Jiang YH, Kuo HC. Current optimal pharmacologic therapies for overactive bladder. Expert Opin Pharmacother 2023; 24:2005-2019. [PMID: 37752121 DOI: 10.1080/14656566.2023.2264183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 09/25/2023] [Indexed: 09/28/2023]
Abstract
INTRODUCTION Overactive bladder (OAB) is a common syndrome in adults. Current pharmacologic treatment includes antimuscarinic agents and β-3 adrenoceptor agonists. For non-responders to oral medication, intravesical injection of botulinum toxin A (BoNT-A) is an effective option. However, these treatments have potential adverse events and should be cautiously selected for appropriate patients. This review presents the recently published results of clinical trials and studies for patients with OAB and the underlying pathophysiology of OAB. Appropriate medical therapy based on pathophysiology of OAB is also presented. AREAS COVERED Literature search from Pubmed from 2001 to 2023 including clinical background, pharmacology, and clinical studies for OAB medications. EXPERT OPINION Treatment of OAB syndrome with any antimuscarinic or β-3 adrenoceptor agonist is feasible as a first-line approach. For patients with suboptimal therapeutic effect to full-dose antimuscarinics or mirabegron, combination with both drugs can improve efficacy. Intravesical BoNT-A 100-U injection provides therapeutic effects for refractory OAB. Patients who are refractory to initial pharmacotherapies should be investigated for the underlying pathophysiology; then an appropriate medication can be added, such as an α1-blocker or anti-inflammatory agents. Patient education about behavioral modification and therapies should always be provided with oral medication or BoNT-A injection for OAB patients.

Akkoc Y. Efficacy and safety of mirabegron for treatment of neurogenic detrusor overactivity in adults with spinal cord injury or multiple sclerosis: a systematic review. Spinal Cord 2022; 60:854-861. [PMID: 36085413 DOI: 10.1038/s41393-022-00853-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Revised: 08/26/2022] [Accepted: 08/29/2022] [Indexed: 12/24/2022]
Abstract
STUDY DESIGN Systematic review. OBJECTIVE To evaluate the efficacy and safety of mirabegron in patients with neurogenic detrusor overactivity due to SCI or MS. METHODS A comprehensive search of the Pubmed, Cochrane, Scopus, and Embase databases was performed. Studies evaluating adult patients with neurogenic detrusor overactivity due to SCI or MS were analyzed according to clinical and urodynamic outcome parameters. RESULTS A total of 488 patients were included in 11 studies, with sample sizes ranging from 15 to 91. The duration of the treatments varied from 4 weeks to 12 months. Mirabegron was used as a secondline treatment after anticholinergics in most of the studies. While clinical outcome parameters are used in studies involving only MS patients, urodynamic outcome parameters are also used in studies involving patients with SCI. The efficacy of mirabegron was found not to be different than anticholinergics when compared in MS patients. Comprehensive urodynamic evaluation was performed in 2 randomized, double-blind, placebo-controlled studies and no satisfactory results were obtained compared to placebo. In retrospective studies there were some significant improvements in Pdet(max), MCC and compliance. The major safety concern with mirabegron is cardiovascular safety. In one study, tachyarrhythmia and palpitations reported in a patient with SCI at C6 level, in another study tachycardia reported in one patient with MS. CONCLUSIONS Although mirabegron demonstrates similar clinical efficacy to anticholinergics in MS patients, its effect on urodynamic parameters in patients with SCI cannot be considered satisfactory. It has a good safety profile with mild cardiovascular side effects.

