- Abstract
Cenerimod, a sphingosine-1-phosphate 1 receptor modulator, is in development for the treatment of systemic lupus erythematosus, a disease mainly affecting women of childbearing potential. The effect of cenerimod on the pharmacokinetics (PK) of a combined oral contraceptive (COC, 100 µg levonorgestrel and 20 µg ethinylestradiol (EE)) was investigated. A randomized, double-blind, parallel-group study was performed in 24 healthy male and female subjects. A single oral dose of COC was administered alone and after 35 days of once daily (o.d.) administration of cenerimod 0.5 (n = 10) or 4 (n = 14) mg. Exposure to EE alone or in combination with cenerimod was comparable as reflected by the geometric mean ratios and the respective 90% confidence intervals, while a slight increase in exposure (approximately 10-25%) to levonorgestrel was observed at clinically relevant concentrations of cenerimod. Overall, COC alone or in combination with cenerimod was safe and well tolerated. Two subjects reported one adverse event each (one headache after COC alone, and gastroenteritis in combination with cenerimod 4 mg). In conclusion, cenerimod does not affect the PK of levonorgestrel or EE to a clinically relevant extent. Therefore, COC can be selected as method of contraception during and after cenerimod therapy without the risk of interaction.

- Abstract
Ethnopharmacological Relevance: Eugenia uniflora (Myrtaceae) is a species native to Brazil and has a traditional use in the treatment of inflammation., Aim of the Study: To evaluate the anti-inflammatory and antinociceptive effects, and the involvement of opioid receptors in the antinociceptive activity of extract and fractions from Eugenia uniflora leaves., Materials and Methods: TLC and HPLC were used to characterize the spray-dried extract (SDE) and fractions. In the in vivo assays, Swiss (Mus musculus) mice were used. Carrageenan-induced hind-paw edema and carrageenan-induced peritonitis models were used to determine the anti-inflammatory effect of the extract (50, 100, or 200 mg/kg). Acetic acid-induced writhing, tail-flick, and formalin tests were used to determine the antinociceptive effect of the extract (50, 100, or 200 mg/kg). The aqueous (AqF) and ethyl acetate (EAF) fractions (6.25, 12.5, and 25 mg/kg) were then combined with naloxone to evaluate the involvement of opioid receptors in the antinociceptive activity., Results: In this work, the TLC and HPLC analysis evidenced the enrichment of EAF, which higher concentration of gallic acid (5.29 ± 0.0004 %w/w), and ellagic acid (1.28 ± 0.0002 %w/w) and mainly myricitrin (8.64 ± 0.0002 %w/w). The extract decreased the number of total leukocytes and neutrophils in the peritoneal cavity (p < 0.05), at doses of 100 and 200 mg/kg and showed significant inhibition in the increase of paw edema volume (p < 0.05). The treatment per oral route (doses of 50, 100, and 200 mg/kg) significantly reduced the nociceptive response in acetic acid-induced abdominal writhing (p < 0.05). The effect of the extract on the tail-flick test showed a significant increase in latency time of animals treated at doses of 200 and 100 mg/kg (p < 0.05). The extract and ethyl acetate fraction reduced the nociceptive effect in both phases of formalin at all tested doses. The naloxone reversed the antinociceptive effect of EAF, suggesting that opioid receptors are involved in mediating the antinociceptive activity of EAF of E. uniflora in the formalin test., Conclusion: The current study demonstrates the anti-inflammatory and analgesic activities of water: ethanol: propylene glycol spray-dried extract from E. uniflora leaves using in vivo pharmacological models in mice. Our findings suggest that spray-dried extract and ethyl acetate fraction exhibit peripheral and central antinociceptive activity with the involvement of opioid receptors that may be related to the presence of flavonoids, mainly myricitrin., (Copyright © 2022 Elsevier B.V.

- Abstract
Background: Recent progress in chronic cough management includes controlling cough triggers and hypersensitivity using antitussives. Therefore, we investigated the effects and safety outcomes of antitussives, codeine and levodropropizine, in patients with chronic cough., Methods: We conducted an open-label, randomized comparative trial with newly referred patients with chronic cough. Patients were orally administered codeine (60 mg/day) and levodropropizine (180 mg/day) for 2 weeks. Cough severity, including the visual analog scale (VAS), Cough Symptom Score (CSS), Leicester Cough Questionnaire (LCQ), and safety for each treatment were assessed. The primary outcome was VAS score changes before and after 2 weeks of treatment., Results: Among the 88 participants, 45 and 43 in the codeine and levodropropizine groups, respectively, were included in the analysis. Changes in the VAS score were higher in the codeine group than in the levodropropizine group (35.11 ± 20.74 vs. 19.77 ± 24.83, P = 0.002). Patients administered codeine also had improved CSS (2.96 ± 2.35 vs. 1.26 ± 1.89, P < 0.001) and LCQ (3.28 ± 3.36 vs. 1.61 ± 3.53, P = 0.025) than those administered levodropropizine. Treatment-related adverse events, including drowsiness, constipation, and headaches, were more frequent in the codeine group than in the levodropropizine group. However, no significant differences existed in the adverse events leading to discontinuation., Conclusion: Codeine is an effective and generally well-tolerated antitussive for chronic cough. However, it may induce side effects in some patients. Individual responses and adverse events should be carefully monitored when codeine is used to treat chronic cough., Competing Interests: The authors have no potential conflicts of interest to disclose., (© 2022 The Korean Academy of Medical Sciences.)

- Abstract
Cenerimod is a sphingosine-1-phosphate 1 receptor (S1P
1 R) modulator in phase II development for treatment of systemic lupus erythematosus. Its pharmacokinetics (PKs), pharmacodynamics (PDs), as well as safety and tolerability were investigated in white and Asian subjects to allow for recruitment of Asian patients in future studies. A randomized, double-blind, placebo-controlled parallel-group study was performed in 20 healthy male subjects (n = 10 per ethnicity). A single, oral dose of 4 mg cenerimod or placebo (ratio 8:2) was administered under fasted conditions. The PKs of cenerimod were similar in white and Asian subjects indicated by geometric mean ratios (90% confidence interval) of 0.99 (0.80-1.21) for maximum plasma concentration, 0.96 (0.75-1.24) for area under the plasma concentration-time curve from 0 to infinity, and 1.04 (0.86-1.25) for terminal half-life. Accordingly, the extent and time course of reduction in lymphocyte count (as PD biomarker) were also similar in white and Asian subjects as compared with placebo. As observed for other S1PR modulators, a transient mean (SD) heart rate reduction in white (15.1 (14.8) bpm) and Asian (11.8 (6.16) bpm) subjects was observed following administration of cenerimod. The drug was safe and well-tolerated indicated by occurrence of a single adverse event of chemical conjunctivitis in a white subject that was not suspected as study drug related. In conclusion, the determined absence of any relevant PK or PD differences supports using the same doses of cenerimod in white and Asian patients in upcoming late-phase studies., (© 2020 Idorsia Pharmaceuticals Ltd.

