Background: Central post-stroke pain (CPSP) is a type of neuropathic pain caused by dysfunction in the spinothalamocortical pathway. However, no animal studies have examined comorbid anxiety and depression symptoms. Whether the typical pharmacological treatments for CPSP, which include antidepressants, selective serotonin reuptake inhibitors (SSRIs), and anticonvulsants, can treat comorbid anxiety and depression symptoms in addition to pain remains unclear? The present study ablated the ventrobasal complex of the thalamus (VBC) to cause various CPSP symptoms. The effects of the tricyclic antidepressants amitriptyline and imipramine, the SSRI fluoxetine, and the anticonvulsant carbamazepine on pain, anxiety, and depression were examined., Results: The results showed that VBC lesions induced sensitivity to thermal pain, measured using a hot water bath; mechanical pain, assessed by von Frey test; anxiety behavior, determined by the open-field test, elevated plus-maze test, and zero-maze test; and depression behavior, assessed by the forced swim test. No effect on motor activity in the open-field test was observed. Amitriptyline reduced thermal and mechanical pain sensitivity and anxiety but not depression. Imipramine suppressed thermal and mechanical pain sensitivity, anxiety, and depression. Fluoxetine blocked mechanical but not thermal pain sensitivity, anxiety, and depression. However, carbamazepine did not affect pain, anxiety, or depression., Conclusion: In summary, antidepressants and SSRIs but not anticonvulsants can effectively ameliorate pain and comorbid anxiety and depression in CPSP. The present findings, including discrepancies in the effects observed following treatment with anticonvulsants, antidepressants, and SSRIs in this CPSP animal model, can be applied in the clinical setting to guide the pharmacological treatment of CPSP symptoms.

Background: Efforts to develop less heterogeneous, more clinically useful diagnostic categories for depressive disorders include renewed interest in the concept of melancholia (Mel). However, clinical or biological differentiation of Mel from other (nonMel) episodes of depression has been questioned, and it remains unclear whether pharmacological responses proposed to be characteristic of Mel are supported by available research., Methods: We carried out a systematic review seeking treatment trials reports comparing Mel and nonMel depressed subjects for meta-analyses of their differences in responses (a) to antidepressants overall, (b) to tricyclic (TCAs) or serotonin-enhancing agents (serotonin reuptake inhibitors/serotonin-norepinephrine reuptake inhibitors) and (c) with placebo treatment., Results: We identified 25 trials in 16 reports comparing 2597 Mel with 5016 nonMel subjects. Overall, responses to antidepressant treatment did not differ between Mel (39.4%) and nonMel (42.2%) subjects. However, all subjects responded better to TCAs (50.6%) than SRIs (30.0%; p <0.0001). Mel subjects also responded less well with placebo, but also were significantly more severely depressed at intake., Conclusions: Antidepressant responses were similar in Mel and nonMel depressed patients. Mel subjects responded 25% less with placebo but were more severely depressed initially, and there was preferential response to TCAs in both Mel and nonMel subjects. The findings provide little support for proposed differences in responses to particular treatments among Mel versus nonMel depressed patients, and underscore the need to match for illness severity in making such comparisons.

Osteoporotic fractures are associated with major morbidity and mortality, particularly among older age groups. In recent decades, selective serotonin reuptake inhibitors (SSRI) antidepressants have been linked to reduced bone mineral density and increased risk of fragility fracture. However, up to one-third of antidepressant prescriptions are for classes other than SSRIs. Older patients, who are particularly vulnerable to osteoporosis and its clinical and psychosocial consequences, may be prescribed non-SSRI antidepressants preferentially because of increasing awareness of the risks SSRIs pose to bone health. However, to date, the skeletal effects of non-SSRI antidepressants have not been comprehensively reviewed. In this article, we collate and review the available data and discuss the findings. Based on the current literature, we tentatively suggest that tricyclic antidepressants may increase the risk of fracture via mechanisms other than a direct effect on bone mineral density. The risk is apparently confined to current users only and is greatest in the earliest stage of treatment, diminishing thereafter. There is, as yet, insufficient data to conclusively determine the effects of other antidepressant classes on bone. Judicious prescribing of antidepressants among higher risk groups necessitates a thorough review of the individual's risk factors for osteoporosis as well as attention to their falls risk. Further longitudinal, rigorously controlled studies are needed to answer some of the remaining questions on the effects of non-SSRI antidepressants on bone and the mechanisms by which they are exerted.

Through unintentional discovery, monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants (TCAs) were the first antidepressant classes to be used clinically and have been widely available for over half a century. From the 1950s to the 1980s, these two classes of antidepressants were the sole antidepressant tools available to psychiatrists. With the advent of the selective serotonin reuptake inhibitors (SSRIs) in the 1980s and 1990s, the prescribing of the MAOIs and TCAs has fallen significantly worldwide. In this chapter, we take a closer look at the arc of MAOI discovery and clinical use, and how these two classes of drugs compare to each other. This is important because relatively few studies compare these older classes of drugs to the newer classes of antidepressants. Finally, we argue that TCAs, and particularly MAOIs, should continue to play an important role in the modern treatment of depression, especially in the treatment-resistant patient.

