RESUMEN
Introduction: Overactive bladder (OAB) is a highly prevalent condition with limited treatment options due to poor efficacy, side effects, and patient compliance. Novel drug delivery systems that can target the bladder wall may improve OAB therapy. Methods: We explored a polydopamine (PDA)-coated lactobacillus platform as a potential carrier for localized OAB treatment. Urinary microbiome profiling was performed to identify the presence of lactobacillus in healthy and OAB groups. Lactobacillus-PDA nanoparticles were synthesized and characterized by electron microscopy and spectrophotometry. A rat bladder perfusion model and human bladder smooth muscle cell spheroids were used to assess the distribution and penetration of the nanoparticles. The efficacy of the Lactobacillus-PDA system (LPS) for delivering the antimuscarinic drug solifenacin was evaluated in an OAB rat model. Results: Urinary microbiome profiling revealed lactobacillus as a dominant genus in both healthy and OAB groups. The synthesized Lactobacillus-PDA nanoparticles exhibited uniform size and optical properties. In the rat bladder perfusion model, the nanoparticles distributed throughout the bladder wall and smooth muscle without toxicity. The nanoparticles also penetrated human bladder smooth muscle cell spheroids. In the OAB rat model, LPS facilitated the delivery of solifenacin and improved treatment efficacy. Discussion: The results highlight LPS as a promising drug carrier for targeted OAB therapy via penetration into bladder tissues. This bacteriotherapy approach may overcome limitations of current systemic OAB medications. Lactobacillus, a probiotic bacterium present in the urinary tract microbiome, was hypothesized to adhere to and penetrate the bladder wall when coated with PDA nanoparticles, making it a suitable candidate for localized drug delivery.

OBJECTIVES: Multiple sclerosis (MS) is a chronic neuroinflammatory and neurodegenerative progressive disease of central nervous system that mostly affects young adults. (1) Because of involvement of spinal cord and brain, lower urinary dysfunction symptoms are commonly encountered. MS patients mostly show overactive bladder symptoms like urgency, frequent daytime urination, and urgency incontinence. Among MS patients, antimuscarinic therapy is the first-line treatment with overactive bladder symptoms as well as in general population yet 30% of the patients show insufficient improvement or intolerance to the treatment (2). In our study, our aim is to evaluate the efficacy and safety of mirabegron add-on treatment in MS patients after inadequate response to antimuscarinic monotherapy. METHODS: University of Kyrenia and Dr Burhan Nalbantoglu State hospital's databases were screened for the study. Seventy patients who were residents diagnosed with MS according to McDonald criteria were questioned. Among these patients, a total of 22 of them were included in the study. Inclusion criteria was at least 3 years of MS diagnosis, score of <6 at Expanded Disability Status Scale, and a score of ≥3 at Overactive Bladder Symptom Score Scale. RESULTS: Among selected patients, 10 mg solifenacin treatment was daily started and followed for 4 weeks. Mirabegron add-on treatment was initiated to the 11 patient who had inadequate improvement in overactive bladder symptom score. After mirabegron add-on treatment among 11 patient, there was a sufficient improvement in overactive bladder symptom score ( P < 0.008). CONCLUSIONS: In our study, we have found that antimuscarinic and mirabegron combination causes improved efficacy for overactive bladder in MS population.

Solifenacin (SFC) is a potent muscarinic antagonist that effectively reduces bladder muscle contraction, thereby alleviating symptoms such as frequency of micturition and urgency. Oxidation of SFC leads to the formation of impurities like Impurity K. Effective analysis and control of this impurity is crucial for ensuring compliance with regulatory standards and safeguarding patient health. To address these challenges, we propose a novel one-step synthesis of Impurity K from SFC. Impurity K was synthesized using cerium(IV) ammonium nitrate (CAN) in water/acetonitrile as the solvent. Additionally, we describe a new HPLC-MS method for the detection of Impurity K in solifenacin succinate tablets.