- Abstract
Household products often contain an antimicrobial agent such as biocides, polyhexamethylene guanidine (PHMG), triclosan (TCS), and propylene glycol (PG) as an excipient to dissolve the active ingredients. The skin sensitization (SS) potentials of each of these substances or mixtures of PHMG or TCS with PG have not been investigated through in vitro alternative test methods. The in vitro alternative assay called human Cell Line Activation Test (h-CLAT) served to address these issues. The h-CLAT assay was conducted in accordance with OECD TG 442E. On three independent runs, all the three substances were predicted to be sensitizers according to the SS positivity with relative fluorescence intensity of CD86 ≥ 150% and/or CD54 ≥ 200% at any tested concentrations. Mixtures of PHMG or TCS with PG at ratios of 9:1, 4:1, or 1:4 weight/volume were all positive in terms of SS potential. Since humans can be occupationally or environmentally exposed to mixtures of excipients with active ingredients of biocides, the present study may give insights into further investigations of the SS potentials of various chemical mixtures.

- Abstract
Selective inhibition (SI) has been routinely used to differentiate the contributions of bacteria and fungi to soil ecological processes. SI experiments typically measured rapid responses within hours since the addition of inhibitor, but the long-term effects of selective biocides on microbial community composition and function were largely unknown. In this study, a microcosm experiment was performed with an agricultural soil to explore the effectiveness of two bactericides (bronopol, streptomycin) and two fungicides (cycloheximide, captan), which were applied at two different concentrations (2 and 10 mg g
-1 ). The microcosms were incubated for 6 weeks. A radiolabeled substrate, [1,2,3,4,4a,9a-14 C] anthracene, was spiked to all microcosms, and the derived CO2 was monitored during the incubation. The abundance and composition of bacteria and fungi were assessed by qPCR and Miseq sequencing of ribosomal rRNA genes. It was demonstrated that only 2 mg g-1 bronopol and cycloheximide significantly changed the bacteria to fungi ratio without apparent non-target inhibition on the abundances; however, community shifts were observed in all treatments after 6 weeks incubation. The enrichment of specific taxa implicated a selection of resistant or adapted microbes by these biocides. Mineralization of anthracene was continuingly suppressed in all SI microcosms, which may result in biased estimate of bacterial and fungal contributions to pollutant degradation. These findings highlight the risks of long-term application of selective inhibition, and a preliminary assessment of biocide selection and concentration is highly recommended.- Published

- Abstract
The guanidine family of antimicrobial agents, which includes polyhexamethylene guanidine phosphate (PHMG) and oligo(2-(2-ethoxy)ethoxyethyl) guanidinium chloride (PGH), and chlorophenol biocidal chemicals such as 2,4,4'-trichloro-2'-hydroxydiphenyl ether (triclosan) are used in various occupational and environmental biocidal applications. The excipient propylene glycol (PG) is used to dissolve the active ingredients. The skin sensitization (SS) potential of these substances has not been systemically investigated and is still debated. Moreover, mixtures of PHMG, PGH, or triclosan with PG have not been evaluated for SS potency. An in vivo assay known as the local lymph node assay: 5-bromo-2-deoxyuridine-flow cytometry method (LLNA: BrdU-FCM) was recently adopted as an alternative testing method and was used to address these issues. Via the LLNA: BrdU-FCM, PHMG, PGH, and triclosan were predicted to be sensitizers, while PG was predicted to be a nonsensitizer. In addition, d -limonene, which is used as a flavoring in various consumer products, was also predicted to be a sensitizer, although no unanimous conclusion has been reached regarding its SS potential. Mixtures of PHMG, PGH, triclosan, or d -limonene with PG at ratios of 9:1, 4:1, and 1:4 (w/w) were all positive in terms of SS potential, indicating that the PG excipient does not influence the SS predictions of these chemicals. Since humans can be occupationally and environmentally exposed to mixtures of excipients with active ingredients, the present study may give insight into further investigations of the SS potentials of various chemical mixtures.

- Abstract
Background: This is an updated version of the Cochrane Review previously published in 2017.Epilepsy is a chronic and disabling neurological disorder, affecting approximately 1% of the population. Up to 30% of people with epilepsy have seizures that are resistant to currently available antiepileptic drugs and require treatment with multiple antiepileptic drugs in combination. Felbamate is a second-generation antiepileptic drug that can be used as add-on therapy to standard antiepileptic drugs., Objectives: To evaluate the efficacy and tolerability of felbamate versus placebo when used as an add-on treatment for people with drug-resistant focal-onset epilepsy., Search Methods: For the latest update we searched the Cochrane Register of Studies (CRS Web), MEDLINE, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP), on 18 December 2018. There were no language or time restrictions. We reviewed the reference lists of retrieved studies to search for additional reports of relevant studies. We also contacted the manufacturers of felbamate and experts in the field for information about any unpublished or ongoing studies., Selection Criteria: We searched for randomised placebo-controlled add-on studies of people of any age with drug-resistant focal seizures. The studies could be double-blind, single-blind or unblinded and could be of parallel-group or cross-over design., Data Collection and Analysis: Two review authors independently selected studies for inclusion and extracted information. In the case of disagreements, the third review author arbitrated. Review authors assessed the following outcomes: 50% or greater reduction in seizure frequency; absolute or percentage reduction in seizure frequency; treatment withdrawal; adverse effects; quality of life., Main Results: We included four randomised controlled trials, representing a total of 236 participants, in the review. Two trials had parallel-group design, the third had a two-period cross-over design, and the fourth had a three-period cross-over design. We judged all four studies to be at an unclear risk of bias overall. Bias arose from the incomplete reporting of methodological details, the incomplete and selective reporting of outcome data, and from participants having unstable drug regimens during experimental treatment in one trial. Due to significant methodological heterogeneity, clinical heterogeneity and differences in outcome measures, it was not possible to perform a meta-analysis of the extracted data.Only one study reported the outcome, 50% or greater reduction in seizure frequency, whilst three studies reported percentage reduction in seizure frequency compared to placebo. One study claimed an average seizure reduction of 35.8% with add-on felbamate while another study claimed a more modest reduction of 4.2%. Both studies reported that seizure frequency increased with add-on placebo and that there was a significant difference in seizure reduction between felbamate and placebo (P = 0.0005 and P = 0.018, respectively). The third study reported a 14% reduction in seizure frequency with add-on felbamate but stated that the difference between treatments was not significant. There were conflicting results regarding treatment withdrawal. One study reported a higher treatment withdrawal for placebo-randomised participants, whereas the other three studies reported higher treatment withdrawal rates for felbamate-randomised participants. Notably, the treatment withdrawal rates for felbamate treatment groups across all four studies remained reasonably low (less than 10%), suggesting that felbamate may be well tolerated. Felbamate-randomised participants most commonly withdrew from treatment due to adverse effects. The adverse effects consistently reported by all four studies were: headache, dizziness and nausea. All three adverse effects were reported by 23% to 40% of felbamate-treated participants versus 3% to 15% of placebo-treated participants.We assessed the evidence for all outcomes using GRADE and found it as being very-low certainty, meaning that we have little confidence in the findings reported. We mainly downgraded evidence for imprecision due to the narrative synthesis conducted and the low number of events. We stress that the true effect of felbamate could likely be significantly different from that reported in this current review update., Authors' Conclusions: In view of the methodological deficiencies, the limited number of included studies and the differences in outcome measures, we have found no reliable evidence to support the use of felbamate as an add-on therapy in people with drug-resistant focal-onset epilepsy. A large-scale, randomised controlled trial conducted over a longer period of time is required to inform clinical practice.