Aim: To compare pharmacogenetic test predictions with self-reported treatment experience and side effect tolerability among patients with depression taking psychotherapeutic medications., Methods: Subjects completed a survey recalling medication effectiveness and side effects and then underwent pharmacogenetic testing., Results: Our 15 gene pharmacogenetic panel predicted efficacy (p < 0.001) but did not predict side effect tolerability (p = 0.70) in a group of 352 patients. The pharmacogenetic panel and reported efficacy corresponded 60% of the time and medication tolerability agreed 71% of the time., Conclusion: Pharmacogenetic testing may be a useful adjunct to predict efficacy of medications used to treat depression.

The efficacy of modern antidepressants is largely related to their ability to enhance neurotransmission of serotonin. The medicines with serotonergic properties include trazodone, which is intermediate between tricyclic antidepressants with their powerful antidepressive effect and selective serotonin reuptake inhibitors, as first-line agents in the treatment of depression and anxiety disorders. The value of trazodone for clinical practice is determined by the effective elimination of the symptoms of major depressive disorder in combination with good tolerability, including in elderly patients. Among the advantages of trazodone is the absence of such undesirable effects as sexual dysfunction and weight gain. Trazodone has significant hypnotic and anxiolytic properties, which gives it special meaning in the treatment of depression, combined with insomnia and anxiety. It is emphasized that the beneficial effect of trazodone on sleep should not prevent its main use as a drug for treating major depressive disorder regardless of whether depression is accompanied by insomnia or not.

Dispersive liquid-liquid microextraction was combined with acetonitrile stacking in capillary electrophoresis for the identification of three selective serotonin reuptake inhibitors (citalopram, fluoxetine, and fluvoxamine) in human fluids such as urine and plasma. Parameters that affect the extraction and stacking efficiency, such as the type and volume of the extraction and disperser solvent, extraction time, salt addition for dispersive liquid-liquid microextraction, and sample matrices, pH, and concentration of the separation buffer for stacking, were investigated and optimized. Under optimum conditions, the enrichment factors were in the range of 1195-1441. Limits of detection ranged from 1.4 to 1.7 nM for the target analytes. Calibration graphs displayed satisfied linearity with R 2 greater than or equal to 0.9978, and relative standard deviations of the peak area analysis were in the range of 2.9-5.0% (n = 3). The recoveries of all tricyclic antidepressant drugs from urine and plasma were in the range of 77-117 and 79-106%, respectively. The findings of this study show that dispersive liquid-liquid microextraction acetonitrile-stacking capillary electrophoresis is a rapid and convenient method for identifying tricyclic antidepressant drugs in urine and plasma., (© 2016 WILEY-VCH Verlag GmbH & Co.

Aims: The aim of the study was to perform a systematic review and meta-analysis to determine the association between antidepressants use and risk of myocardial infarction (MI), and whether this association differs between tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs)., Methods: A PubMed/MEDLINE search was conducted for studies published up to December 2013. Included studies were evaluated for publication bias and heterogeneity. Depending on the presence of heterogeneity, a random or fixed effects model was used to identify the pooled relative risk (RR) with 95% confidence intervals (CIs). Cumulative meta-analysis, subgroup and sensitivity analyses were also performed. All analyses were performed using comprehensive meta-analysis software., Results: Fourteen (five cohort and nine case-control) studies were included. There was heterogeneity among the studies (P heterogeneity = 0.02; I (2) = 68%) but no publication bias (Begg's P = 0.30 and Egger's P = 0.45). Antidepressants use significantly increases the risk of myocardial infarction (MI) (RR = 2.03; 95% CI = 1.30-3.18; P < 0.01). On subgroup analysis by study design, cohort studies show significant positive association (RR = 2.16; 95% CI = 1.42-3.29; P < 0.01), but not case-control studies (RR = 2.47; 95% CI = 0.69-8.90; P = 0.17). Sensitivity analysis and cumulative meta-analysis confirmed the stability of results. TCAs users are having 36% increased risk of MI after excluding one outlier (RR = 1.36; 95% CI = 1.10-1.67; P < 0.01), but SSRIs showing no association (RR = 0.84; 95% CI = 0.57-1.22; P = 0.35)., Conclusions: We found evidence that the use of antidepressants was associated with elevated risk of MI. Further research is needed to identify the underlying biological mechanisms.

As the most common psychiatric symptom, depression represents a subject of high interest for the medical community. Background/Objectives: International guidelines consider selective serotonin reuptake inhibitors (SSRIs) the first-line treatment of depression. Although having better efficacy and tolerability in comparison to tricyclic antidepressants or monoamine oxidase inhibitors, the diversity and potential severity of adverse effects and interactions manifested by SSRIs, combined with the frequency of prescriptions, lead to the necessity of evaluating real-world data. The aim of this study was to identify and evaluate the drug interactions reported in EudraVigilance (EV) for the six SSRIs representatives that are authorized in Europe: fluoxetine (FXT), fluvoxamine (FVM), citalopram (CIT), escitalopram (ESC), paroxetine (PAR) and sertraline (SER). The entire class of SSRIs was examined as a comparator to identify whether one of the representatives was more prone to reporting. Methods: Descriptive analysis and disproportionality analysis were conducted on data extracted from the EV database. Results: A total of 326,450 adverse reactions (ADRs) were reported for the SSRIs group. Approximately a quarter of these (n = 83,201; 25.46%) were reported for SER and 22.37% (n = 73,131) for PAR. Of the total ADRs reported, 2.12% (n = 6925) represent preferred terms related to drug-drug interactions (DDIs): SER (n = 1474; 22.37%), CIT (n = 1272, 19.86), and FXT (n = 1309, 19.83%). Specific ADRs related to inhibitory activity represent 0.98%, and for potentiating activity, 1.89%. Conclusions: Although representing a small value of the total ADRs, DDIs may be related to severe outcomes. Awareness should be raised for this category of ADRs that can be reduced by the joined efforts of physicians and pharmacists. [ABSTRACT FROM AUTHOR]

