PURPOSE: We performed a meta-analysis to evaluate the efficacy and safety of mirabegron add-on therapy to solifenacin for patients with overactive bladder (OAB). METHODS: We conducted a systematic literature review to identify all randomized, double-blind, controlled trials (RCTs) of this combination (mirabegron and solifenacin) for OAB. Embase, MEDLINE, and the Cochrane Central Register of Controlled Trials were searched. A manual search was also performed to investigate relevant references from the retrieved studies. RESULTS: Four publications describing 5 RCTs that compared combination therapy with solifenacin, including a total of 3,309 patients, were analyzed. The mean number of micturitions per 24 hours (mean difference [MD], -0.45; 95% confidence interval [CI], -0.65 to -0.26; P < 0.00001), number of episodes of incontinence per 24 hours (MD, -0.71; 95% CI, -0.14 to -0.02; P=0.04), volume voided per micturition, and number of urgency episodes per 24 hours demonstrated that combination therapy was more effective than solifenacin therapy alone. Safety assessments, including common treatment-emergent adverse events (odds ratio, 1.09; 95% CI, 0.95–1.27; P=0.23) and discontinuations due to adverse events (P=0.30), demonstrated that the combination therapy was well tolerated. CONCLUSIONS: This meta-analysis suggests that mirabegron therapy as an add-on to solifenacin provides a satisfactory therapeutic effect for OAB symptoms with a low occurrence of side effects.

We investigated the efficacy and tolerability of solifenacin 5 mg fixed dose in children with newly diagnosed idiopathic overactive bladder (OAB). A total of 34 children (male/female patients = 16/18) aged under 13 years (mean age: 7.2 ± 2.3; range: 5–12) who were newly diagnosed with OAB from January 2012 to September 2014 were prospectively evaluated with open-label protocol. All patients were treated with solifenacin 5 mg fixed dose once daily for at least 4 weeks. The efficacy and tolerability of solifenacin were evaluated 4, 8, and 12 weeks after the initiation of treatment. The mean voiding frequency during daytime was decreased from 9.4 ± 3.0 to 6.5 ± 2.3 times after the 12-week treatment (P < 0.001). The mean total OAB symptom score (OABSS) decreased from 7.7 ± 4.2 to 3.1 ± 3.1 after the 12-week treatment (P < 0.001). The urgency and urgency urinary incontinence (UUI) domains significantly improved from the 12-week treatment, and complete resolution of urgency occurred in 38.9% of patients and the percentage of children with UUI among urgent patients decreased from 79.4% to 57.1%. According to 3-day voiding diaries, the average bladder capacity increased from 90.4 ± 44.4 to 156.2 ± 67.3 mL (P < 0.001). Drug-induced adverse effects (AEs) were reported in 7 patients (20.6%). Our results indicate that solifenacin 5 mg fixed dose is effective against OAB symptoms, and its tolerability is acceptable without significant AEs in children with OAB.

PURPOSE: The aim of this study was to evaluate the effect of desmopressin combined with anticholinergics on daytime frequency and urgency in female patients with overactive bladder (OAB). MATERIALS AND METHODS: We included 68 female patients with OAB. Patients were randomly assigned to receive 5 mg of solifenacin (group I) or 5 mg of solifenacin and 0.2 mg of desmopressin (group II) for 2 weeks. A pre/post-treatment 3-day voiding diary and the Urinary Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7) were used to assess changes in voiding symptoms and quality of life (QoL); results were compared between the two groups. RESULTS: Groups I and II included 31 and 37 patients, respectively. Time to first void was 12 min later in group II (105 min vs. 117 min), but this difference was not statistically significant. However, time to the second and third voids (203 min vs. 255 min, 312 min vs. 368 min) and the first urgency episode (212 min vs. 255 min) were significantly longer in group II. Compared with group I, patients in group II showed significant improvement in QoL scores. When improvement after treatment was defined as increase in time to first void of greater than 10% after 2 weeks of treatment, desmopressin with anticholinergics was more effective in patients over the age of 65 years and with more than 150 ml of voided volume. CONCLUSIONS: Desmopressin combined with anticholinergics was more effective than anticholinergics only in the treatment of female patients with OAB.

Overactive bladder is a chronic condition defined by bothersome urgency with or without urgency incontinence, usually associated with daytime frequency and nocturia. The treatment of this condition is to control bothersome urinary symptoms and is therefore to improve quality of life. The Korean Continence Society published the overactive bladder guideline in 2007, which suggested the mainstay of management is behavioral therapy and antimuscarinic pharmacotherapy. With growing awareness toward overactive bladder and quality of life, clinical information regarding antimuscarinic agents should be updated. There are several agents with good level of evidence and good grade of recommendation. Newer antimuscarinic agents are available or will be available in near future. The pharmacological properties, efficacy and tolerability of oxybutynin, trospium, propiverine, tolterodine, darifenacin, solifenacin, fesoterodine and imidafenacin are reviewed and discussed here. The results of major clinical studies are summarized.