- Abstract
Cough is a protective reflex that serves to clear the airways of excessive secretions and foreign matter and which sometimes becomes excessive, and troublesome to patients. Cough is one of the most common reasons why individuals seek medical attention. A range of drugs have been developed in the past with antitussive activity and different mechanisms of action, but there are still very few safe and effective treatments available. The poor tolerability of most available antitussives is closely related to their action on the central nervous system (CNS). An international group of experts specialized in cough met to discuss the need to identify an effective antitussive treatment with a good tolerability profile. The aim of this expert review is to increase the knowledge about the cough mechanism and the activity of levodropropizine, a peripherally acting antitussive drug., (Copyright © 2019 Elsevier Ltd.

- Abstract
Electronic cigarette has the potential to serve as a tobacco cessation aid if the prerequisites which are safety and efficacy in term of nicotine delivery are achieved. The nicotine-based liquids are mainly composed by propylene glycol and glycerol playing the important role of airborne carriers. 1,3 propanediol is proposed as a propylene glycol substitute to potentially improve the thermal stability, nicotine delivery and to decrease inhaled flavors concentrations. We have implemented various thermal, physicochemical and computational methods to evaluate the use of 1,3 propanediol as a substitute (or additional ingredient) to propylene glycol in e-liquids compositions. Our results indicate that 1,3 propanediol is stable upon heating when electronic cigarette are used in recommended conditions. We demonstrate that 1,3 propanediol gave better thermic profile compared to propylene glycol and glycerol, showing less thermal decomposition by-products. In addition, 1,3 propanediol gives to nicotine a more basic environment ensuring a high level of free base nicotine form. We have also established a quantum mechanical based computational method to validate e-liquids as flavor enhancer. Our findings showed that globally 1,3 propanediol seems to have better flavoring properties than glycerol and propylene glycol. Finally, 1,3 propanediol seems to induce quite similar aerodynamic properties compared to propylene glycol and glycerol.

- Abstract
A young female vaper presented with insidious onset cough, progressive dyspnoea on exertion, fever, night sweats and was in respiratory failure when admitted to hospital. Clinical examination was unremarkable. Haematological tests revealed only thrombocytopenia, which was long standing, and her biochemical and inflammatory markers were normal. Chest radiograph and high-resolution CT showed diffuse ground-glass infiltrates with reticulation. She was initially treated with empirical steroids and there was improvement in her oxygenation, which facilitated further tests. Since the bronchoscopy and high-volume lavage was unyielding, a video-assisted thoracoscopicsurgical biopsy was done later and was suggestive of lipoid pneumonia. The only source of lipid was the vegetable glycerine found in e-cigarette (EC). Despite our advice to quit vaping, she continued to use EC with different flavours and there is not much improvement in her clinical and spirometric parameters., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2018.

- Abstract
Cryopreservation has been widely employed to preserve genetic material of aquatic animals. Although of common use in bivalves, resulting effects due to the toxicity of the cryoprotectants dimethyl sulfoxide (DMSO), propanediol (PG), methanol (MET) and ethylene glycol (EG), upon sperm motility in the Chinese pearl oyster, Pinctada fucata martensii, has remained undocumented. This study endeavors to identify the least toxic among the effective cryoprotectant agents by observing and comparing their toxic effects on sperm motility under varying concentrations and duration of exposure. Sperm samples were exposed during controlled experiments, for 1, 3, 6, 9, 12 and 15 min durations, to each of the listed cryoprotectants at 5, 10, 15, and 20% (volume:volume) concentrations. Sperm motility was observed to diminish when exposed to all cryoprotectant solutions, and observations demonstrated that toxicity increased relative to both concentration and equilibration time. After 6 min of exposure to the cryoprotectants, sperm motility was seen to have diminished significantly in DMSO at just 5% concentration, and in MET, PG and EG at 10% concentrations, respectively (the values of the lowest observed effect concentrations). The relationship between the quantity of immotile sperm and the cryoprotectant concentration was described using the logarithmic regression equation. MET exhibited the lowest effective concentration required to inhibit sperm motility by 50% (EC
50 ), followed by EG, PG and DMSO, in order. Therefore, MET proved most toxic under the test conditions for sperm of P. fucata martensii, whereas DMSO, PG and EG were observed as comparatively safer, suggesting that DMSO, PG and EG warrant further study in the application of cryopreservation of Chinese P. fucata martensii sperm., (Copyright © 2018 Elsevier Inc.