Micronutrient deficiencies and excesses are closely related to developing and treating depression. Traditional and effective antidepressants include tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs), and lithium. There is no consensus on the fluctuation of zinc (Zn2+), magnesium (Mg2+), calcium (Ca2+), copper (Cu2+), iron (Fe2+), and manganese (Mn2+) ion levels in depressed individuals before and after therapy. In order to determine whether there were changes in blood and cerebrospinal fluid (CSF) levels of these ions in depressed patients compared with healthy controls and depressed patients treated with TCAs, SSRIs, or lithium, we applied a systematic review and meta-analysis. Using the Stata 17.0 software, we performed a systematic review and meta-analysis of the changes in ion levels in human samples from healthy controls, depressive patients, and patients treated with TCAs, SSRIs, and lithium, respectively. By searching the PubMed, EMBASE, Google Scholar, Web of Science, China National Knowledge Infrastructure (CNKI), and WAN FANG databases, 75 published analyzable papers were chosen. In the blood, the levels of Zn2+ and Mg2+ in depressed patients had decreased while the Ca2+ and Cu2+ levels had increased compared to healthy controls, Fe2+ and Mn2+ levels have not significantly changed. After treatment with SSRIs, the levels of Zn2+ and Ca2+ in depressed patients increased while Cu2+ levels decreased. Mg2+ and Ca2+ levels were increased in depressed patients after Lithium treatment. The findings of the meta-analysis revealed that micronutrient levels were closely associated with the onset of depression and prompted more research into the underlying mechanisms as well as the pathophysiological and therapeutic implications.

BACKGROUND: Antidepressants are increasingly used in children for various psychiatric disorders but also for sleep disorders such as insomnia; however, it is currently unknown how many children undergoing polysomnography (PSG) are taking anti-depressants. The aims were: to determine the frequency of use of antidepressants in paediatric patients referred for PSG, to identify the most common antidepressants used, to investigate the reasons for their use, and to analyse the PSG parameters found in children taking antidepressants. METHOD: An observational cross-sectional retrospective chart review of all children undergoing PSG at Seattle Childrens Hospital from 6/14/2020 to 12/8/2022 was carried out. Clinical features (such as diagnosis, especially psychiatric), sleep disorders (such as insomnia and restless sleep), and class of antidepressant used [selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCA), or atypical antidepressants], and PSG parameters were collected for further analysis. RESULTS: Among 3,371 patients who underwent PSG during the study, 367 children were selected who were taking one antidepressant only (154 boys and 213 girls, mean age was 13.7 ± years 3.69). A significantly decreased sleep stage N3 was found in girls, who were older than boys. Children with insomnia had longer sleep latency than children without, but more N3. There was a prolonged rapid eye movement (REM) sleep latency in children with attention-deficit/hyperactivity disorder and children with autism. REM latency was longer and REM percentage smaller in children taking SNRIs. Periodic leg movement index ≥ 5/hour was found in a higher number of children taking SSRIs or SNRIs (24.9%) than in subjects taking TCA or atypical antidepressants (13.3%) (chi-square 5.29, p = 0.013). CONCLUSIONS: Child and adolescent psychiatrists should question about the effects on sleep (both positive and negative) after initiating therapy with antidepressant medications.

Antidepressants are widely used in neurological practice, and their use in stroke, Alzheimer's disease, depression with cognitive impairment, Parkinson's disease, multiple sclerosis, chronic back pain and chronic migraine is discussed. Antidepressants are used in the presence of severe depressive symptoms, which are observed in 20–30% of neurological patients. The effect of antidepressants is higher in case of combination with recurrent depression. Presence of episodes of depression before the development of a neurological disease, history of effectiveness of antidepressants, hereditary burden of affective disorders, characteristic daily dynamics of symptoms with typical impaired sleep architecture indicate the likelihood of a combined affective disorder. Final establishment of a psychiatric diagnosis is possible with a consultation of a neurological patient by a psychiatrist, but in clinical practice this is realistic only in a small number of patients. The most commonly used antidepressants are selective serotonin reuptake inhibitors, selective serotonin and norepinephrine reuptake inhibitors, tricyclic antidepressants in low or medium doses, the duration of their administration is usually at least 3-6 months. In neurological diseases, the effectiveness of only some drugs has been noted, many antidepressants have not been studied in neurological diseases, but this does not exclude their effectiveness. When prescribing antidepressants, it is necessary to take into account possible drug interactions and avoid those combinations that may cause adverse reactions. It is advisable to use antidepressants in complex therapy in combination with an educational program, cognitive behavioral therapy and kinesiotherapy. Many questions regarding the efficacy and safety of treatment, the choice of the optimal antidepressant, its dosage and duration of use require further study.

