CI -1.04, -0.18; P < 0.001). Adverse event related to gabapentin treatment was lesser than solifenacin, and comparable to placebo., Conclusion: Gabapentin treatment with acceptable safety profile, improves OAB symptoms and HRQOL domains., (© 2017 John Wiley & Sons Australia, Ltd.)

Aim: The aim of this study was to compare the efficacy and tolerability of solifenacin and mirabegron in patients with overactive bladder (OAB) syndrome., Methods: We carried out a retrospective analysis in 342 women affected by OAB syndrome; 168 were treated with solifenacin 5 mg/daily and 174 with mirabegron 50 mg/daily. A clinical evaluation, 3-day voiding diary, and urodynamic testing was performed. Patients completed the Overactive Bladder Questionnaire - Short Form, the King's Health Questionnaire, and the Patient Global Impression of Improvement questionnaire. The adverse effects were evaluated. The two groups were compared at baseline and at 12 weeks., Results: After 12 weeks, a significant reduction in the mean number/24 h of voids and urgent micturition episodes/24 h was observed in both groups. Detrusor overactivity decreased from 58.3% to 13.1% in the solifenacin group and from 58% to 11% in the mirabegron group. Twenty (12%) and 18 (10.7%) patients taking solifenacin reported constipation and dry mouth, respectively, versus four (2.3%) and five (2.9%) patients taking mirabegron, respectively, but there was no difference between the groups in the change in vital signs. The Overactive Bladder Questionnaire - Short Form and King's Health Questionnaire scores did not demonstrate significant differences and the abandonment rates in the solifenacin and mirabegron groups were 25.5% and 20%, respectively., Conclusion: Solifenacin and mirabegron showed the same efficacy in the treatment of OAB but solifenacin had more adverse effects., (© 2017 Japan Society of Obstetrics and Gynecology.)

Aims: To compare efficacy and tolerability of solifenacin 5 mg/day versus other oral antimuscarinic agents for the treatment of overactive bladder (OAB)., Methods: Literature searches of MEDLINE, Embase, and the Cochrane Library were undertaken to identify randomized controlled trials in OAB (2000-2015) for antimuscarinic agents. A network meta-analysis (NMA) was performed to estimate efficacy and tolerability outcomes for solifenacin 5 mg/day relative to other antimuscarinics., Results: The NMA included 53 eligible trials (published, n = 48; unpublished on search date, n = 5). Solifenacin 5 mg/day was significantly more effective than tolterodine 4 mg/day for reducing incontinence and urgency urinary incontinence (UUI) episodes, but significantly less effective than solifenacin 10 mg/day for micturition; no other statistically significant differences were noted for efficacy. Solifenacin 5 mg/day had a statistically significant lower risk of dry mouth compared with darifenacin 15 mg/day, fesoterodine 8 mg/day, oxybutynin extended-release 10 mg/day, oxybutynin immediate-release (IR) 9-15 mg/day, tolterodine IR 4 mg/day, propiverine 20 mg/day, and solifenacin 10 mg/day. There were no significant differences between solifenacin 5 mg/day and other antimuscarinics for risk of blurred vision, or for 11 of 17 active comparators for risk of constipation., Conclusions: This NMA suggests that the efficacy of solifenacin 5 mg/day is at least similar to other common antimuscarinics across the spectrum of OAB symptoms analyzed, and is more effective than tolterodine 4 mg/day in reducing incontinence and UUI episodes. Solifenacin 5 mg/day has a lower risk of dry mouth compared with several agents., (© 2017 The Authors. Neurourology and Urodynamics Published by Wiley Periodicals, Inc.)