- Abstract
The Cosmetic Ingredient Review (CIR) Expert Panel (Panel) reviewed the safety of tromethamine, aminomethyl propanediol, and aminoethyl propanediolas used in cosmetics. All 3 ingredients are reported to function in cosmetics as pH adjusters, and tromethamine and aminomethyl propanediol are also reported to function as fragrance ingredients. The Panel reviewed relevant animal and human data related to these ingredients, along with a previous safety assessment of aminomethyl propanediol. The Panel concluded that tromethamine, aminomethyl propanediol, and aminoethyl propanediol are safe in cosmetics in the practices of use and concentration as given in this safety assessment.

- Abstract
Lineal (poloxamers or Pluronic
® ) or X-shaped (poloxamines or Tetronic® ) amphiphilic tri-block copolymers of poly(ethylene oxide) and poly(propylene oxide) (PEO-PPO-PEO) have been broadly explored for controlled drug delivery in different regenerative medicine approaches. The ability of these copolymers to self-assemble as micelles and to undergo sol-to-gel transitions upon heating has endowed the denomination of "smart" or "intelligent" systems. The use of PEO-PPO-PEO copolymers as gene delivery systems is a powerful emerging strategy to improve the performance of classical gene transfer vectors. This review summarizes the state of art of the application of PEO-PPO-PEO copolymers in both nonviral and viral gene transfer approaches and their potential as gene delivery systems in different regenerative medicine approaches., Competing Interests: The authors declare no conflict of interest.- Published

Jeffamines
® are a family of polymers containing primary amine groups attached to the extremities of polyether backbone which can be used as biomaterials. They have been used in combination with polyethylenimine (PEI) to improve biocompatibility in drug and gene delivery systems. Despite these facts, very few studies have been done on cytotoxicity and genotoxicity of pure Jeffamines® or compared with PEI. The present study aimed to evaluate and compare the cytotoxic and genotoxic effects of Jeffamines® and PEI in CHO-K1 cells. Specifically, polypropylene oxide 2000 (PPO 2000, Jeffamine® D series), polyethylene oxide 1900 (PEO 1900, Jeffamine® ED series), branched 25 kDa PEI, and linear 20 kDa PEI were evaluated at different concentrations. Cell viability and proliferation were assessed by 2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) and 5-bromo-2'-deoxyuridine (BrdU) assays, respectively. Genotoxicity was evaluated using single cell gel electrophoresis assay and the cytokinesis-blocked micronucleus assay. PPO 2000 was the most cytotoxic Jeffamine® , whereas PEO 1900 did not caused significant cell death at any tested concentration. Branched PEI was more cytotoxic than linear PEI (LPEI) and both were more cytotoxic than Jeffamines® . Only PPO 2000 induced DNA damage when evaluated in comet assay probably due to its cytotoxicity. PPO 2000, PEO 1900, and PEI did not increase the frequency of micronuclei when tested at sub-cytotoxic concentrations. This work provides new insights about biocompatibility of Jeffamines® and PEI and suggests the genotoxicological safety for further investigations of PEO 1900 in drug and gene delivery systems. © 2017 Wiley Periodicals, Inc.

- Abstract
70-year-old white man presented with a 6-week history of an acute pruritic eruption in the axillary vaults, inguinal folds, and central lumbar area. Due to the severity of the pruritus, the patient was evaluated in the emergency department. He was treated with intramuscular triamcinolone, oral fluconazole, clobetasol cream, and miconazole powder, which provided only minimal relief. The patient had presented with brightly erythematous patches in the axillary vaults and inguinal folds with numerous erythematous, scaly, coalescing papules and plaques agminated on the lumbar region (Figure). Due to persistence, despite topical corticosteroids, an allergic contact dermatitis was suspected so patch-testing using the T.R.U.E. Test (SMARTPractice Denmark ApS, Hillerod, Denmark) epicutaneous system was conducted. Results were positive for 5-chloro-2-methyl-4-isothazolinone (panel 2.1, #17), budesonide (panel 3.1, #30), and 2-bromo-2-nitropropane-1,3-diol, also known as bronopol (panel 3.1, #36). The patient's topical medications were adjusted based on these results, and he was advised to avoid any products containing these contactants.

- Abstract
Background: This review is an update of a previously published review in the Cochrane Database of Systematic Reviews (Issue 7, 2014) on 'Felbamate as an add-on therapy for refractory epilepsy'. Epilepsy is a chronic and disabling neurologic disorder, affecting approximately 1% of the population. Up to 30% of people with epilepsy have seizures that are resistant to currently available drugs. Felbamate is one of the second-generation antiepileptic drugs and we have assessed its effects as an add-on therapy to standard drugs in this review., Objectives: To evaluate the efficacy and tolerability of felbamate versus placebo when used as an add-on treatment for people with refractory partial-onset epilepsy., Search Methods: For the latest update we searched the Cochrane Epilepsy Specialized Register, CENTRAL, MEDLINE, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform, up to 20 October 2016. There were no language and time restrictions. We reviewed the reference lists of retrieved studies to search for additional reports of relevant studies. We also contacted the manufacturers of felbamate and experts in the field for information about any unpublished or ongoing studies., Selection Criteria: Randomised placebo-controlled add-on studies of people of any age with refractory partial-onset seizures. The studies could be double-blind, single-blind or unblinded and could be of parallel or cross-over design., Data Collection and Analysis: Two review authors independently selected studies for inclusion and extracted information. We resolved disagreements by discussion. If disagreements persisted, the third review author arbitrated. We assessed the following outcomes: 50% or greater reduction in seizure frequency; absolute or percentage reduction in seizure frequency; treatment withdrawal; adverse effects; quality of life., Main Results: We included four randomised controlled trials with a total of 236 participants. Two trials were parallel design, the third had a two-period cross-over design, and the fourth had a three-period cross-over design. Two studies were at an unclear risk of bias for random sequence generation and allocation concealment. These two studies did not include any description of their methods for outcome assessment and performance blinding (i.e. participants or doctors). Two studies were at high risk of bias for incomplete outcome data. Due to significant methodological heterogeneity, clinical heterogeneity and differences in outcome measures, it was not possible to perform a meta-analysis of the results. Only one study reported 50% or greater reduction in seizure frequency. One study reported absolute and percentage reduction in seizure frequency compared to placebo, P values were 0.046 and 0.018, respectively. One study reported percentage reduction in seizure frequency compared to placebo, but there were no P values. Adverse effects rates were higher during the felbamate period than the placebo period, particularly headache, nausea and dizziness., Authors' Conclusions: In view of the methodological deficiencies, limited number of individual studies and differences in outcome measures, we have found no reliable evidence to support the use of felbamate as an add-on therapy in people with refractory partial-onset epilepsy. A large-scale, randomised controlled trial conducted over a longer period of time is required to inform clinical practice.