Study Design: Retrospective cohort. Purpose: To determine (1) the effects of serotonin reuptake inhibitors in pseudarthrosis rates after anterior cervical decompression and fusion (ACDF) and (2) to identify patient-reported outcome measures in patients taking serotonin reuptake inhibitors. Overview of Literature: Recent literature suggests that selective serotonin reuptake inhibitors (SSRIs) may inhibit fracture healing via downregulation of osteoblast differentiation. Spinal fusion supplementation with osteoblast-rich substances enhances spinal fusion, thus SSRIs may be detrimental. Methods: Patients with 1-year postoperative dynamic cervical spine radiographs following ACDF were grouped into serotonin reuptake inhibitor prescriptions (SSRI, serotonin-norepinephrine reuptake inhibitor [SNRI], or tricyclic antidepressant [TCA]) and no prescription (atypical antidepressant or no antidepressant). Pseudarthrosis was defined as =1 mm interspinous process motion on dynamic radiographs. Logistic regression models were controlled for confounding to analyze pseudarthrosis rates. Alpha was set at p - values of <0.05. Results: Of the 523 patients who meet the inclusion criteria, 137 (26.2%) were prescribed an SSRI, SNRI, or TCA. Patients with these prescriptions were more likely to have pseudarthrosis (p =0.008) but not a revision surgery due to pseudarthrosis (p =0.219). Additionally, these patients had worse 1-year postoperative mental component summary (MCS)-12 (p =0.015) and Neck Disability Index (NDI) (p =0.006). The multivariate logistic regression analysis identified SSRI/SNRI/TCA use (odds ratio [OR], 1.82; 95% confidence interval [CI], 1.11-2.99; p =0.018) and construct length (OR, 1.91; 95% CI, 1.50-2.44; p <0.001) as pseudarthrosis predictors. A SSRI/SNRI/TCA prescription was a revision surgery predictor due to adjacent segment disease on univariate analysis (OR, 2.51; p =0.035) but not on multivariate logistic regression analysis (OR, 2.24; p =0.10). Conclusions: Patients taking serotonin reuptake-inhibiting antidepressants are at increased risk of worse postoperative outcome scores, including NDI and MCS-12, likely due to their underlying depression. This may contribute to their greater likelihood of having adjacent segment surgery. Additionally, preoperative use of serotonin reuptake inhibitors in patients undergoing an ACDF is a predictor of radiographic pseudarthrosis but not pseudarthrosis revision. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To evaluate and categorize the survival benefit of tricyclic antidepressants (TCAs) in lung cancer patients based on systematic computational drug repositioning data. METHODS: Data were retrospectively extracted from the medical records of non-small cell lung cancer (NSCLC) patients from the University of Cincinnati Cancer Medical Center database. Patients receiving antidepressants during their course of anti-cancer treatment were compared with those without antidepressants. Data were analyzed using Kaplan–Meier survival curves with the log-rank test, and overall survival (OS) was calculated from the date of diagnosis until last follow-up or death. RESULTS: The median OS at 2 and 5 years for patients on antidepressants was 20.3 months (54.7% and 42%) vs 44.3 months (47.6% and 43.2%), which was not significant. The median OS for patients receiving TCAs, selective serotonin reuptake inhibitors, and other antidepressants was 3.17 months, 31.33 months, and 18.50 months, respectively. CONCLUSION: We found no significant survival benefit for TCA use in combination with anti-cancer agents in NSCLC patients.

Background: Continuous use of antidepressants can relieve depressive symptoms and prevent recurrence in people with depression; however, many studies have reported low drug compliance rates. This study aimed to investigate the relationship between the type of initial antidepressants and treatment adherence in outpatients with new onset depression.Methods: This was a retrospective cohort study using National Health Insurance claim data for services provided in 2012. We examined data from 142,336 individuals aged 18 years or older, who were continuously enrolled in treatment after a new episode of depression, and had initiated antidepressant treatment. A new diagnosis of depression, is defined as a first reported diagnosis of depression in the preceding five years. Adherence was operationally defined as the antidepressant being dispensed to the patient at least 80% of the time during the first three- and six-month treatment periods. To investigate the relationship between the initial type of antidepressants and treatment adherence, we estimated adjusted odds ratios and 95% confidence intervals using logistic regression analysis, adjusting for socio-demographic and health care utilization characteristics.Results: A statistically significant association was found between initial antidepressant type and adherence in the first three- and six-month treatment periods for employed and self-employed patients newly diagnosed with major depression. In addition, patients with starting prescriptions for tricyclic antidepressants had significantly lower adherence compared to selective serotonin reuptake inhibitors.Limitations: This study used national insurance data; therefore, only variables on the claim form were available, and psychological and environmental factors were not considered.Conclusions: This was the first study to demonstrate the relationship between initial antidepressant type and treatment adherence among Korean outpatients with new onset depression.