Objectives: Details on the therapeutic effects of long-term antimuscarinic therapy have not been reported. Thus, the aim of this study is to evaluate the detailed long-term therapeutic effect of antimuscarinic therapy., Methods: All consecutive patients who visited the urologic outpatient clinics of a medical center for treatment of overactive bladder syndrome and received antimuscarinic therapy of 12 months or more were retrospectively reviewed. All medical records, including the Overactive Bladder Symptom score (OABSS), the modified Indevus Urgency Severity Scale and the International Prostate Symptoms score (IPSS) questionnaires, and uroflowmetry parameters were reviewed at each visit., Results: A total of 140 patients had received 12 months or more of antimuscarinic therapy. Sustained therapeutic effects were observed by persistent decreases of IPSS-storage score, IPSS-total score and OABSS score. Moreover, the maximum flow rate did not change over time. A temporary increase in postvoid residual volume and decrease in voiding efficiency were found, but these parameters improved over long-term visits. Side-effects were observed in 81 patients (57.9%) and included dry mouth (n = 58, 41.4%), constipation (n = 48, 34.3%) and blurred vision (n = 4, 2.9%); all side-effects were tolerable. Patients aged 75 years or more (n = 94) had a higher comorbidity rate (n = 46, 48.9%) before treatment but generally exhibited similar therapeutic effects as overall patients; elderly patients could also tolerate side-effects., Conclusion: Sustained therapeutic effects were observed in patients who received 12 months or more of antimuscarinic therapy, even in elderly patients. In addition, side-effects in patients receiving long-term therapy were also common but tolerable., (© 2016 John Wiley & Sons Australia, Ltd.)

Introduction: To assess efficacy and tolerability of a new complementary and alternative medicine (CAM) consisting of vitamins (C and D), herbal products (cucurbita maxima, capsicum annum, polygonum capsicatum) and amino acid L-Glutammina, in the treatment of female Overactive Bladder syndrome (OAB)., Materials and Methods: 90 consecutive women with OAB symptoms were enrolled in this prospective, randomized, controlled study. Women were divided randomly into two groups of 45 patients each. In group A, women received Solifenacin Succinate (SS), 5 mg. once a day for 12 weeks. In group B, women received CAM, 930 mg, twice daily for 12 weeks. Women were assessed with 3-day micturition diary, Patient Perception of Intensity of Urgency Scale (PPIUS), Overactive Bladder questionnaire Short Form (OAB-q SF) and Patient Global Impression of Improvement questionnaire (PGI-I)., Results: 8 patients in group A and 1 patient in group B dropped out from therapy because of side effects. A reduction in the number of daily micturitions, nocturia and episodes of urge incontinence was present with both SS and CAM with statistically highly significant differences, but CAM was significantly more effective than SS. PPIUS and OAB-q SF showed improvements with both SS and CAM with a more significant efficacy of CAM. PGI-I, demonstrated improvements in the two groups of patients with a greater satisfaction expressed by patients treated with CAM., Conclusions: the small number of patients does not permit definitive conclusions; however, the results of the research showed the greater effectiveness and tolerability of CAM.

Background: The BESIDE study demonstrated that combination therapy (mirabegron and solifenacin 5mg) improved overactive bladder symptoms versus solifenacin 5mg or 10mg, and was well tolerated., Objective: To ensure efficacy and safety is maintained in older patients (>65 yr), who usually experience greater symptom severity and comorbidities, a prespecified subanalysis stratified by age group was conducted., Design, Setting, and Participants: Patients remaining incontinent (≥1 episode during 3-d diary) following 4-wk single-blind daily solifenacin 5mg were randomized 1:1:1 to a daily double-blind combination (solifenacin 5mg and mirabegron 25mg, increased to 50mg at wk 4), solifenacin 5mg or 10mg for 12 wk. Four cohorts stratified by age (<65 yr, ≥65 yr and < 75 yr, ≥75 yr) were investigated., Outcome Measurements and Statistical Analysis: Efficacy assessments: change from baseline to end of treatment in average daily incontinence (primary) and micturition frequency (key secondary), number of incontinence episodes during the 3-d diary (key secondary), and change from baseline in average daily urgency and urgency incontinence episodes. Safety included treatment-emergent adverse events and vital signs., Results and Limitations: Full analysis set included 2110 patients: 30.9% aged ≥65 yr and 8.9% aged ≥75 yr. At the end of treatment, daily, and 3-d incontinence daily micturitions, urgency, and urgency incontinence, were improved in each treatment group and age group; the largest reductions were observed with combination in each age cohort. There were no notable differences in vital signs or the incidence of treatment-emergent adverse events between treatment and age groups, with the exception of dry mouth, which was highest with solifenacin 10mg., Conclusions: Efficacy and safety in the overall population is maintained in older (≥65 yr) and elderly (≥75 yr) patients treated with a combination of solifenacin and mirabegron, or solifenacin monotherapy; irrespective of age, combination was associated with the greatest improvement in overactive bladder symptoms., Patient Summary: This study investigated the effectiveness and safety of a combination of two different treatments (mirabegron 50mg and solifenacin 5mg) or solifenacin (5mg or 10mg) alone in patients aged <65 yr or ≥65 yr, and <75 yr or ≥75 yr with overactive bladder. Symptoms of overactive bladder, such as the urgent need to visit the toilet, incontinence, and frequent urination, were improved with all treatments regardless of the patient's age, but combination treatment demonstrated the greatest benefit, and was well tolerated., (Copyright © 2017 European Association of Urology.