Kuo HC. How to choose appropriate medication for overactive bladder: Findings from the largest integrated clinical trial database analysis of mirabegron studies. Tzu Chi Med J 2022; 34:23-28. [PMID: 35233352 PMCID: PMC8830553 DOI: 10.4103/tcmj.tcmj_167_20] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 07/08/2020] [Accepted: 07/22/2020] [Indexed: 11/04/2022] Open
Abstract
Medical treatment of overactive bladder (OAB) includes antimuscarinic agents, beta-3 adrenoceptor agonist (mirabegron), or combination with both drugs. Recently, a meta-analysis reported the integrated clinical trial data from 10 phase 2–4, double-blind, 12-week mirabegron monotherapy studies. The results confirmed that mirabegron is as effective as the previously used antimuscarinic agent to treat OAB. The treatment-emergent adverse events were similar across subgroups. This article comments on this largest integrated clinical trial data analysis, and reviews the recently published literature and tries to reveal how to choose the appropriate medication for OAB. For OAB patients, starting from antimuscarinic agent is feasible. However, if the patients have risk of cognitive dysfunction, a history of constipation, dry mouth, and urinary retention, starting with mirabegron 50 mg might be more safe and appropriate. In the elderly patients with low detrusor contractility, with central nervous system lesion, and men with benign prostatic hyperplasia, starting from 25 mg mirabegron is recommended. If the treatment result is not satisfactory to the 25 mg mirabegron, increase dose to 50 mg mirabegron is appropriate. In patients who have failed from the first OAB medication either with antimuscarinics or mirabegron 50 mg, the exchange of the OAB medication to each other should be tried first. If the treatment result is still not satisfactory, a combination of antimuscarinics and mirabegron is recommended.

Abstract
Background and Objective: Over the past few years, mirabegron has been increasingly used as a therapeutic option for neurogenic lower urinary tract dysfunction. Here, we carried out a meta-analysis to investigate the efficacy and safety of mirabegron for the treatment of neurogenic lower urinary tract dysfunction. Methods: We used a range of databases to retrieve randomized controlled trials (RCTs) relating to mirabegron in patients with neurogenic lower urinary tract dysfunction: PubMed, Embase, and Cochrane Library; our strategy conformed to the PICOS (populations, interventions, comparators, outcomes, and study designs) strategy. Results: Our analyses involved four RCTs involving 245 patients. We found that mirabegron treatment resulted in a significant improvement in bladder compliance [mean difference (MD) = 19.53, 95% confidence interval (CI): 14.19 to 24.87, P < 0.00001], urinary incontinence episodes (MD = −0.78, 95% CI: −0.89 to −0.67, P < 0.00001) and Incontinence Quality of Life (I-QOL) (MD = 8.02, 95% CI: 3.20 to 12.84, P = 0.001). Significant differences were detected in terms of Patient Perception of Bladder Condition (PPBC) (MD = −0.54, 95% CI: −1.46 to 0.39, P = 0.26) and urinary urgency episodes (MD = −0.72, 95% CI: −3.1 to 1.66, P = 0.55). With regard to safety, there were no significant differences between mirabegron and control groups in terms of the incidence of drug-related adverse events [odds ratio (OR): 0.83, 95% CI: 0.43 to 1.59, P = 0.57], arrhythmias (OR: 1.27, 95% CI: 0.37 to 4.38, P = 0.70), hypertension (OR: 0.70, 95% CI: 0.13 to 3.82, P = 0.68), or post-voiding residual volume (MD: 1.62, 95% CI: −9.00 to 12.24, P = 0.77). Conclusion: Mirabegron is an efficacious and safe treatment for patients with neurogenic lower urinary tract dysfunction.

Abstract
Progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS; the most common phenotype of corticobasal degeneration) are tauopathies with a relentless course, usually starting in the mid-60s and leading to death after an average of 7 years. There is as yet no specific or disease-modifying treatment. Clinical deficits in PSP are numerous, involve the entire neuraxis, and present as several discrete phenotypes. They center on rigidity, bradykinesia, postural instability, gait freezing, supranuclear ocular motor impairment, dysarthria, dysphagia, incontinence, sleep disorders, frontal cognitive dysfunction, and a variety of behavioral changes. CBS presents with prominent and usually asymmetric dystonia, apraxia, myoclonus, pyramidal signs, and cortical sensory loss. The symptoms and deficits of PSP and CBS are amenable to a variety of treatment strategies but most physicians, including many neurologists, are reluctant to care for patients with these conditions because of unfamiliarity with their multiplicity of interacting symptoms and deficits. CurePSP, the organization devoted to support, research, and education for PSP and CBS, created its CurePSP Centers of Care network in North America in 2017 to improve patient access to clinical expertise and develop collaborations. The directors of the 25 centers have created this consensus document outlining best practices in the management of PSP and CBS. They formed a writing committee for each of 12 sub-topics. A 4-member Steering Committee collated and edited the contributions. The result was returned to the entire cohort of authors for further comments, which were considered for incorporation by the Steering Committee. The authors hope that this publication will serve as a convenient guide for all clinicians caring for patients with PSP and CBS and that it will improve care for patients with these devastating but manageable disorders.