- Abstract
Introduction: Irritation, such as burning and stinging, on the site of application, is a common side effect of topical dermatologic products including creams, lotions, sprays, and foams. This effect may be more pronounced when applying products to atopic or psoriatic skin. The composition of the vehicle may affect the extent of the irritation. This study compared the irritation and erythema potential of 7 different topical dermatologic products to determine the products with the least likelihood of causing discomfort when applied.
, Methods: Seven sites on the anterior leg of 30 subjects were dry shaven with 10 upward strokes. Subjects rated the stinging of petrolatum (negative control), isopropyl alcohol (positive control), Cetaphil Lotion, triamcinolone 0.1% cream, triamcinolone 0.2% spray, betamethasone foam, and clobetasol 0.05% spray, 1 minute after product application, using a scale of 0 (no symptoms) to 10 (intolerable stinging/burning). The investigator assessed erythema at the sites 30 minutes after application of the products using a scale of 0 (none) to 4 (severe).
, Results: Stinging rating score of each product was statistically significant from one another. Petrolatum produced the least stinging (0) and isopropyl alcohol the most (10). Stinging with triamcinolone spray, Cetaphil Lotion, and triamcinolone cream ranked in the lower half of the rating scale (all below 5). Betamethasone foam and clobetal spray ranked the highest at >7. When corrected for the erythema caused by shaving, triamcinolone spray and Cetaphil Lotion produced the least amount of erythema of all the products tested.
, Discussion: Rapid evaporation of the volatile vehicle of triamcinolone spray and the non-irriating nature of the medication left behind may contribute to its low erythema and stinging. This product may be an appropriate choice for patients with compromised skin but who require the advantages and conveniences of a spray vehicle. , , J Drugs Dermatol. 2016;15(7):870-873.- Published

- Abstract
Introduction: Felbamate was approved in 1993 to treat partial seizures with and without secondary generalization in adults and in Lennox-Gastaut Syndrome in children. Its use was later restricted when rare but fatal cases of aplastic anemia and hepatic failure were identified., Methods: This single center analysis retrospectively evaluated the safety and efficacy of felbamate in a cohort of children, adolescents, and adults with epilepsy., Results: A chart review identified 103 patients taking felbamate. The range of felbamate dose was 300-4500 mg (mean: 1800 ± 900 mg). The duration of therapy ranged from 1 month to 20 years (mean duration: 35 ± 45 months). Eighteen (17.5%) subjects experienced adverse events including insomnia, nausea, vomiting, decreased appetite, weight loss, gastric discomfort, diarrhea, mood and behavioral problems, high blood pressure, headache, and elevated liver enzymes. Out of these, 6 (5.9%) patients discontinued the therapy. No hepatic failure or agranulocytosis was observed. Fifty-nine (57.72%) patients achieved ≥ 50% reduction in seizure frequency, and 30 (29.12%) patients achieved seizure freedom., Conclusions: These findings suggest that felbamate is safe, well tolerated, and effective in treatment of various types of epilepsy syndromes., (Copyright © 2016 Elsevier Inc.

- Abstract
Since most liposuction incisions heal uneventfully, difficult healing in such incisions must be investigated. In the cases of two gynecomastia liposuction patients in which a water-based lubricating gel was used on the liposuction incisions, the incisions failed to heal. For both patients, workup uncovered palisading granulomas at the lateral inframammary fold incision sites several months after otherwise successful surgeries. These two cases are presented and the previous literature is reviewed, with consideration given to the etiology and prevention of such granulomas.

- Abstract
Background: Oral fingolimod is a sphingosine-1-phosphate-receptor modulator that prevents the egress of lymphocytes from lymph nodes. Fingolimod reduces relapse rate and delays disability progression in patients with relapsing forms of multiple sclerosis (MS). Elevation of liver function tests (LFTs) and reduction in peripheral-blood lymphocyte counts were among the most common adverse events reported in phase II, phase III, and extension studies., Objective: To describe eight patients in whom fingolimod dose was reduced to every other day (n=6) or every third day (n=2) due to increased LFTs more than 3 times the upper limit of normal (ULN) (n=2) or decreased lymphocyte count by ≤0.2×10(9)/L (n=6)., Results: Fingolimod dose reduction resulted in reversal of laboratory abnormalities. Clinically, none of the 8 patients developed clinical relapses, but five patients had new lesions on magnetic resonance imaging (MRI), one of whom with disability progression, and one patient converted to secondary progressive MS (SPMS)., Conclusion: Reducing the frequency of fingolimod administration can reverse laboratory abnormalities but may have a negative impact on drug efficacy., (Copyright © 2015 Elsevier B.V.

- Abstract
A 51-year-old woman with relapsing-remitting multiple sclerosis was initiated on fingolimod. She developed a Mobitz Type I (Wenckebach)second-degree atrioventricular (AV) heart block during the initial 6-hour monitoring. She was transferred to the emergency department for further monitoring, where she went into a junctional tachycardia then went back into a Mobitz Type I AV block. The patient was symptomatic with a heart rate nadir of 38 beats per minute and treated with atropine. Junctional tachycardia has not been previously reported with fingolimod use. Patients may require extended cardiac monitoring after fingolimod administration.

- Abstract
Objective: To assess long-term safety and efficacy of fingolimod in patients with relapsing-remitting multiple sclerosis (RRMS)., Methods: Patients completing FTY720 Research Evaluating Effects of Daily Oral Therapy in MS (FREEDOMS) were eligible for this dose-blinded, parallel-group extension study, continuing fingolimod 0.5 mg/day or 1.25 mg/day, or switching from placebo to either dose, randomized 1:1. Efficacy variables included annualized relapse rate (ARR), brain volume loss (BVL), and confirmed disability progression (CDP). Between-group analyses were conducted in the intent-to-treat (ITT) population from FREEDOMS baseline to end of study. Within-group analyses compared years 0-2 (FREEDOMS) and years 2-4 (extension) in the extension ITT population., Results: Of 1,272 patients (FREEDOMS ITT population), 1,033 were eligible, and 920 enrolled in the extension study (continuous-fingolimod: 0.5 mg [n = 331], 1.25 mg [n = 289]; placebo-fingolimod: 0.5 mg [n = 155], 1.25 mg [n = 145]); 916 formed the extension ITT population (n = 330; n = 287; n = 154; n = 145) and 773 (84%) completed. In the continuous-fingolimod groups, ARR was lower (p < 0.0001), BVL was reduced (p < 0.05), and proportionately more patients were free from 3-month CDP (p < 0.05) than in a group comprising all placebo-fingolimod patients. Within each placebo-fingolimod group, ARR was lower (p < 0.001, both) and BVL was reduced after switching (p < 0.01, placebo-fingolimod 0.5 mg). Rates and types of adverse events were similar across groups; no new safety issues were reported., Conclusion: Efficacy benefits of fingolimod during FREEDOMS were sustained during the extension; ARR and BVL were reduced after switching., Classification of Evidence: This study provides Class IV evidence that long-term fingolimod treatment is well-tolerated and reduces relapse rates, disability progression, and MRI effects in patients with RRMS., (© 2015 American Academy of Neurology.)