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder associated with significant disease burden. This American Gastroenterological Association Guideline is intended to support practitioners in decisions about the use of medications for the pharmacological management of IBS with predominant diarrhea (IBS-D) and is an update of a prior technical review and guideline. The Grading of Recommendations Assessment, Development and Evaluation framework was used to assess evidence and make recommendations. The technical review panel prioritized clinical questions and outcomes according to their importance for clinicians and patients and conducted an evidence review of the following agents: eluxadoline, rifaximin, alosetron, loperamide, tricyclic antidepressants, selective serotonin reuptake inhibitors, and antispasmodics. The guideline panel reviewed the evidence and used the Evidence-to-Decision Framework to develop recommendations. The panel agreed on 8 recommendations for the management of patients with IBS-D. The panel made conditional recommendations for eluxadoline, rifaximin, alosetron, (moderate certainty), loperamide (very low certainty), tricyclic antidepressants, and anstispasmodics (low certainty). The panel made a conditional recommendation against the use of selective serotonin reuptake inhibitors (low certainty). [ABSTRACT FROM AUTHOR]

• Antidepressant use was associated with an overall decreased risk of ovarian cancer. • The risk reduction was larger among postmenopausal women and long-term users. • The effect was most prominent for serous ovarian cancers. • Selective serotonin reuptake inhibitors showed the strongest risk reduction. • Oral contraceptive use and hormone replacement therapy both modified the association. Given that the evidence regarding the link between antidepressant use and ovarian cancer risk is equivocal, we investigated this research question by conducting two nationwide nested case-control studies among the Danish and Swedish populations. Altogether, 14,121 women with epithelial ovarian cancer (30–84 years old) (Denmark: 8976 diagnosed 2000–2019, Sweden: 5145 diagnosed 2010–2018) were randomly age-matched with 564,840 female controls (359,040 from Denmark, and 205,800 from Sweden) using risk set sampling. We used conditional logistic regression to estimate odds ratios (OR) with 95 % confidence intervals (CI) and combined the estimates based on the fixed-effect assumption. We also investigated potential effect modification by well-established risk factors for ovarian cancer. Antidepressant use was associated with an overall reduced risk of ovarian cancer (OR = 0.92, 95%CI: 0.88–0.96), and that reduction was more pronounced in postmenopausal women and long-term users. The effect was most pronounced for serous ovarian tumors (OR = 0.90, 95%CI: 0.86–0.95) but was also observed in other subtypes, although not statistically significant. Among different types of antidepressants, selective serotonin reuptake inhibitors in general and citalopram in particular exhibited a noteworthy reduction in ovarian cancer risk (OR = 0.89, 95%CI: 0.82–0.96). Additionally, use of oral contraceptives and hormone replacement therapy individually modified the association between antidepressant use and ovarian cancer risk. Use of an antidepressant was associated with a slight, but statistically significant, decrease in ovarian cancer risk. Given the morbidity and mortality associated with ovarian cancer, and increasing use of antidepressants, these findings may be of significance to cancer prevention and should be studied in more detail mechanistically.

Mental health disorders are independent risk factors for adverse perinatal and neonatal outcomes. It is estimated that 20% of women may experience symptoms of mental health disorders during or following pregnancy. It is important that obstetricians recognize the presentation of these symptoms and follow pathways for managing these conditions. This article utilizes case vignettes to describe the epidemiology, role of the multi-disciplinary team, clinical presentation, and management of common perinatal mental health disorders both from the obstetric and psychiatric view point. Indications and duration of psychotropic medications including side effects are also discussed as well as safety in pregnancy and lactation. [ABSTRACT FROM AUTHOR]

Objective: In this study, we aimed to evaluate the relationship between laboratory electrolyte disturbances and drugs taken in poisoning cases who applied to the Emergency Department and took drugs for suicidal purposes. Materials and Methods: This study is a retrospective study. Patients aged 18 years and older who were diagnosed with drug poisoning in the Adult Emergency Clinic of Okmeydanı Training and Research Hospital Emergency Medicine Clinic were included in the study. Data analysis was done in SPSS 15.0 program. The significance level was taken as p<0.05. Results: 162 patients were included in the study. The mean age of the patients was 27 (range 18-61) years. Thirty-four (20.99%) of the patients were male. Considering the frequency of the drugs taken, 34 (21.1%) of the patients had NSAIDs (most common), 33 (20.5%) had paracetamol and/or its compounds, 29 (17.7%) had SSRI, had TCA, 149 (55.3%) had other drugs. It was observed that the serum Na values of the patients who took and did not take high-dose NSAIDs changed statistically (p=0.000). The laboratory test results of the patients who took and did not take these drugs were compared, and no statistically significant difference was found (p>0.05). Conclusion: According to our suicidal study findings, the amount of drugs taken by our patients is not correlated with their blood levels. Although more than half of our patients have taken toxic doses of the drugs, most of the poisonings are mild and our results can not be generalized to severe poisoning cases. [ABSTRACT FROM AUTHOR]

To analyse the current therapeutic options for patients with premature ejaculation (PE) and highlight their mechanism(s) of action, effectiveness, advantages and limitations. A literature search was conducted using the PubMed database searching for articles exploring different PE treatment modalities. A Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) approach was used to report the results of the literature search. A total of 149 articles were included in this review. The currently available treatment methods for PE include behavioural therapy, local anaesthetics, tricyclic antidepressants, selective serotonin reuptake inhibitors, and selective phosphodiesterase inhibitors. Most PE treatments are either experimental or used off-label. New treatments are certainly warranted to overcome this exasperating sexual dysfunction.