Objective: To evaluate the potential of solifenacin 5 mg combined with mirabegron 25 or 50 mg to deliver superior efficacy compared with monotherapy, with acceptable tolerability, in the general overactive bladder (OAB) population with urinary incontinence (UI)., Patients and Methods: After a 4-week placebo run-in, patients aged ≥18 years with wet OAB (urgency, urinary frequency and UI) for ≥3 months who recorded on average ≥8 micturitions/24 h, ≥1 urgency episode/24 h, and ≥3 UI episodes over the 7-day micturition diary, were eligible for randomisation to double-blind treatment [2:2:1:1:1:1 ratio, solifenacin 5 mg + mirabegron 25 mg (combined S5 + M25 group); solifenacin 5 mg + mirabegron 50 mg (combined S5 + M50 group); solifenacin 5 mg; mirabegron 25 mg; mirabegron 50 mg; or placebo for 12 weeks], and 2-weeks' single-blind, placebo run-out. Co-primary efficacy variables were change from baseline to end of treatment (EoT) in the mean number of UI episodes/24 h and micturitions/24 h, assessed using a 7-day electronic micturition diary. Secondary efficacy variables included change from baseline to EoT in the mean volume voided/micturition, change from baseline at weeks 4, 8, 12 and EoT in mean number of UI episodes/24 h, micturitions/24 h, urgency episodes/24 h, urgency UI (UUI) episodes/24 h and nocturia episodes/24 h; the percentage of patients (responders) achieving zero UI episodes/24 h at EoT in the last 7 days prior to each visit, micturition frequency normalisation (<8 episodes/24 h) at weeks 4, 8, 12 and EoT; and the number of UUI episodes and nocturia episodes in the 7-day diary. Safety assessments included incidence and frequency of treatment-emergent adverse events (TEAEs), post-void residual (PVR) urine volume, and changes from baseline in laboratory parameters., Results: Whilst the combined S5 + M50 group was superior to solifenacin 5 mg for UI, with a mean (standard error) adjusted difference of -0.20 (0.12) UI episodes/24 h (95% confidence interval -0.44, 0.04, P = 0.033), there was no statistical superiority vs mirabegron 50 mg [-0.23 (0.12) UI episodes/24 h; P = 0.052]. In secondary analyses, all active treatment groups had greater improvements in UI episodes/24 h vs placebo, with effect sizes for the combined therapy groups (combined S5 + M25 group: -0.70 episodes/24 h; combined S5 + M50 group: -0.65 episodes/24 h) that were substantially higher than those obtained with monotherapy (range -0.37 episodes/24 h for mirabegron 25 mg to -0.45 episodes/24 h for solifenacin 5 mg). For micturitions/24 h, adjusted change from baseline to EoT was greater in the combined therapy groups vs monotherapies (combined S5 + M50 group, nominal P values 0.006 and <0.001 vs solifenacin 5 mg and mirabegron 50 mg, respectively; combined S5 + M25 group, nominal P values 0.040 and 0.001 vs solifenacin 5 mg and mirabegron 25 mg, respectively). All active treatment groups had greater improvements in the mean numbers of micturitions/24 h vs placebo, with effect sizes for the combined therapy groups (combined S5 + M25 group: -0.85 micturitions/24 h; combined S5 + M50 group: -0.95 micturitions/24 h) higher than with mirabegron monotherapy (25 mg: -0.36; 50 mg: -0.39 micturitions/24 h) and solifenacin 5 mg (-0.56 micturitions/24 h). The combined S5 + M50 group was statistically significantly superior to both monotherapies at EoT for UUI episodes, urgency episodes and nocturia, with effect sizes that appeared to be additive. The combined S5 + M25 group was statistically significantly superior to mirabegron 25 mg for the same variables, except for nocturia. In responder analyses at the EoT, odds ratios in favour of both combined therapies vs monotherapies were shown for the proportion of patients with zero UI episodes and those achieving micturition frequency normalisation. There was a slightly increased frequency of TEAEs in the combined therapy groups vs monotherapies and placebo. Most of the TEAEs were mild or moderate in severity. Events indicative of urinary retention were reported slightly more frequently in the combined therapy groups vs monotherapy and placebo. PVR volume was slightly increased in the combined therapy groups vs solifenacin 5 mg, mirabegron monotherapy, and placebo groups. There were slightly higher frequencies of dry mouth, constipation, and dyspepsia in the combined therapy groups vs monotherapies. There were no concerns regarding electrocardiograms and laboratory data., Conclusion: In the largest OAB study to date, combined therapy with solifenacin 5 mg + mirabegron 25 mg and solifenacin 5 mg + mirabegron 50 mg provided consistent improvements in efficacy compared with the respective monotherapies across most of the outcome parameters, with effect sizes generally consistent with an additive effect. Although the combined S5 + M50 group did not achieve a statistically significant effect vs mirabegron 50 mg in the primary analysis of one of the co-primary endpoints (change from baseline in mean number of UI episodes/24 h), it approached statistical significance (P = 0.052), and the nominal P values for the other co-primary endpoint (micturitions/24 h) were <0.05. Most effects of combined therapy vs monotherapy were observable by week 4. The clinical relevance of the improvements seen with combined therapy for several objective OAB outcome measures was also supported by the improvements of combined therapy vs monotherapy in the responder analyses., (© 2017 The Authors.