Abstract
Introduction: Bladder and urinary sphincter malfunctioning that results from some change in the central and/or peripheral nervous system is defined as neurogenic bladder. The urinary tract symptoms that can be related to its filling, emptying, or both have a significant impact on the quality of life of individuals. The present review was based on the document prepared for the public health system in Brazil as a treatment guidelines proposal. Material and Methods: Survey questions were structured as per PICO (Population, Intervention, Control, and Outcome). Search strategies were defined and performed in the MEDLINE/Pubmed, Embase, Epistemonikos and Google Scholar databases. The selection of articles followed the evidence hierarchy concept; evidence body was identified, and the quantitative study data were extracted. The quality of evidence and grade of recommendation were qualitatively assessed according to GRADE (Grading of Recommendations, Assessment, Development and Evaluations). Results: A total of 2.707 articles were identified, with 49 of them being selected to compose the basis for this review. Neurogenic bladder treatments were classified according to their focus on filling or emptying symptoms and sub- classified in pharmacological and surgical treatments. Conclusion: Treatment guidelines are important tools for the public health system to promote the best practice when treating neurogenic bladder patients.

Abstract
The present article is an abridged English translation of the Japanese Clinical Guidelines for Female Lower Urinary Tract Symptoms (second edition), published in September 2019. These guidelines consist of a total of 212 pages and are unique worldwide in that they cover female lower urinary tract symptoms other than urinary incontinence. They contain two algorithms for "primary treatment" and "specialized treatment," respectively. These guidelines, consisting of six chapters, address a total of 26 clinical questions including: (i) treatment algorithms; (ii) what are female lower urinary tract symptoms?; (iii) epidemiology and quality of life; (iv) pathology and illness; (v) diagnosis; and (vi) treatment. When the patient's symptoms mainly involve voiding and post-micturition symptoms, specialized treatment should be considered. In the event of voiding symptoms concurrent with storage symptoms, residual urine should be measured; if the residual urine volume is <100 mL, then diagnosis and treatment for storage symptoms is prioritized, and if the volume is ≥100 mL, then specialized treatment should be considered. When storage symptoms are the primary condition, then the patient is subject to the primary treatment algorithm. Specialized treatment for refractory overactive bladder includes botulinum toxin injection and sacral nerve stimulation. For stress urinary incontinence, surgical treatment is indicated, such as urethral slings. The two causes of voiding symptoms and post-micturition symptoms are lower urinary tract obstruction and detrusor underactivity (underactive bladder). Mechanical lower urinary tract obstruction, such as pelvic organ prolapse, is expected to improve with surgery.