BACKGROUND: Overactive bladder is a common chronic urological disorder in children, liable to impact normal social activities, disrupt sleep and even impair self-esteem. We aimed to evaluate the efficacy and safety of solifenacin combined with biofeedback for paediatric overactive bladder. METHOD: Forty-five children with overactive bladder were enrolled and divided into three groups: 15 patients in Group A were treated with solifenacin, 15 cases in Group B with biofeedback, and the other 15 patients in Group C with the combination of solifenacin plus biofeedback. Each group was subdivided into the non-urge incontinence (non-UI) and urge incontinence (UI) groups. The remission rates were compared among the three groups at 2, 4, 8 and 12 weeks from the beginning of treatment. The side effects of solifenacin were recorded and followed up. RESULT: After 2 weeks since initial treatment, the complete response rates were 33.3% (5/15), 20.0% (3/15), and 53.3% (8/15) in the three groups. At 4 weeks, the complete remission rates were 46.7% (7/15), 33.3% (5/15), and 60.0% (9/15) respectively. Moreover, the complete remission rates of the UI groups were higher than the non-UI groups (p < 0.05). At 8 weeks, the complete response rates were 53.3% (8/15), 40.0% (6/15), and 67.7% (10/15). At 12 weeks, the complete response rates were 67.8% (10/15), 60.0% (9/15), and 86.7% (13/15). The complete response rates were higher and urodynamic parameters were improved obviously in group C than the other two groups (p < 0.05) during the follow-ups. The median voiding frequency decreased and median functional bladder capacity increased obviously in Group C after 4 weeks (p < 0.05). Dry mouth was observed in 2 patients (4.4%). 2 patients experienced constipation (4.4%), and neither case was severe. The symptoms of these four patients had relieved by reducing the dose of solifenacin. CONCLUSION: Solifenacin combined with biofeedback had good efficacy and compliance for children experiencing overactive bladder. It took only 2 weeks to achieve the complete response rate over 50%, especially for the improvement of UI symptoms.

INTRODUCTION: This study aimed to assess overactive bladder (OAB) treatment patterns and factors associated with effectiveness and persistence. METHODS: A prospective, longitudinal, observational registry study of adults starting OAB therapy with mirabegron or antimuscarinics was undertaken. Primary endpoints were time from treatment initiation to discontinuation/switching; proportion who discontinued/switched; and reasons for discontinuation/switching. Secondary endpoints included OAB Symptom Score (OABSS), OAB Questionnaire: Short Form, and OAB Bladder Assessment Tool scores; factors associated with effectiveness and persistence; and safety. RESULTS: In total, 556 patients initiating mirabegron and 250 initiating antimuscarinics were enrolled. There was no treatment switch, change, or discontinuation in 68.5% of the mirabegron initiator group and median time to treatment change was not reached. Mean initial treatment duration was 130.8 days. In multivariable models, baseline OABSS was the only variable significantly associated with change from baseline in OABSS, and patients with mild and moderate OAB had significantly better persistence with mirabegron than those with severe OAB. Urinary tract infection was the most common adverse event with mirabegron. There was no treatment switch, change, or discontinuation in 60.4% of the antimuscarinics initiator group and median time to treatment change was not reached. Solifenacin was the most frequent initial treatment (66.0%). Mean treatment duration was 122.2 days. In multivariable models, baseline OABSS was the only variable significantly associated with change from baseline in OABSS, while patients with OAB medication in the 12 months before enrollment had significantly better persistence with antimuscarinics than those with no previous OAB medication. Dry mouth was the most common adverse event with antimuscarinics. CONCLUSIONS: Mirabegron and solifenacin were commonly prescribed as first-line OAB medications. There was no treatment switch, change, or discontinuation in more than 60% of the mirabegron initiator and antimuscarinics initiator groups. Mean initial treatment duration was 130.8 days and 122.2 days for mirabegron and antimuscarinics, respectively. Graphical Abstract available for this article.