Aims/objectives: In the BESIDE study, combination therapy (antimuscarinic [solifenacin] and β 3 -adrenoceptor agonist [mirabegron]) improved efficacy over solifenacin monotherapy without exacerbating anticholinergic side effects in overactive bladder (OAB) patients; however, a potential synergistic effect on the cardiovascular (CV) system requires investigation., Methods: OAB patients remaining incontinent despite daily solifenacin 5 mg during 4-week single-blind run-in, were randomised 1:1:1 to double-blind daily combination (solifenacin 5 mg/mirabegron 25 mg, increasing to 50 mg after week 4), solifenacin 5 or 10 mg for 12 weeks. CV safety assessments included frequency of CV-related treatment-emergent adverse events (TEAEs), change from baseline in vital signs (systolic blood pressure [SBP], diastolic blood pressure [DBP], pulse rate) and electrocardiogram (ECG) parameters., Results: The frequency of hypertension, tachycardia and ECG QT prolongation, respectively, was low and comparable across combination (1.1%, 0.3%, 0.1%), solifenacin 5 mg (0.7%, 0.1%, 0.1%), and solifenacin 10 mg groups (0.8%, 0%, 0.1%). Adjusted mean (SE) change from baseline to end of treatment (EoT) in SBP, DBP, and pulse rate with combination (0.07 mm Hg [0.38], -0.35 mm Hg [0.26], 0.47 bpm [0.28]), solifenacin 5 mg (-0.93 mm Hg [0.38], -0.45 mm Hg [0.26], 0.43 bpm [0.28]) and solifenacin 10 mg (-1.28 mm Hg [0.38], -0.48 mm Hg [0.26], 0.27 bpm [0.28]) was generally comparable, with the exception of a mean treatment difference of ~1 mm Hg in SBP between combination and solifenacin monotherapy; SBP was unchanged with combination and decreased with solifenacin monotherapy. Mean changes from baseline to EoT in ECG parameters were generally similar across treatment groups, except for QT interval corrected using Fridericia's formula, which was higher with solifenacin 10 mg (3.30 mseconds) vs. combination (0.49 mseconds) and solifenacin 5 mg (0.77 mseconds)., Conclusion: The comparable frequency of CV-related TEAEs, changes in vital signs and ECG parameters indicates no synergistic effect on CV safety outcomes when mirabegron and solifenacin are combined., (© 2017 The Authors International Journal of Clinical Practice Published by John Wiley & Sons Ltd.)