Objectives: Although many antidepressants are available, they are not always used appropriately. For appropriate use of antidepressants, the old concept of a linear dose–response relationship, in which the dose is linearly increased to achieve a sufficient antidepressant effect, should be reconsidered. Furthermore, there is ongoing debate on the safe and appropriate use of antidepressants in patients with bipolar depression. Antidepressants may be used under certain conditions in patients with bipolar depression. These neglected—but not negligible—aspects of antidepressants have been discussed herein. Methods: A narrative qualitative review Results: Dose–response relationships of antidepressants such as selective serotonin reuptake inhibitors (SSRIs) are not linear. They may be bell‐shaped, with efficacy initially increasing with an increase in dose but decreasing when the dose is increased beyond a certain point. Despite using international diagnostic criteria, uncertainty remains on whether operationally diagnosed depression is latent bipolar I depression, latent bipolar II depression, or true depression. Furthermore, operationally diagnosed bipolar II depression may be latent bipolar I depression, true bipolar II depression, or depression with false hypomanic episodes. Manic/hypomanic switches are most likely to occur in patients receiving tricyclic antidepressants, followed by those receiving serotonin and noradrenaline reuptake inhibitors and SSRIs, in that order. Also, these switches are most likely to occur in patients with bipolar I depression, followed by those with bipolar II depression and true depression, in that order. Conclusions: Considering the diagnostic subtype of bipolar depression and antidepressant properties may help to determine the optimal treatment strategy. [ABSTRACT FROM AUTHOR]

A biopsychosocial and lifestyle approach should be used when managing depression. Many patients seen in primary care do not require drug therapy. Evidence-based treatments such as psychological therapies and antidepressant drugs are effective for depression. All patients should receive education about depression. Shared decision making with the patient is critical if an antidepressant is prescribed. The choice of antidepressant depends on its efficacy and tolerability, the depressive presentation, patient preference and drug interactions. [ABSTRACT FROM AUTHOR]

Background: Previous studies have suggested an association between taking antidepressants and dental implant failure. This study aimed to investigate the association of different antidepressant classes with dental implant failure.Methods: This retrospective study included patients that received dental implants at the University of Florida from 2011 to 2016. The variables of implant failure, antidepressant use and classes (selective serotonin reuptake inhibitors [SSRI], serotonin-norepinephrine reuptake inhibitors [SNRI], tricyclic antidepressants [TCA], atypical antidepressants [AA], and monoamine oxidase inhibitors [MAOI]), age, sex, smoking, mild systemic diseases, and implant location were obtained from patients' records. Odds ratio (OR) and confidence interval (CI) of implant failure in patients taking different antidepressant classes, in relationship to non-antidepressant users, were estimated, and the influence of multiple variables on implant failure were investigated.Results: A total of 771 patients and 1,820 implants were evaluated. The statistically significant predictors for implant failure included smoking (OR = 5.221), use of antidepressants (OR = 4.285), posterior maxilla location (OR = 2.911), mild systemic disease (OR = 2.648), and age (OR = 1.037) (P <0.05). The frequency of implant failure was 33.3% in TCA users, 31.3% in SNRI users, 6.3% in SSRI users, 5.2% in Atypical antidepressant users, and 3.9% in non-users. Significant associations were observed between the use of SNRI (OR: 11.07; 95% CI: 3.265 to 33.82) and TCA (OR: 12.16; 95% CI: 1.503 to 71.58) and implant failure (P <0.05).Conclusions: Users of antidepressants were at higher risk of implant failure than non-users. Patients taking SNRI and TCA were at the highest risk of implant loss, when compared with non-users. Conclusions about TCA, however, are based on a limited number of cases. [ABSTRACT FROM AUTHOR]

Depression is a frequent complication of stroke and develops in about one third of survivors. It degrades the course of poststroke neurological impairments, increases the physical helplessness of patients, and decreases their quality of life, significantly reducing the efficacy of therapeutic and rehabilitation measures and increasing the risk of lethal outcomes. Antidepressants eliminate or decrease the symptoms of depression, promote reductions in neurological disorders, improve cognitive functions and patient's overall status, increase the efficacy of treatment and rehabilitation, decrease the risk of repeat stroke, and decrease lethality. Preference in the treatment of poststroke depression is given to selective serotonin reuptake inhibitors; data have been obtained on the efficacy of other contemporary antidepressants, as well as tricyclic antidepressants. Unresolved aspects of this problem requiring further suitably designed controlled studies include the tolerance of antidepressants by elderly patients, selection of the appropriate drugs, and choice of treatment duration.