BACKGROUND: Low-intensity shockwave therapy (Li-SWT) can improve bladder function through enhancement of angiogenesis and nerve regeneration and suppression of inflammation and overactivity. In this trial, we aimed to evaluate the efficacy of Li-SWT on persistent storage symptoms after transurethral surgery (TUS) for benign prostatic obstruction (BPO). METHODS: Between July 2020 and July 2022, 137 patients with persistent storage symptoms; urgency episodes/24 h ≥ 1 and daytime frequency ≥8, for at least three months after TUS for BPO were randomly allocated to Li-SWT versus sham versus solifenacin 10 mg/day in 3:1:1 ratio. The primary end point was the percent reduction from baseline in overactive bladder symptom score (OABSS) at 3-month follow-up. The changes in 3-day voiding diary parameters, quality of life (QoL) score, peak flow rate and residual urine at 3 and 6-month follow-up were compared. Treatment-related adverse effects were also evaluated. RESULTS: Baseline data were comparable between groups. The percent reduction from baseline in OABSS at 3-month follow-up was significantly higher in Li-SWT compared to sham (-55% versus -11%), and it was comparable between Li-SWT and solifenacin-10 (-55% versus -60%). Li-SWT achieved significant improvement like solifenacin-10 in 3-day voiding diary parameters and QoL score at 3-month follow-up. This improvement remained comparable between Li-SWT and solifenacin-10 at 6-month follow-up. No adverse effects related to Li-SWT were noted apart from tolerable pain during the procedure. Solifenacin-10 was associated with bothersome adverse effects in 73% of the patients with 11.5% discontinuation rate. CONCLUSIONS: Li-SWT ameliorates persistent storage symptoms and promotes QoL after TUS for BPO, with comparable efficacy and better tolerance compared to solifenacin.

IMPORTANCE: There is strong evidence for long-term cognitive effects with anticholinergic use. Differences in insurance coverage of anticholinergics and beta-3 agonists hinder individualization of overactive bladder (OAB) treatment. OBJECTIVES: The aims of the study were to assess individual and family health insurance plan coverage for select OAB medications and to compare coverage of preferred medications to those with a greater risk of cognitive dysfunction. STUDY DESIGN: This cross-sectional study analyzed formularies for the top 7 U.S. medical insurers. Coverage tiers were assessed for the following 7 OAB medications: (1) oxybutynin instant-release 5 mg, (2) oxybutynin extended-release 5 mg, (3) solifenacin 5 mg, (4) trospium instant-release 20 mg, (5) trospium extended-release 60 mg, (6) mirabegron 25 mg, and (7) vibegron 75 mg. Coverage was compared between nonpreferred (oxybutynin, solifenacin) and preferred medications (trospium, mirabegron, vibegron). Coverage scores, representing a weighted average based on coverage tier frequency relative to the number of plans investigated for each state or insurer, were generated with a lower coverage score indicating better coverage (range, 0.2-1.0). RESULTS: A total of 2,780 insurance plans from 41 states representing a 47% market share for the individual and family marketplace were evaluated. Oxybutynin IR had the best coverage score across insurers (0.2) while vibegron had the worst (0.92). Preferred medications were more often designated to higher tiers with worse coverage compared with nonpreferred medications (P < 0.001). Less concordance in coverage between insurers was noted for anticholinergics with greater bladder specificity and for extended-release formulations. CONCLUSIONS: Despite risks with anticholinergics, beta-3 agonists were more expensive across all insurers highlighting the need for expanded coverage of preferred medications to avoid cognitive dysfunction when undergoing treatment for OAB.

Persistence is important for the success in the treatment of women with overactive bladder syndrome (OAB). We aimed to identify the predictors of non-persistence in women with OAB after first-line medical treatment. All consecutive women with OAB (n = 608), who underwent urodynamic studies and received first-line medical treatment (5 mg of solifenacin or 25 mg of mirabegron per day) in a referral medical center, were reviewed. Mirabegron (hazard ratio [HR] = 0.711) was associated with a higher persistence rate, compared to solifenacin. Mirabegron treatment (HR = 0.269) was less likely to switch medication; however, a high Urogenital Distress Inventory score (HR = 1.082) was more likely to switch medication. Furthermore, old age (HR = 1.050, especially for ≥ 75 years) and high voided volume (dL, HR = 1.420, especially for voided volume ≥ 250 ml) were associated with added medication at follow-up. Additionally, women with low parity (HR = 0.653, especially for parity ≤ 3) and a low Incontinence Impact Questionnaire (IIQ-7) score (HR = 0.828, especially for IIQ-7 score ≤ 7) were associated with improvement without medication. In conclusion, mirabegron can be considered as the first frontline treatment to increase the persistence rate and decrease the rate of switched medications, compared to solifenacin. In addition, combination therapy or higher-dose monotherapy could be used as the first front-line treatment for women ≥ 75 years of age or with ≥ 250 ml of voided volume.