Introduction and Hypothesis: To investigate the effect of solifenacin succinate on intraocular pressure (IOP) and dry eye in patients with overactive bladder (OAB)., Methods: The study was conducted prospectively between October 2014 and November 2015. A total of 93 female OAB patients with a mean age of 48.59 ± 11.28 years (range 19-75 years) were evaluated. A full ophthalmic examination, including the Schirmer I test and IOP measurements, was conducted. Solifenacin succinate (5 mg/day) was started orally. All procedures were repeated at the 4- and 12-week follow-up, and the effects and side effects were documented., Results: No statistically significant difference was observed in IOP (p = 0.282, p = 0.189) and tear secretion (p = 0.122, p = 0.071) values from the baseline (day 0) to the 12th week in OAB patients using solifenacin succinate. Solifenacin succinate treatment was terminated in 3 patients owing to dry eye in 1 patient, increased IOP in 1 patient, and systemic side effects in 1 patient. Constipation and dry mouth at various rates were the most common systemic side effects observed., Conclusions: Solifenacin succinate is useful in eliminating OAB symptoms in female patients, but can cause systemic side effects. It had no significant side effects on tear secretion (Schirmer I) and IOP. We concluded that solifenacin succinate could be reliably used in pure OAB patients without comorbidity in terms of dry eye and IOP. We believe that prospective studies with larger series are still needed to reach a definite conclusion.

Background: Overactive bladder syndrome (OAB) is a common medical condition that causes significant distress and impact on the quality of life in women. Muscarinic receptor antagonists remain the mainstay of therapy, but they are limited by their efficacy and adverse effects. The objective of the article was to compare the clinical efficacy and tolerability of medications used to treat OAB in women through network meta-analysis., Methods: Data from eligible studies of commonly prescribed pharmacological agents in the treatment of OAB in women were entered into Net-MetaXL after a literature search using two online databases (PubMed and Cochrane). Studies between 31 July 2000 and 31 July 2015 were included in this study., Results: Five quantitative studies were eligible for analysis. The most efficacious drug to treat OAB in women appears to be solifenacin 10 mg once daily (OD), followed by oxybutynin 3 mg three times a day. However, solifenacin 10 mg OD caused more adverse effects that the other treatments., Discussion: Our results are similar to those of another systematic review. When considering efficacy, tolerability and cost, solifenacin 5 mg once daily is the drug of choice as it is more efficacious, albeit with more adverse effects, than other treatments. If solifenacin is unsuitable, oxybutynin 3 mg TDS is recommended.