- Abstract
Purpose: The efficacy and safety of the three oral agents approved by the Food and Drug Administration for the treatment of relapsing-remitting multiple sclerosis (RRMS) are reviewed., Summary: Limitations to parenteral disease-modifying therapies (DMTs) (interferon beta-1a, interferon beta-1b, and glatiramer acetate) for the treatment of RRMS have been addressed by the approval of three oral DMTs: fingolimod, teriflunomide, and dimethyl fumarate. In clinical trials, each of the oral DMTs was superior to placebo in annualized relapse rate, a key indicator of clinical efficacy, and in neuroradiological efficacy. A reduction in disability progression was evident with higher doses of teriflunomide but was not consistently demonstrated with fingolimod or dimethyl fumarate. Each of the oral DMTs demonstrated acceptable safety in clinical trials, with adverse-effect profiles that differ from injectable agents. The safety of both teriflunomide and dimethyl fumarate is supported by long-term use of related agents for other diseases; however, postmarketing surveillance studies are needed to determine the safety of each of the oral DMTs in patients with RRMS. Dimethyl fumarate seems to have the most innocuous safety profile of the three agents. Fingolimod requires first-dose inpatient monitoring due to cardiac safety concerns and multiple laboratory tests prior to initiation of therapy, while teriflunomide has been associated with hepatotoxicity and teratogenicity., Conclusion: With the approval of three oral drugs for RRMS-fingolimod, teriflunomide, and dimethyl fumarate-the therapeutic strategy for RRMS has evolved to include options that are efficacious and appear to have administration advantages over established parenteral treatments., (Copyright © 2015 by the American Society of Health-System Pharmacists, Inc.

- Abstract
Background: Patch testing is an important diagnostic tool for assessment of allergic contact dermatitis (ACD)., Objective: This study documents the North American Contact Dermatitis Group (NACDG) patch-testing results from January 1, 2011, to December 31, 2012., Methods: At 12 centers in North America, patients were tested in a standardized manner with a series of 70 allergens. Data were manually verified and entered into a central database. Descriptive frequencies were calculated, and trends analyzed using χ statistics., Results: Four thousand two hundred thirty-eight patients were tested; of these, 2705 patients (63.8%) had at least 1 positive reaction, and 2029 (48.0%) were ultimately determined to have a primary diagnosis of ACD. Four hundred eight patients (9.6%) had occupationally related skin disease. There were 7532 positive allergic reactions. As compared with previous reporting periods (2009-2010 and 2000-2010), positive reaction rates statistically increased for 6 allergens: methylchloroisothiazolinone/methylisothiazolinone (5.0%; risk ratios [RRs]: 2.01 [1.60-2.52], 1.87 [1.61-2.18]), lanolin alcohol (4.6%; RRs 1.83 [1.45-2.30], 2.10 [1.79-2.47]), cinnamic aldehyde (3.9%; 1.69 [1.32-2.15], 1.53 [1.28-1.82]), glutaral (1.5%; 1.67 [1.13-2.48], 1.31 [1.00-1.71]), paraben mix (1.4%; 1.77 [1.16-2.69], 1.44 [1.09-1.92]), and fragrance mix I (12.1%; RRs 1.42 [1.25-1.61], 1.24 [1.14-1.36]). Compared with the previous decade, positivity rates for all formaldehyde-releasing preservatives significantly decreased (formaldehyde 6.6%; RR, 0.82 [0.73, 0.93]; quaternium-15 6.4% RR 0.75 [0.66, 0.85]; diazolidinyl urea 2.1%; RR, 0.67 [0.54, 0.84]; imidazolidinyl urea 1.6%, 0.60 [0.47, 0.77]; bronopol 1.6%; RR, 0.60 [0.46, 0.77]; DMDM hydantoin 1.6%; RR, 0.59 [0.54, 0.84]). Approximately a quarter of patients had at least 1 relevant allergic reaction to a non-NACDG allergen. In addition, approximately one-fourth to one-third of reactions detected by NACDG allergens would have been hypothetically missed by T.R.U.E. TEST (SmartPractice Denmark, Hillerød, Denmark)., Conclusions: These data document the beginning of the epidemic of sensitivity to methylisothiazolinones in North America, which has been well documented in Europe. Patch testing with allergens beyond a standard screening tray is necessary for complete evaluation of occupational and nonoccupational ACD.

- Abstract
Felbamate has been approved for refractory partial seizures since the early nineties. Due to safety concerns regarding its use, namely, in aplastic anemia and hepatic failure, felbamate's use has been restricted and a 'Black Box' warning has been inserted. Nonetheless, it is a useful drug in refractory cases of partial epilepsy. There are certain precautions which can prevent and minimize the serious idiosyncratic reactions associated with felbamate, thereby providing an option in refractory cases where no other drug works.

- Abstract
Peripheral lymphocytes entering brain ischemic regions orchestrate inflammatory responses, catalyze tissue death, and worsen clinical outcomes of acute ischemic stroke (AIS) in preclinical studies. However, it is not known whether modulating brain inflammation can impact the outcome of patients with AIS. In this open-label, evaluator-blinded, parallel-group clinical pilot trial, we recruited 22 patients matched for clinical and MRI characteristics, with anterior cerebral circulation occlusion and onset of stroke that had exceeded 4.5 h, who then received standard management alone (controls) or standard management plus fingolimod (FTY720, Gilenya, Novartis), 0.5 mg per day orally for 3 consecutive days. Compared with the 11 control patients, the 11 fingolimod recipients had lower circulating lymphocyte counts, milder neurological deficits, and better recovery of neurological functions. This difference was most profound in the first week when reduction of National Institutes of Health Stroke Scale was 4 vs. -1, respectively (P = 0.0001). Neurological rehabilitation was faster in the fingolimod-treated group. Enlargement of lesion size was more restrained between baseline and day 7 than in controls (9 vs. 27 mL, P = 0.0494). Furthermore, rT1%, an indicator of microvascular permeability, was lower in the fingolimod-treated group at 7 d (20.5 vs. 11.0; P = 0.005). No drug-related serious events occurred. We conclude that in patients with acute and anterior cerebral circulation occlusion stroke, oral fingolimod within 72 h of disease onset was safe, limited secondary tissue injury from baseline to 7 d, decreased microvascular permeability, attenuated neurological deficits, and promoted recovery.