Abstract
Objective This study retrospectively investigated the influence of urodynamic parameters and patient characteristics on success rates among patients with overactive bladder (OAB) and urodynamic detrusor overactivity (DO). Materials and Methods Consecutive patients with OAB and urodynamic DO initially received solifenacin, mirabegron, or combination of both for 1-3 months. If failed, patients were switched to another OAB medication subtype or provided additional OAB medication for a total of 6 months. A successful treatment was defined as an improvement in urgency severity and a global response assessment of ≥1. Success rates after initial or modulated OAB medication were analyzed based on patient and urodynamic characteristics. Results A total of 453 patients were enrolled, among whom 144, 255, and 54 received solifenacin, mirabegron, and combined medications, respectively. Among the patients, 259 (57.2%) had OAB dry and 194 (42.8%) had OAB wet. Patients receiving mirabegron alone had a significantly higher initial medication success rate compared to that of others. Patients with a phasic DO (50.7%), bladder outlet obstruction (BOO, 52.5%), and no central nervous system (CNS) lesions (47.5%) exhibited higher success rates than those with a terminal DO (42.0%), no BOO (42.7%), and CNS lesions (31.6%), respectively. After switching or modulating the initial OAB medication following treatment failure, 115 (62.2%) of 185 patients still showed improvement in OAB symptoms, with an overall success rate of 70.2% after 6 months of treatment. Conclusion Initial solifenacin or mirabegron treatment had a success rate of around 50%. In general, patients with a phasic DO, urodynamic BOO, and no CNS lesions have higher success rates than those with a terminal DO, no BOO, and CNS lesions, respectively. Success rates can further be improved by switching or modulating OAB medication.

Abstract
AIMS This study aimed to investigate the efficacy and safety of mirabegron for Parkinsonism patients with overactive bladder (OAB) symptoms in a randomized, placebo-controlled, multicenter study. MATERIALS AND METHODS Inclusion criteria are Parkinsonism with OAB symptoms for 4 weeks or more, OAB symptom score (OABSS) questionnaire scores greater than 2, and OABSS urgency question scores greater than 1. After a 2-week wash-out period, the patients were randomized into placebo and mirabegron groups at visit 2. Visit 3 was performed after 4 weeks of medication. Mirabegron was prescribed to the two groups for the rest of the study period at visit 4. RESULT The mean age was 68.1 ± 8.1 years and 72 males and 64 females were included. A total of 136 patients were screened, 117 patients were randomized, and 25 patients dropped out. The OABSS scores were significantly different between the two groups at Weeks 4 and 8. The OABSS scores became the same in the two groups at Week 12 (visit 5). The postvoid residual urine volume showed a mild increase to 64 ml in the mirabegron group compared to the placebo group at visit 4. Adverse events occurred in 27 patients (23.1%). The degree was mild in 26 cases (78.8%), moderate in five (15.2%), and severe in two (6.1%). Only 13 cases (39.4%) showed medication-related adverse events. Acute urinary retention occurred in a single case. The treatment satisfaction questionnaires showed no significant differences between the two groups. CONCLUSION Mirabegron was effective in treating OAB symptoms in patients with Parkinsonism with acceptable adverse events.

Abstract
PURPOSE To evaluate the use of mirabegron in patients with neurogenic bladder. METHODS A systematic review of the literature was conducted using four databases (Medline via PubMed, Scopus, Cochrane, and EMBASE). Articles evaluating mirabegron in neurogenic bladder patients were collected, and assessment of the drug's efficacy was reviewed according to clinical and urodynamic parameters. RESULTS Seven studies were selected and a total of 302 patients with NB were evaluated, ranging from 15 to 66 patients per study. All of the patients had received antimuscarinics as a previous treatment modality. Mirabegron was used as a second-line treatment after antimuscarinics lacked efficacy or caused adverse effects. The duration of the treatments ranged from 4 to 12 weeks. Reported in two studies each, bladder compliance and maximal cystometric capacity were the most commonly improved urodynamic parameters. In the majority of the studies, positive outcomes were reported for clinical scores. Additionally, analysis of the IPSS subscores revealed an improvement of storage symptoms as opposed to voiding symptoms. In all of the studies, mirabegron was well tolerated. CONCLUSION Mirabegron appears to be an effective treatment in the management of neurogenic bladder unresponsive to antimuscarinics, particularly in patients presenting with storage symptoms. There is still no evidence concerning the use of mirabegron as a first-line therapy for neurogenic bladder.