Introduction: The emergence of urinary retention (UR), specifically acute urinary retention (AUR), has been a concern when treating men with lower urinary tract symptoms (LUTS) with antimuscarinic drugs., Materials and Methods: In NEPTUNE (12-week, double-blind), men (≥45 years) with LUTS were randomized to receive tamsulosin oral-controlled absorption system (TOCAS) 0.4 mg, fixed-dose combination (FDC) of solifenacin (Soli) 6 mg + TOCAS 0.4 mg, FDC Soli 9 mg + TOCAS 0.4 mg, or placebo. In NEPTUNE II (40-week, open-label extension of NEPTUNE), continuing patients received 4-week FDC Soli 6 mg + TOCAS, then FDC Soli 6 mg or 9 mg + TOCAS for the remainder of the study, switchable every 3 months., Results: Across both studies, 1208 men received ≥1 dose of FDC Soli 6 mg or 9 mg + TOCAS for up to 52 weeks; 1199 men completed NEPTUNE and 1066 received ≥1 dose in NEPTUNE II. In total, 13 men (1.1%; 95% CI, 0.6%-1.8%) reported a UR event while receiving FDC, eight of which were AUR (0.7%; 95% CI, 0.3%-1.3%, incidence 7/1000 man-years). Six men reported UR events while taking Soli 6 mg + TOCAS (three AUR), and seven men reported a UR event while taking Soli 9 mg + TOCAS (five AUR). One man developed AUR while taking TOCAS alone and four reported UR (three AUR) during placebo run-in. Most AUR/UR events occurred within 4 months of treatment initiation., Conclusions: FDC Soli and TOCAS was associated with a low rate of UR and AUR in men with LUTS., Competing Interests: This study was supported by Astellas Pharma Europe.

We investigated the efficacy and tolerability of solifenacin 5 mg fixed dose in children with newly diagnosed idiopathic overactive bladder (OAB). A total of 34 children (male/female patients = 16/18) aged under 13 years (mean age: 7.2 ± 2.3; range: 5-12) who were newly diagnosed with OAB from January 2012 to September 2014 were prospectively evaluated with open-label protocol. All patients were treated with solifenacin 5 mg fixed dose once daily for at least 4 weeks. The efficacy and tolerability of solifenacin were evaluated 4, 8, and 12 weeks after the initiation of treatment. The mean voiding frequency during daytime was decreased from 9.4 ± 3.0 to 6.5 ± 2.3 times after the 12-week treatment (P < 0.001). The mean total OAB symptom score (OABSS) decreased from 7.7 ± 4.2 to 3.1 ± 3.1 after the 12-week treatment (P < 0.001). The urgency and urgency urinary incontinence (UUI) domains significantly improved from the 12-week treatment, and complete resolution of urgency occurred in 38.9% of patients and the percentage of children with UUI among urgent patients decreased from 79.4% to 57.1%. According to 3-day voiding diaries, the average bladder capacity increased from 90.4 ± 44.4 to 156.2 ± 67.3 mL (P < 0.001). Drug-induced adverse effects (AEs) were reported in 7 patients (20.6%). Our results indicate that solifenacin 5 mg fixed dose is effective against OAB symptoms, and its tolerability is acceptable without significant AEs in children with OAB., Competing Interests: The authors have no potential conflicts of interest to disclose.

Aims: To investigate the effect on urodynamics of 4 weeks treatment with solifenacin succinate in patients with neurogenic detrusor overactivity (NDO) due to multiple sclerosis (MS) or spinal cord injury (SCI)., Methods: SONIC was a prospective, multicenter, double-blind, phase 3b/4 study investigating the efficacy and safety of solifenacin 10 mg in patients with NDO due to MS or SCI. Patients (n = 189) were randomized to placebo or active treatment (solifenacin 5 mg, 10 mg or oxybutynin hydrochloride 15 mg) for 4 weeks, after a 2-week, single-blind, placebo run-in period. The primary endpoint was change in maximum cystometric capacity (MCC) from baseline to end of treatment. The primary analysis compared solifenacin 10 mg versus placebo; all other comparisons were considered secondary. Secondary endpoints included changes in urodynamic parameters, patient-reported outcomes, and safety assessments., Results: In the primary analysis, solifenacin 10 mg significantly improved mean change from baseline MCC versus placebo (P < 0.001) and was associated with improvements in bladder volume at first contraction and at first leak as well as detrusor pressure at first leak. Similar results were obtained for oxybutynin versus placebo. Patient perception of bladder condition significantly improved with solifenacin 10 mg versus placebo (P = 0.041). There was a clear improvement in quality of life (QoL) in the solifenacin arms versus placebo. The overall incidence of adverse events was low., Conclusions: In patients with NDO due to MS and SCI, 4 weeks of treatment with solifenacin 10 mg improved urodynamic variables and QoL versus placebo and was well tolerated.