The R,S-enantiomer impurity and diastereomer impurities (S,S-isomer and R,R-isomer) of the solifenacin (S,R-enantiomer) were effectively separated and quantified simultaneously utilizing normal-phase high-performance liquid chromatography with a chiral stationary phase consisting of amylose tris (3,5-dimethylphenylcarbamate) coated on silica-gel (Chiralpak, AD-H). The enantiomeric and stereo-selective separation was achieved within a run time of 35 minutes using a mobile phase of 'n-hexane, ethanol, and diethylamine' in an isocratic elution mode with a detection wavelength of 220 nm. The validation attributes assessed were accuracy (which showed excellent recoveries between 97.5% and 100.4%) and linearity (which was proven in the range of 0.081-1.275 µg.mL-1 , with a linear regression of 0.999). The stress testing experiments proved that the developed methodology by the HPLC technique has stability-indicating characteristics, as all closely eluting peak pairs were separated well with a resolution of 2.3 and without any interference. The proposed methodology was highly efficient in separating and simultaneously determining the chiral impurities (enantiomers and diastereomers) of the solifenacin in the release and stability sample analyses of drug substances and tablets in pharmaceutical formulations.

Myelination subserves efficient neuronal communication, and alterations in white matter (WM) microstructure have been implicated in numerous psychiatric disorders, including pathological anxiety. Recent work in rodents suggests that muscarinic antagonists may enhance myelination with behavioral benefits; however, the neural and behavioral effects of muscarinic antagonists have yet to be explored in non-human primates (NHP). Here, as a potentially translatable therapeutic strategy for human pathological anxiety, we present data from a first-in-primate study exploring the effects of the muscarinic receptor antagonist solifenacin on anxious behaviors and WM microstructure. 12 preadolescent rhesus macaques (6 vehicle control, 6 experimental; 8F, 4M) were included in a pre-test/post-test between-group study design. The experimental group received solifenacin succinate for ~60 days. Subjects underwent pre- and post-assessments of: 1) anxious temperament (AT)-related behaviors in the potentially threatening no-eye-contact (NEC) paradigm (30-min); and 2) WM and regional brain metabolism imaging metrics, including diffusion tensor imaging (DTI), quantitative relaxometry (QR), and FDG-PET. In relation to anxiety-related behaviors expressed during the NEC, significant Group (vehicle control vs. solifenacin) by Session (pre vs. post) interactions were found for freezing, cooing, and locomotion. Compared to vehicle controls, solifenacin-treated subjects exhibited effects consistent with reduced anxiety, specifically decreased freezing duration, increased locomotion duration, and increased cooing frequency. Furthermore, the Group-by-Session-by-Sex interaction indicated that these effects occurred predominantly in the males. Exploratory whole-brain voxelwise analyses of post-minus-pre differences in DTI, QR, and FDG-PET metrics revealed some solifenacin-related changes in WM microstructure and brain metabolism. These findings in NHPs support the further investigation of the utility of antimuscarinic agents in targeting WM microstructure as a means to treat pathological anxiety.