- Abstract
Objective: To assess whether pretreatment-lymphocyte counts, treatment before fingolimod, age, sex, or body mass index (BMI) affects the risk of fingolimod-induced lymphopenia in patients with relapsing-remitting multiple sclerosis (RRMS)., Methods: Data were obtained from a German multicenter, single-arm, open-label study of patients with RRMS treated with fingolimod, and findings were validated in an independent Swedish national pharmacovigilance study., Results: Four hundred eighteen patients with RRMS from Germany and 438 patients from Sweden were included. A nadir ≤0.2 × 10(9) lymphocytes/L was reached in 15% (95% confidence interval [CI] 12%-17%) of all 856 patients. Patients with lower starting lymphocyte counts (below 1.6 × 10(9)/L) and patients with BMI lower than 18.5 kg/m(2) (women only) were at higher risk of developing lymphopenia with values ≤0.2 × 10(9)/L in the combined analysis, increasing the risk in these subgroups to 26% (95% CI 20%-31%) or 46% (95% CI 23%-71%), respectively. In the German cohort, infection rates were similar in patients who developed severe lymphopenia and those who did not., Conclusions: Our findings suggest that patients with low baseline lymphocyte counts and underweight women in which fingolimod treatment will be initiated should possibly be monitored more closely., (© 2014 American Academy of Neurology.)

- Abstract
Aim: Fingolimod, a sphingosine 1-phosphate receptor modulator, is the first oral disease modifying therapy approved for the treatment of relapsing multiple sclerosis. The aim of this double-blind, placebo-controlled study was to evaluate the effect of fingolimod on cerebral blood flow, platelet function and macular thickness in healthy volunteers., Methods: The study included 88 healthy volunteers who received fingolimod 0.5 mg or 1.25 mg or matched placebo over a period of 4 weeks. Transcranial colour coded sonography was performed to measure mean blood flow velocities, the platelet function was measured by the PFA-100® assay using a collagen/epinephrine cartridge and macular thickness was measured using optical coherence tomography. An assessment of non-inferiority of fingolimod vs. placebo was performed against a reference value (20% of the overall baseline value)., Results: All 88 randomized participants completed the study. At day 28 compared with baseline value, for 0.5 mg, 1.25 mg and placebo treatments, the mean middle cerebral artery blood flow velocity decreased by 4, 1 and 3.7 cm s(-1), respectively. The platelet function analyzer closure time increase was not significant (7.8, 7.5 and 10.4 s, respectively). The mean percentage change in the central foveal thickness from baseline for both eyes was below 3% for all groups. The safety profile of fingolimod in this study was found consistent with the previous reports., Conclusions: In healthy volunteers, the changes seen with both fingolimod doses were found to be within normal variability, non-inferior and comparable with those observed with placebo for all the pharmacodynamic parameters assessed., (© 2014 The British Pharmacological Society.)

- Abstract
The three dimensional (3D) cell culture in polymer-based micro system has become a useful tool for in vitro drug discovery. Among those polymers, polysulfone hollow fiber membrane (PSf HFM) is commonly used to create a microenvironment for cells. However, the target drug may adsorb on the polymeric surface, and this elicits negative impacts on cell exposure due to the reduced effective drug concentration in culture medium. In order to reduce the drug adsorption, PSf membrane were modified with hydrophilic Pluronic (PEO-b-PPO-b-PEO) copolymers, L121, P123 and F127 (PEO contents increase from 10%, 30% to 70%), by physical adsorption. As a result, the hydrophilicity of HFMs increased at an order of PSf
F127>P123>L121 HFMs. The three modified membrane all showed significant resistance to adsorption of acid/neutral drugs. More importantly, the adsorption of base drugs were largely reduced to an average value of 11% on the L121 HFM. The improved resistance to drug adsorption could be attributed to the synergy of hydrophobic/neutrally charged PPO and hydrophilic PEO. The L121 HFM was further assessed by evaluating the drug hepatotoxicity in 3D culture of hepatocytes. The base drugs, clozapine and doxorubicin, showed more sensitive hepatotoxicity on hepatocytes in L121 HFM than in PSf HFM, while the acid drug, salicylic acid, showed the similar hepatotoxicity to hepatocytes in both HFMs. Our finding suggests that PSf HFM modified by PEO-b-PPO-b-PEO copolymers can efficiently resist the drug adsorption onto polymer membrane, and consequently improve the accuracy and sensitivity of in vitro hepatotoxic drug screening., (Copyright © 2014 Elsevier B.V.

- Abstract
Multiple sclerosis (MS), an inflammatory disorder of the central nervous system, is characterized by relapsing-remitting (RR) clinical course. Fingolimod was the first oral therapy to prevent relapses in patients with RRMS, approved in Japan in 2011. In lymph node, fingolimod acts as functional antagonist, leading to internalization of sphingosine-1-phosphate 1(S1P1) receptors of lymphocytes. Lymphocytes in lymph nodes bearing S1P1 receptors cannot egress from lymph nodes. As a result, lymphocyte count in the circulation is reduced. Fingolimod showed reduced relapses, and suppressed the number of enhancing lesion and the progression of brain atrophy of brain MRI, however, it also showed some adverse effects such as bradycardia, herpes zoster infection, macular edema, liver dysfunction, and teratogenic properties. We proposed indications of fingolimod therapy, and reduced dosage therapy of fingolimod for patients with a lymphocyte count below 0.2 x 10(9) cells/L.