Ther Adv Neurol Disord 2019; 12:1756286419843458. [PMID: 31156718 PMCID: PMC6515844 DOI: 10.1177/1756286419843458] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2018] [Accepted: 03/19/2019] [Indexed: 12/23/2022] Open
Abstract
Background: We investigated the effectiveness and safety of mirabegron oral treatment in a group of patients with Parkinson’s disease (PD) and overactive bladder (OAB), refractory to antimuscarinics. Materials and methods: Thirty patients with PD and refractory OAB were prospectively included in the study. At baseline, motor symptoms, severity of disease and cognitive status were assessed with the Hoehn–Yahr Scale, the Unified Parkinson’s disease Rating Scale, the Mini Mental State examination and the Montreal Cognitive Assessment. At baseline, urinary symptoms, satisfaction with treatment and the impact of urinary incontinence on quality of life (QoL) were assessed with the 3-day voiding diary, the Visual Analogue Scale (VAS), the Incontinence–QoL questionnaire and urodynamics. Patients started assuming mirabegron 50 mg tablets once daily. Evaluation of urinary symptoms and related questionnaires, motor symptoms, severity of PD and uroflowmetry with postvoid residual volume measurement were then repeated at the 3- and 6-month follow up. Side effects were also noted. Results: At baseline, the most frequently reported urinary symptoms were: urinary urgency (present in all the patients), urge urinary incontinence in 28/30 (93.3%) and increased daytime urinary frequency in 25 (83.3%) patients. At the 3-month follow up, 7 out of the 30 patients achieved a complete urinary continence. Significant improvements in VAS and Incontinence–QoL scores were observed in 24 patients. These benefits were maintained for the whole observation period. Four patients discontinued treatment due to poor efficacy, and two due to the cost of the drug. Conclusions: Mirabegron is a safe and effective treatment in patients with PD and OAB refractory to anticholinergics in the short-term follow up.

Abstract
Overactive bladder (OAB) syndrome is highly prevalent in both men and women and might have negative impact on quality of life. Clinical trials of OAB usually highly select participants that may not reflect the real-world practice of OAB patients. The spectrum of OAB includes patients with idiopathic, neuropathic, with bladder outlet obstruction, and patients in elderly and medical comorbidities. Patients might have poor response to OAB medication or have adverse events after treatment. Therefore, treatment of OAB should be individualized to obtain therapeutic efficacy and avoid unacceptable adverse events. This article reviews the recently published literature and provides a guide for physicians to choose the appropriate treatment for different OAB patients.

Abstract
AIMS To determine the effectiveness of mirabegron in patients with neurogenic lower urinary tract dysfunction. METHODS Randomized, double-blind, placebo-controlled study. Canadian patients with spinal cord injury (SCI) or multiple sclerosis (MS) with urinary symptoms and incontinence were recruited. Patients were randomized to mirabegron 25 mg (or an identical placebo) for 2 weeks at which point a dose escalation to mirabegron 50 mg (or an identical placebo) was maintained for 8 weeks. Urodynamics were performed before and after treatment. The primary outcome measure was maximum cystometric capacity (MCC). Intention to treat analysis and ANCOVA models (with adjustment for baseline values) were used and marginal means (MM) are reported; P-value <0.05 was considered significant. RESULTS Sixteen (9 SCI and 7 MS) patients were randomized to mirabegron and 16 (10 SCI and 6 MS) to placebo. At study completion, there was no significant difference in MCC between mirabegron and placebo (MM 305 vs 369 mL, P = 0.20). There was no significant difference in volume at first neurogenic detrusor overactivity (NDO, MM 167 vs 137 mL, P = 0.14) and peak pressure of NDO (MM 69 vs 82 cmH2 O, P = 0.25). There was no significant difference in pad weights or voiding diary parameters. There was a significantly lower symptom burden among those treated with mirabegron (total neurogenic bladder symptom score MM 29 vs 34, P = 0.047). CONCLUSIONS Among patients with SCI or MS, we demonstrated non-significant trends towards improvement in some urodynamic parameters with mirabegron 50 mg compared to placebo, and a significantly lower neurogenic bladder symptom burden.