PURPOSE: We investigated the efficacy and safety of high-dose vitamin D supplementation (VDS) plus standard urotherapy (SU) in managing overactive bladder dry in children. MATERIALS AND METHODS: A 3-arm, randomized clinical trial was performed at an academic center in China between January 2023 and June 2023. Eligible patients (n=303) were randomized to receive 8 weeks of high-dose VDS (vitamin D3 drops encapsulated as soft capsules, 2400 IU/d) plus SU (VDS + SU group; n=100), solifenacin (5-10 mg/d) plus SU (SOL + SU group; n=102), or SU alone (SU group; n=101). Reduction in voiding frequency was the primary outcome. Secondary outcomes encompassed improvement in urgency, nocturia, quality of life score, pediatric lower urinary tract symptom score, and participant satisfaction. Treatment-emergent adverse events were recorded within each group. RESULTS: Participants had a median age of 82.0 months and their baseline mean vitamin D level was 22.64 ng/mL. The VDS + SU group showed greater improvements in voids/d than the SOL + SU group (median difference 3.0; 95% CI, 2.0 to 3.5; P < .001) and the SU group (median difference 4.0; 95% CI, 3.0 to 5.0; P < .001) after intervention. The VDS + SU group also showed the greatest improvement in quality of life and pediatric lower urinary tract symptom scores. Patient satisfaction was similar between the SOL + SU and SU groups. The VDS + SU group did not exhibit a heightened risk of treatment-emergent adverse events compared to the other groups. CONCLUSIONS: High-dose VDS plus SU was effective and well-tolerated in managing overactive bladder dry in children, suggesting its potential as a novel therapeutic option for this population.

Demyelinating diseases are a type of neurological disorder characterized by the damage to the myelin sheath in the central nervous system. Promoting the proliferation and differentiation of oligodendrocyte precursor cells (OPCs) is crucial for treatment. Non-selective muscarinic receptor (MR) antagonists have been shown to improve remyelination in rodent models, although the mechanisms are still unclear. In this study, we treated cuprizone (CPZ)-induced demyelination mouse model with different concentrations of Solifenacin (Sol), a selective M3 receptor antagonist, to determine the optimal concentration for promoting remyelination. Behavioral tests and Luxol fast blue (LFB) staining were used to observe the extent of remyelination, while immunofluorescence was used to measure the expression levels of myelin-related proteins, including myelin basic protein (MBP) and platelet-derived growth factor receptor alpha (PDGFR-α). Western blot analysis was employed to analyze the expression levels of molecules associated with the Wnt/ß-catenin signaling pathway. The results showed that Sol treatment significantly promoted myelin regeneration and OPCs differentiation in CPZ-induced demyelination mouse model. Additionally, Sol treatment inhibited the Wnt/ß-catenin signaling pathway and reversed the effects of CPZ on OPCs differentiation. In conclusion, Sol may promote the differentiation of OPCs by inhibiting the Wnt/ß-catenin signaling pathway, making it a potential therapeutic option for central nervous system demyelinating diseases.

OBJECTIVE: The aim: To improve the results of treatment of hyperactive bladder syndrome in men of working age on the background of barotrauma and stress, as a consequence of combat trauma. PATIENTS AND METHODS: Materials and methods: An analysis of the questionnaire and the results of the clinical examination of 32 patients, injured servicemen and people who were injured in combat zones was carried out. The drug solifenacin succinate was used in the treatment complex, which is a specific antagonist of M3 subtype cholinergic receptors. Its influence allows you to achieve relaxation of the bladder detrusor and reduce the contractility of hyperactive bladder. RESULTS: Results: The main criterion for the effectiveness of the treatment was a decrease in the number of urgent cases, the frequency of urination and manifestations of nocturia by 50% or more, which was considered a positive effect. At the same time, the positive effect was differentiated as follows : an improvement of these parameters by 75% or more from the initial value which is a good result; reduction of symptoms in the range of 50-75% is satisfactory; less than 50% is an unsatisfactory result. A positive effect from the treatment after 8 weeks was observed in 88% of patients, of which 52% had a good result and 36% had a satisfactory result. CONCLUSION: Conclusions: The proposed complex of treatment of hyperactive bladder syndrome as a result of combat trauma against the background of barotrauma with neurological consequences and chronic stress allows to achieve a pronounced clinical effect in the vast majority of male patients of working age. And the diagnostic complex allows you to emphasize aspects of clinical vigilance, both for doctors of a specialized branch and of doctors of a general direction.