PURPOSE: To determine the baseline clinical characteristics associated with dose escalation of solifenacin in patients with overactive bladder (OAB). METHODS: We analyzed the data of patients with OAB (micturition frequency > or =8/day and urgency > or =1/day) who were treated with solifenacin and followed up for 24 weeks. According to our department protocol, all the patients kept voiding diaries, and OAB symptom scores (OABSS) were monitored at baseline and after 4, 12, and 24 weeks of solifenacin treatment. RESULTS: In total, 68 patients (mean age, 60.8+/-10.0 years) were recruited. The dose escalation rate by the end of the study was 41.2%, from 23.5% at 4 weeks and 17.6% at 12 weeks. At baseline, the dose escalator group had significantly more OAB wet patients (53.6% vs. 20.0%) and higher total OABSS (10.2+/-2.4 vs. 7.9+/-3.5, P=0.032) than the nonescalator group. OAB wet (odds ratio [OR], 4.615; 95% confidence interval [CI], 1.578-13.499; P<0.05) and total OABSS (OR, 1.398; 95% CI, 1.046-1.869; P<0.05) were found to be independently associated with dose escalation. CONCLUSIONS: Patients who have urgency urinary incontinence and high total OABSS have a tendency for dose escalation of solifenacin.

PURPOSE: We investigated improvements in overactive bladder symptoms and depressive symptoms after solifenacin treatment in overactive bladder patients with or without depressive symptoms. METHODS: We performed a prospective study of patients who had been diagnosed with overactive bladder from July 2013 to June 2014. Based on the Beck Depression Inventory questionnaire, the test subjects were divided into group 1, without depressive symptoms (0–9 points), and group 2, with depressive symptoms (10 or more points). The patients were administered 5 mg of solifenacin for 3 months. The following outcomes were analyzed at the first visit, 4 weeks, and 12 weeks: the overactive bladder symptom score (OABSS), International Prostate Symptom Score (IPSS), patients’ perceptions of their bladder condition, and the Beck Depression Inventory. RESULTS: A total of 72 patients participated, and 52 patients completed the study. Most outcome measures showed improvements in both groups at weeks 4 and 12. Especially in group 2, the questionnaires showed significant improvements from baseline to week 12, indicating that solifenacin was effective at treating overactive bladder symptoms (group 1 vs. group 2: OABSS, −2.67±0.80 vs. −3.00±0.77; P<0.01; IPSS-total, −2.14±2.15 vs. −4.94±1.70; P<0.01). Statistically significant decreases in the Beck Depression Inventory score from baseline to weeks 4 and 12 were observed in group 2 (group 1 vs. group 2: 1.43±0.74 vs. −2.68±4.05 at week 4, P<0.001; 0.10±3.37 vs. −5.52±5.82 at week 12, P<0.001). CONCLUSIONS: In overactive bladder patients with depressive symptoms, solifenacin can help improve quality of life and depressive symptoms at the same time.

We compared changes in nocturia and sleep-related parameters between daytime and nighttime solifenacin dosing in patents with overactive bladder (OAB) and nocturia. We comparatively analyzed the data of a 12-week prospective, open-label, multicenter, randomized study. All 127 patients who presented to 5 centers in Korea for the treatment of OAB with nocturia between January 2011 and December 2013 were enrolled in this study. The patients were divided into 2 groups by medication timing: group 1, daytime (n = 62); and group 2, nighttime (n = 65). The International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), and Athens Insomnia Scale (AIS) were used to assess OAB symptoms and sleep quality. We evaluated the parameter changes before and 12 weeks after daytime or nighttime solifenacin administration. Baseline data, which included sex, age, body mass index (BMI), total AIS, IPSS, and OABSS, did not differ between the 2 groups. Total IPSS, OABSS, and total AIS significantly improved after solifenacin administration regardless of timing (P < 0.001). After solifenacin administration, the number of nocturia episodes decreased in the group 1 and 2 (P < 0.001). There were no significant intergroup differences in changes in AIS, IPSS, OABSS, and number of nocturia episodes 12 weeks after solifenacin administration. Treating OAB with solifenacin may improve nocturia and sleep quality, but advantages did not differ significantly by medication timing.

PURPOSE: To evaluate the effect of tamsulosin, solifenacin, and combination therapy of two agents in improving the lower urinary tract symptoms of patients with indwelling double-J ureteral stents. MATERIALS AND METHODS: A total of 168 patients underwent placement of a double-J ureteral stent after retrograde ureteroscopy for urinary stone disease. All patients received polyurethane double-J ureteral stents (6 Fr, 24 or 26 cm), which were removed a mean of 14 days postoperatively. A total of 48 patients were given no medication (Group 1), 43 patients were given tamsulosin 0.2 mg once daily (Group 2), 45 patients were given solifenacin 5 mg once daily (Group 3), and 32 patients were given a combination of two agents postoperatively (Group 4). International Prostate Symptom Score/quality of life (IPSS/QoL) and visual analogue pain scale (VAPS) questionnaires were completed by each patient at 1 day postoperatively and on the day of stent removal. RESULTS: In the total group of patients, the mean age was 50.24+/-12.90 years. There was a significant difference in the IPSS total score between group 1 and groups 3 and 4. Group 4 also differed significantly from group 1 in the irritative subscore. The obstructive subscore differed between groups 2 and 4 and group 1. There was a statistically significant difference between group 1 and group 4 in the QoL score. There were no significant differences in the VAPS. CONCLUSIONS: Combination therapy with tamsulosin and solifenacin improved both irritative and obstructive symptoms more than in the other groups. Combination therapy should be strongly considered for patients who complain of stent-related symptoms.
