Objectives This network meta-analysis aimed to assess the safety profiles of seven commonly used oral antimuscarinic drugs (darifenacin, fesoterodine, imidafenacin, oxybutynin, propiverine, solifenacin, and tolterodine) in patients with overactive bladder (OAB). Methods PubMed, Cochrane Library, EMBASE, CNKI, and Wanfang databases were searched for randomized controlled trials (RCTs). Studies comparing one or more antimuscarinic drugs for treating OAB with reported adverse effects (AEs) were eligible. Data were extracted, and a network meta-analysis was performed by two authors independently. Results Forty-five RCTs and 124,587 patients were included. The results demonstrated that tolterodine had better safety outcomes for 7 out of 12 major AEs, including dry mouth, constipation, urinary retention, dizziness, urinary tract infection, dry eyes, and dry skin. Darifenacin, fesoterodine, imidafenacin, oxybutynin, and solifenacin presented comparable safety profiles. Conclusions Tolterodine may be preferable as it showed a reduced association with important AEs. Darifenacin, fesoterodine, imidafenacin, oxybutynin, and solifenacin have similar safety profiles in treating patients with OAB. Taken together, this analysis provides a valuable overview of the therapeutic safety for oral antimuscarinic drugs and is useful for personalized medicine in patients with OAB. Trial registration: This trial was retrospectively registered at INPLASY ( https://inplasy.com/ ) with the registration number 202170095.

Overactive bladder syndrome (OAB) is defined by the International Continence Society (ICS) as urinary urgency with increased daytime frequency and nocturia in the absence of proven infection or any other pathology, usually with or without urgency incontinence. Pharmacotherapy with antimuscarinic drugs is highly effective, but more than 60% of patients discontinue the treatment. Development of mirabegron, a β3-adrenoceptor agonist (β3-AR), has become an expected pharmacotherapy option for the non-invasive treatment of overactive bladder. The available studies show that long-term treatment with 50 mg mirabegron in patients with OAB is associated with reducing the severity of symptoms. Data from clinical trials show that mirabegron provides efficacy similar to antimuscarinic drugs, but with a better tolerance profile.

Background: Overactive bladder syndrome is a broadly occurring urological disorder with a distressing impact on the quality of life. The commonly used antimuscarinic drugs show poor patient compliance because of unsatisfactory potency, tolerability and high occurrence of adverse effects such as dry mouth, blurred vision, constipation, dizziness etc. Mirabegron is the first approved β3-adrenoreceptor agonist, used as mono or in combination therapies for overactive bladder syndrome. Objective: The present review provides an insight into the mechanism, pharmacokinetics, toxicokinetics, clinical trials and the development of various conventional and modified-release dosage forms of mirabegron for the treatment of overactive bladder syndrome. Results: The clinical trials of phase II and phase III of mirabegron demonstrated symptomatic relief from the overactive bladder without disturbing the micturition cycle. To date, mirabegron showed promising results for safety, tolerability and efficacy in patients with overactive bladder syndrome. The modified-release tablet dosage form of mirabegron appear to be a proficient and suitable replacement for antimuscarinics and revealed the tremendous potential to overcome the adverse effects of conventional antimuscarinic drugs like Oxybutyline chloride ER, Detrol LA, VESIcare, etc. Conclusion: Mirabegron shows a distinct mode of action, i.e., targeting β3-adrenoreceptors and improving bladder storage without altering void contractions. The limited side effects, high safety, efficacy and tolerability of mirabegron present an adequate substitute to antimuscarinics. However, long-term analysis and clinical studies are prerequisites for assessing the safety, tolerability and efficacy profile of mirabegron.