Patients with hypothyroidism frequently have associated depressive disorder which may require antidepressant therapy. The clinical significance of drug–drug interaction between replacement thyroid hormones and antidepressants has remained controversial. Against this background, we present a case report of a suspected clinically significant drug–drug interaction between levothyroxine and an antidepressant in a patient with hypothyroidism and depressive disorder. A relevant patient's details were retrieved from the case notes. Extensive literature search of drug–drug interaction between replacement thyroid hormones and antidepressants was done using databases such as PubMed, PubMed Central, Google Scholar, and Embase. A 25-year-old woman was recently diagnosed with primary hypothyroidism associated with a major depressive disorder. She was stabilized on levothyroxine 100 μg daily with clinical and biochemical euthyroidism 2 months later. Due to lack of significant improvement in her depressive state, she was commenced on paroxetine 20 mg nocte. Subsequently, the depressive symptoms remarkably subsided, but the symptoms of hypothyroidism recurred. Supervised and regular intake of levothyroxine was confirmed. The patient did not ingest supplements containing biotin, calcium, iron, magnesium, and she was not on other medications. Levothyroxine was stored as per product insert at 20°C–25°C (68°F–77°F), and it was protected from light and moisture. After ruling out these confounders, the dose of levothyroxine was gradually increased at 4-weekly interval to 300 μg daily until biochemical and clinical euthyroidism was achieved, though with suspicion of thyroid hormone resistance. On re-appearance of hypothyroidism symptoms even at such a high dose of levothyroxine, drug–drug interaction between levothyroxine and paroxetine was suspected, leading to the replacement of paroxetine with amitriptyline. Biochemical and clinical euthyroidism was subsequently achieved, and the patient even began to complain of thyrotoxic symptoms, until levothyroxine dose was gradually titrated downward to 100 μg daily to achieve and maintain clinical and biochemical euthyroidism. Levothyroxine may be better co-administered with tricyclic antidepressants than selective serotonin reuptake inhibitors (SSRIs) because of the suspected clinically significant drug–drug interaction demonstrated between levothyroxine and paroxetine (SSRI).

Besides the memory impairment, Alzheimer’s disease (AD) is often complicated by neuropsychiatric symptoms also known as behavioral and psychological symptoms of dementia, which occur in one-third of patients at an early stage of the disease. Although the relationship between depressive disorders and AD is debated, the question if depression is a prodromal symptom preceding cognitive deficits or an independent risk factor for AD is still unclear. Moreover, there is growing evidence reporting that conventional antidepressants are not effective in depression associated with AD and, therefore, there is an urgent need to understand the neurobiological mechanism underlying the resistance to the antidepressants. Another important question that remains to be addressed is whether the antidepressant treatment is able to modulate the levels of amyloid-β peptide (Aβ), which is a key pathological hallmark in AD. The present review summarizes the present knowledge on the link between depression and AD with a focus on the resistance of antidepressant therapies in AD patients. Finally, we have briefly outlined the preclinical and clinical evidences behind the possible mechanisms by which antidepressants modulate Aβ pathology. To our opinion, understanding the cellular processes that regulate Aβ levels may provide greater insight into the disease pathogenesis and might be helpful in designing novel selective and effective therapy against depression in AD.

The irritable bowel syndrome (IBS) is a highly frequent functional gastrointestinal disorder. A large part of the decrease in quality of life and the increase in economic burden associated with IBS stems from its widely variable nature, the multiplicity of available treatments, and the heterogeneity of the clinical results upon them. Current IBS therapy contemplates modifications in diet and physical activity, mental health care, and pharmacotherapy. The latter includes, among others, the use of antispasmodics, probiotics, antibiotics, and antidepressants (AD), especially selective serotonin reuptake inhibitors and tricyclic antidepressants. These are a particularly attractive alternative, as they may simultaneously manage the disease's psychological and physiological factors, such as those directly related with neurotransmission and intestinal local signaling. Although the theoretical foundation is rich, available clinical experience has highlighted the nuances and limitations of their use in practice. In the future, further research is needed to elucidate the ideal mode of prescription, as well as the specific AD with better balance between benefits and adverse effects, and the real relationship between the symptoms of IBS proper and depressive-anxious symptoms. Clarification of these aspects would serve as an invaluable orientation for the development of individualized treatment plans for each patient with IBS. This review explores current basic and clinical pharmacological aspects concerning the use of AD in the treatment of IBS. [ABSTRACT FROM AUTHOR]

Background: Both depression and use of antidepressants have been reported to be risk factors for stroke, but results from the literature are still not conclusive regarding the risk attributable to antidepressants rather than to the underlying disease. Objective: To estimate the risk of incident stroke associated with use of antidepressants, a meta-analysis was performed. Methods: PubMed, Medline, Cochrane, ProQuest, Scopus, and bibliographies of articles were searched up to September 2018. The final meta-analysis included 31 observational studies. STROBE statement-checklist and GRADE guidelines were used for quality assessment. Results: The random-effects meta-analysis on the association between use of any antidepressant and risk of any stroke resulted in meta-risk ratio (RR) of 1.41 (95% CI 1.13–1.69, I2 = 93, 7%). The pooled estimate for selective serotonin reuptake inhibitors (SSRIs) resulted in a meta-RR of 1.41 (95% CI 1.13–1.69, I2 = 94, 5%) and for tricyclic antidepressants (TCAs) of 1.08 (95% CI 0.93–1.22, I2 = 0%). SSRI users displayed a higher risk of ischemic (1.57, 95% CI 1.06–2.09, I2 = 96.4%) than hemorrhagic stroke (1.34, 95% CI 1.15–1.53, I2 = 72.9%). Meta-RRs were lower for TCA, although with smaller heterogeneity (ischemic 1.22, 95% CI 0.97–1.46; I2 = 0%; hemorrhagic: 1.00, 95% CI 0.83–1.18, I2 = 0%). Restricting to studies on depressed individuals, both SSRI and TCA remained associated with an increased risk of any stroke type (meta-RR for SSRI: 1.27, 95% CI 1.11–1.43, I2 = 76.6%; meta-RR for TCA: 1.21 (95% CI 1.02–1.40, I2 = 47, 3%). Conclusions: Despite the high heterogeneity, these results demonstrate that even after adjusting for depression, use of antidepressants retains an independent increased risk of stroke.