Introduction: The study aimed to evaluate the efficacy and safety of solifenacin in older patients with overactive bladder (OAB)., Materials and Methods: Observational data on patients aged ≥70 years and the prescribed flexible dose of solifenacin for OAB were collected at 294 offices of German general practitioners. Baseline and week 12 data included type and severity of OAB symptoms, adverse events, quality of life, and change in cognitive function per Mini Mental State Examination (MMSE)., Results: Mean age of 774 patients was 78 ± 6 years. A decrease was observed in all OAB symptoms including a reduction of urinary urgency and micturition, each by 4 episodes per 24 h. No change in mean MMSE scores was apparent at week 12. Adverse events and treatment discontinuations were low at 5.8 and 0.5%, respectively., Conclusion: Solifenacin was well-tolerated while OAB symptoms declined at week 12. No relevant effect of solifenacin on cognitive function was observed in this elderly population., (© 2017 S. Karger AG, Basel.)

Objective: The objective of this study was to evaluate the safety and efficacy of tamsulosin hydrochloride 0.2 mg (TAM) and its combination with solifenacin succinate 5 mg (SOL) after transurethral resection of the prostate (TURP)., Patients and Methods: The patients were randomized into three groups: TURP (group 1), TURP plus TAM (group 2), and TURP plus TAM + SOL (group 3). Patients in group 2 and group 3 received medication for 4 weeks. The primary efficacy end points were the mean change in total International Prostate Symptom Score (IPSS) and IPSS subscores. The secondary end points included quality-of-life score, Overactive Bladder Symptom Score, and short-form voiding and storage score of International Continence Society., Results: In total, 37 men (31.8%) in group 1, 37 men (31.8%) in group 2, and 42 men (36.2%) in group 3 completed the study. In total IPSS, no significant improvement was seen from baseline to the end of treatment in groups 2 and 3 compared with group 1. However, in group 2, the decrement in the IPSS storage score was smaller than group 1 ( P =0.02), and in group 3, the decrement in the IPSS voiding score was smaller than group 1 ( P =0.05). In groups 2 and 3 compared with group 1, improvements in the quality of life score, total score of Overactive Bladder Symptom Score, and short-form voiding score and storage score of International Continence Society were not statistically significant., Conclusion: Treatment with TAM and combination of TAM and SOL did not have significant additional benefits for lower urinary tract symptoms during the early recovery period after TURP.

Objective: To investigate the effect of oral solifenacin succinate on Schirmer I test results, tear break-up time (TBUT) and Ocular Surface Disease Index (OSDI) scores in overactive bladder (OAB) patients and to compare these results with those of healthy control subjects., Materials and Methods: The female OAB patients who were prescribed oral solifenacin succinate 5 mg/day (Group I, N = 80) and age-matched healthy female subjects (Group II, N = 40) were recruited for the study and underwent ophthalmological examination prior to oral treatment and after 4 weeks. They completed the OSDI questionnaire and underwent ocular surface tests including Schirmer I test and TBUT., Results: The statistical analysis of the Schirmer I test and TBUT revealed no significant difference between the baseline and 4th week values in both groups (Group I, p = 0.506 and p = 0.070 consecutively) (Group II, p = 0.810 and p = 0.823 consecutively). OSDI scores were found to be significantly increased in group I (21.8 ± 4.2 vs 23.1 ± 4.6, p = 0.020) and remained unchanged in group II (20.5 ± 7.0 vs 20.7 ± 7.0, p = 0.805)., Conclusions: Short-term solifenacin succinate treatment has no effect on the Schirmer I test results and TBUT, but ocular surface symptoms appeared to be exacerbated in respect with increased OSDI scores. However, the clinical significance needs to be further evaluated with larger studies.