- Abstract
Dual polarization interferometry was used to monitor the immobilization dynamics of four Pluronics on hydrophobic surfaces and to elucidate the effect of Pluronic conformation on protein adsorption. The proportion of hydrophobic chain segments and not the length of the hydrophobic chain can influence the chain densities of the Pluronics. The immobilized densities of the Pluronics resulted from competition between the hydration of polyethylene oxide (PEO) in the aqueous solution and the hydrophobic interaction of polypropylene oxide on the substrate. P-123 obtained the largest graft mass (2.89±0.25 ng/mm2) because of the dominant effect of hydrophobic interactions. Hydrophobic segments of P-123 were anchored slowly and step-wise on the C18 substrate. P-123 exhibited the largest hydrophobic chain segment proportion (propylene oxide/ethylene oxide=3.63) and formed a brush chain conformation, indicating excellent protein and platelet resistance. The result of quartz crystal microbalance with dissipation further confirmed that the PEO conformation in P-123 on the substrate exhibited a relatively extended brush chain, and that L-35 showed relatively loose and pancake-like structures. The PEO in P-123 regulated the conformation to maintain the native conformation and resist the adsorption of bovine serum albumin (BSA). Thus, the hemocompatibilities of the immobilized Pluronics were influenced by the proportion of hydrophobic chain segments and their PEO conformations., (Crown Copyright © 2014.

- Abstract
Although few recent studies have reported efficacy and safety data among patients with multiple sclerosis (MS) switching between immunotherapies, data on the mechanism of rebound activity postwithdrawal of fingolimod in patients with MS is scarce. A 36-year-old woman developed severe reactivation of her disease within 7 weeks of fingolimod's withdrawal despite the absence of breakthrough disease during the 8-week natalizumab washout period previously. The clinical presentation and radiological features were described indicating the diagnostic challenge given the potential risk of developing progressive multifocal leucoencephalopathy. The severe reactivation postwithdrawal of fingolimod could be due to the immune reconstitution inflammatory syndrome (IRIS) given the abrupt rise in lymphocyte count. Patients who discontinued fingolimod might be at risk of developing IRIS resulting in disease reactivation in the washout period., (2014 BMJ Publishing Group Ltd.)

- Abstract
Three FDA-approved oral medications are available for the treatment of relapsing forms of multiple sclerosis: fingolimod, teriflunomide, and dimethyl fumarate. While injection and IV treatments have proven to be beneficial, these newer oral agents also offer positive outcomes for patients. Numerous barriers exist, though, for these oral agents, including the unknown long-term efficacy and safety and potential side effects. Despite possible side effects, oral agents provide convenience, ease of use, and the elimination of injection/IV administration-site pain. To ensure MS patients receive the most appropriate individualized care, clinicians should present all of the available treatment options to both newly diagnosed and established patients., (© Copyright 2014 Physicians Postgraduate Press, Inc.)

- Abstract
Amenorrhea has not been reported as an adverse event in fingolimod phase III clinical trials in patients with multiple sclerosis (MS) with either 0.5 mg or 1.25 mg dosages. Here we report three cases of young women with MS who developed amenorrhea within 6 months of initiation of fingolimod. They experienced irregularities in their menstrual cycles in the first 3 months, which progressed to amenorrhea by 5(th) or 6(th) month. Gynecology evaluations showed no other etiologies. Menses returned to baseline after discontinuation of fingolimod for 2-3 months. Amenorrhea could be associated with fingolimod in the first year. Future surveillance is advised to determine the incidence rate of this adverse event., (© The Author(s) 2014.)

- Abstract
Finglimod, a sphingosine 1-phosphate receptor modulator, is the first orally administered therapy approved for prophylaxis in multiple sclerosis (MS). Several reports in the last two years suggested that it might be associated with severe augmentation of disease activity upon initiation or discontinuation of therapy. We present an MS patient who developed a giant cavitating brain lesion under fingolimod and in whom cessation of therapy was associated with a very active course. Brain biopsy revealed the lesion to be due to an active demyelinating inflammatory process. With the current wave of immunosuppressive treatments for MS, there is a need to be vigilant to side effects and risks not identified in large multicenter trials, collect the data and set guidelines and precautions for present and future medications., (Copyright © 2014 Elsevier B.V.

- Abstract
Background: Fingolimod is an oral sphingosine-1-phosphate-receptor modulator, which has demonstrated efficacy in clinical trials and has recently been approved for multiple sclerosis (MS) treatment in Kuwait. Post-marketing studies are important to demonstrate real-life efficacy and safety., Objective: The objective of this study was to examine the efficacy and safety of fingolimod treatment in a clinical setting., Methods: Using the national Kuwait MS registry, relapsing remitting MS patients who had been prescribed fingolimod for ≥6 months were retrospectively identified. Three-monthly clinical evaluations and 6-monthly magnetic resonance imagings (MRIs) were performed. Patient status pre- and post-treatment was compared using chi-square and Student t-tests., Results: A total of 175 patients were included: 75.4 % female (n = 132); mean age 33.3 ± 9.2 years; mean disease duration 7.2 ± 5.2 years; mean fingolimod use 21.7 ± 9.1 months. Most had used previous disease-modifying therapy (78.9 %; n = 138), mainly interferons (66.9 %; n = 117). Twenty-three patients (11.4 %) discontinued/withdrew fingolimod; of whom eight had relapses. The proportion of relapse-free patients improved significantly (86.3 % vs. 32.6 %; p < 0.001), while the proportion of patients with MRI activity decreased (18.3.6 % vs. 77.7 %; p < 0.001). Mean expanded disability status scale (EDSS) score at the last visit improved when compared with pre-treatment (2.26 ± 1.49 vs. 2.60 ± 1.44; p = 0.03). Forty-three (24.6 %) patients experienced adverse events; headaches and lymphopenia were the most commonly reported adverse events., Conclusion: Fingolimod treatment was associated with reduced relapse and MRI activity, and an improved EDSS score. Discontinuation/withdrawal rates and adverse events were low. Fingolimod presents a promising treatment for MS in Kuwait.

- Abstract
Fingolimod is a new and efficient treatment for multiple sclerosis (MS). The drug administration requires special attention to the first dose, since cardiovascular adverse events can be observed during the initial six hours of fingolimod ingestion. The present study consisted of a review of cardiovascular data on 180 patients with MS receiving the first dose of fingolimod. The rate of bradycardia in these patients was higher than that observed in clinical trials with very strict inclusion criteria for patients. There were less than 10% of cases requiring special attention, but no fatal cases. All but one patient continued the treatment after this initial dose. This is the first report on real-life administration of fingolimod to Brazilian patients with MS, and one of the few studies with these characteristics in the world.