The contribution of depression to the pathogenesis of cardiovascular disease includes autonomic disturbances, endothelial dysfunction, inflammation, smoking, sedentary lifestyle, carbohydrate craving, and impaired fibrinolysis. There is evidence that serotonergic antidepressants (selective serotonin reuptake inhibitors and serotonin and noradrenaline reuptake inhibitors) restore the fibrinolytic profile. Contrary to common belief, such antidepressants do not affect platelet aggregation induced by adenosine diphosphate or adrenaline but reduce platelet adhesion to collagen. Since platelet collagen receptor glycoprotein VI binds to fibrin, it is possible that fibrinolytic properties of serotonergic antidepressants could impair platelet adhesion to collagen. The profibrinolytic and antiplatelet properties of serotonergic antidepressants help explain the increased risk of gastrointestinal, intracranial, and surgical bleeding in patients using these medications. Studies evaluating the impact of antidepressants on thrombotic and cardiovascular risk have yielded contradictory results. Corroborating the hypothesis that serotonergic antidepressants have profibrinolytic and antiplatelet properties, some authors showed that these medications prevent both cardiovascular and thromboembolic events. Others showed an increased risk of ischemic stroke, cardiac events and thromboembolic disease. Silent brain infarction may present in some elders with depressive symptoms, so it is presumed that antidepressants are prescribed for subclinical stroke patients. Another explanation for the increased risk of cardiovascular and thromboembolic events reported by some authors in individuals taking antidepressants includes antidepressant side effects such as sedation and weight gain and depression comorbidities such as anxiety, obesity and hyperhomocysteinemia. In conclusion, we suggest that serotonergic antidepressants be considered weak anticoagulants. We also suggest that depressed patients with comorbidities increasing the risk of cardiovascular and thromboembolic disease be recommended to follow a balanced diet and engage in physical activity, such as daily walking.

Depression is a common mental disorder that may lead to major mental health problems, and antidepressant drugs have been used as a treatment of choice to mitigate symptoms of major depressive disorders by ameliorating the chemical imbalances of neurotransmitters in brain. Since abusing antidepressant drugs such as selective serotonin reuptake inhibitors and tricyclic antidepressant drugs can cause severe adverse effects, continuous toxicological monitoring of the parent compounds as well as their metabolites using numerous analytical methods appears pertinent. Among them, capillary electrophoresis has been popularly utilized since the method has a lot of advantages viz. using small amounts of sample and solvents, ease of operation, and rapid analysis. This review paper brings a survey of more than 30 papers on capillary electrophoresis of antidepressant drugs published approximately from 1999 until 2018. It focuses on the reported capillary electrophoresis techniques and their applications and challenges for determining antidepressant drugs and their metabolites. It is organized according to the commonly used capillary zone electrophoresis method, followed by non‐aqueous capillary electrophoresis and micellar electrokinetic chromatography, with details on breakthrough findings. Where available, information is given about the background electrolyte used, detector utilized, and sensitivity obtained. [ABSTRACT FROM AUTHOR]

Purpose: The study aimed to fill existing knowledge gaps on the safety of antidepressant drugs (ADs) by estimating the risk of hospitalization for arrhythmia associated with use of selective serotonin reuptake inhibitors (SSRIs) and newer atypical ADs (NAAs) among elderly with previous cardiovascular (CV) events. Methods: The cohort was composed by 199,569 individuals aged ≥ 65 years from five Italian healthcare territorial units who were discharged for cardiovascular outcomes in the years 2008-2010. The 17,277 patients who experienced hospital admission for arrhythmia during follow-up were included as cases. Odds of current ADs use among cases (i.e., 14 days before hospital admission) was compared with (i) odds of current use of 1:5 matched controls (between-patients case-control) and with (ii) odds of previous use during 1:5 matched control periods (within-patient case-crossover). The risk of arrhythmia associated with ADs current use was modelled fitting a conditional logistic regression. A set of sensitivity analyses was performed to account for sources of systematic uncertainty. Results: Current users of SSRIs and NAAs were at increased risk of arrhythmia with case-control odds ratios (OR) of 1.37 (95% confidence interval, CI 1.18 to 1.58) and 1.41 (1.16 to 1.71) and case-crossover OR of 1.48 (1.20 to 1.81) and 1.72 (1.31 to 2.27). An increased risk of arrhythmia was associated with current use of trazodone (NAA) consistently in case-control and case-crossover designs. Conclusions: Evidence that current use of SSRIs and NAAs is associated to an increased risk of arrhythmia among elderly with CV disease was consistently supplied by two observational approaches.