Introduction: ureteral stents have common complications like ureteral stent-related symptoms (SRSs). This study investigated the effectiveness of tadalafil compared to mirabegron and solifenacin combination therapy in patients with ureteral SRSs after double-J (DJ) stent insertion. Methods: this double-blind, randomized clinical trial used consecutive random sampling in participants with SRSs after double-J stent insertion. The study was conducted at four different hospitals in Makassar, Indonesia, from July to December 2020. Ureteral stent-related morbidity indices which analyzed include urinary symptoms, pain, general health, quality of work, and sex scores. All of the indices were measured by ureteral symptom score questionnaire for the first, second, third, and fourth weeks after drug consumption, either tadalafil 10 mg/day (group A, n=25) and a combination of mirabegron 25 mg/day and solifenacin 5 mg/day (group B, n=28). Results: before the treatment procedure, the groups were comparable in age, gender, body mass index, DJ stent procedures, type, and indication. In general, the score in all parameters declined over the follow-up time for both groups. Group A had a lower urinary symptom score than group B at week III and week IV (all p-value < 0.001). In addition, group A had a lower pain score, general condition, work activity, and other complaints than group B at week II, week III, and week IV (all p-value <0.001). The sexual activity score is comparable between the group, except in week I. Conclusion: according to our results, we suggest tadalafil to minimize stent-related urinary symptoms and improve general health in patients with double J stent.

The purpose of this article is to review the effects of different types of pharmacotherapy on symptoms that affect the quality of a patient's life after stent insertion. A thorough Medline/PubMed nonsystematic review was conducted from 1987 to January 2023, using the terms: "pigtail" OR "ureteral stents" AND "lower urinary tracts symptoms" OR "LUTS" AND "pharmacotherapy" OR "drugs". Relevant studies conducted in humans and reported in English language were included. The available reviews and articles associating the use of drugs with stent-related symptoms (SRS) provide conflicting results. Most of them show a clear benefit of alpha blockers, particularly alfuzosin, on treating urinary SRS, and hence there is a strong recommendation for the use of alpha blockers for the treatment of SRS in the guidelines of the European Association of Urology. Anticholinergics and mirabegron have shown a significant benefit in dealing with irritative bladder symptoms. In contrast, the findings for combination therapies are contradictory, with some studies showing that combination therapy is no superior to monotherapy with regards to most of the subsets of the Ureteral Stent Symptom Questionnaire (USSQ), whereas others present a clear benefit of combination therapies, specifically silodosin and solifenacin, in treating stent-associated lower urinary tract symptoms (LUTS), in comparison with any other type of monotherapy or combination therapy. Many studies suggest that some categories of pharmacotherapy, such as alpha blockers, can alleviate SRS. However, there is conflicting evidence concerning most other types of medical treatment. Randomized trials with the largest number of patients are needed to investigate the effectiveness of novel approaches on SRS.

bladder based on a systematic review and network meta-analysis approach. METHODS: Pubmed, Embase, Web of Science, and the Cochrane Register of Clinical Trials databases were systematically searched. The search time frame was from database creation to June 2, 2022. Randomized controlled double-blind trials of oral medication for overactive bladder were screened against the protocol's entry criteria. Trials were evaluated for quality using the Cochrane Risk of Bias Assessment Tool, and data were statistically analyzed using Stata 16.0 software. RESULT: A total of 60 randomized controlled double-blind clinical trials were included involving 50,333 subjects. Solifenacin 10mg was the most effective in mean daily micturitions and incontinence episodes, solifenacin 5/10mg in mean daily urinary urgency episodes and nocturia episodes, fesoterodine 8mg in urgency incontinence episodes/d and oxybutynin 5mg in voided volume/micturition. In terms of safety, solifenacin 5mg, ER-tolterodine 4mg, mirabegron, vibegron and ER-oxybutynin 10mg all showed a better incidence of dry mouth, fesoterodine 4mg, ER-oxybutynin 10mg, tolterodine 2mg, and vibegron in the incidence of constipation. Compared to placebo, imidafenacin 0.1mg showed a significantly increased incidence in hypertension, solifenacin 10mg in urinary tract infection, fesoterodine 4/8mg and darifenacin 15mg in headache. CONCLUSION: Solifenacin showed better efficacy. For safety, most anticholinergic drugs were more likely to cause dry mouth and constipation, lower doses were better tolerated. The choice of drugs should be tailored to the patient's specific situation to find the best balance between efficacy and safety.

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

PURPOSE: Ureteral stents are commonly used for the treatment of ureteral obstruction, most often urolithiasis. Their use may be associated with significant bothersome symptoms and discomfort. Prior studies have examined the effects of various medication regimens on ureteral stent symptoms. This study utilized Bayesian network meta-analysis to analyze all available evidence on the pharmacological management of ureteral stent-related symptoms. MATERIALS AND METHODS: In December 2022 a systematic review was conducted following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines on randomized prospective studies on pharmacological management of ureteral stent-related symptoms reporting outcomes using the Ureteral Stent Symptom Questionnaire score on urinary symptoms and pain. The data were analyzed in Review Manager 5.3 and R Studio where a Bayesian network meta-analysis was performed. Treatments were ranked using surface under the cumulative ranking curve and mean difference vs placebo with 95% credible intervals. RESULTS: A total of 26 studies were analyzed. These were used to build networks which were modeled to run 100,000 Markov Chain Montecarlo simulations each. Drug-class analysis revealed the most effective class for each domain: for urinary symptoms, sexual performance, general health, and work performance-combined α-blocker and anticholinergic and phosphodiesterase 5 inhibitors; for pain-combined anticholinergic and pregabalin. The following were the most effective drugs and dosages for specific symptoms: for urinary symptoms-combined silodosin 8 mg+solifenacin 10 mg; for pain-combined silodosin 8 mg+solifenacin 10 mg; for sexual performance-tadalafil 5 mg. Combined silodosin 8 mg+solifenacin 10 mg+tadalafil 5 mg has the best general health scores while solifenacin 10 mg had the best work experience scores. CONCLUSIONS: This network meta-analysis demonstrated that the most effective drug therapy is different for each symptom domain. It is important to consider a patient's chief complaint and domains in order to ascertain the optimal medication regimen for each patient. Further iterations of this analysis can be strengthened by trials that directly compare more of these drugs instead of relying on indirect evidence.

PURPOSE: To assess the prescribing practices for overactive bladder (OAB) pharmacotherapy based on the prescription trend analysis across different specialties of India. METHOD: s: IQVIA (Quintiles and IMS Health) secondary sales audit (SSA), as well as a prescription audit for antimuscarinics and beta-3 adrenoceptor agonists (mirabegron) from 2014 to 2021, were analyzed. The data includes SSA data of various antimuscarinics like solifenacin, oxybutynin, tolterodine, darifenacin, trospium and mirabegron change in the prescription trend of antimuscarinics and mirabegron across different specialties; prescribers overlap analysis for solifenacin and mirabegron among Indian urologists were also analyzed. RESULTS: Urologists prescription rates of OAB drugs were 65% in 2016 and 54% in 2021. The rate of OAB medication prescription by non-urologist was highest from the surgeon (11%), followed by gynecologists (9%) and consultant physicians (8%) in 2021. In addition, among OAB medication prescription rates for antimuscarinics were 100% in 2016 and 58% in 2021 whereas for mirabegron, it was 0% in 2016 and 42% in 2021. Solifenacin was most frequently prescribed anticholinergics, followed by oxybutynin, tolterodine, darifenacin, and trospium. The proportion of prescribers of OAB medication among urologists was 38% in 2016 and 33% in 2021. Exclusive prescribers of solifenacin were 748 in 2018 and 739 in 2021 at the urologist, whereas for mirabegron, it was 961 in 2018 and 934 in 2021. The compound annual growth rate for prescription of the last 6 years (from 2016-2021) for solifenacin and mirabegron was -3% and 8% respectively. CONCLUSIONS: Urology remained a top prescribing specialty for OAB drugs, although prescription share increased at surgeon and consultant physician. OAB medicines prescriptions by urologists are shifting from leading antimuscarinic solifenacin to beta-agonist mirabegron. Data from this study will ultimately lead to the OAB medication preference by the specialist that could lead to more advanced OAB management.
