tolterodine-tartrate and Hypertension

Mirabegron, a β3-adrenoceptor agonist, was approved for overactive bladder (OAB), but worsened hypertension was a potential risk based on its mechanism of action. Besides, head to head comparisons were limited between mirabegron and antimuscarinic agents, the prior first-line pharmacotherapy of OAB. In this regard, we performed a systematic review and meta-analysis to compare their efficacy as well as safety, especially in blood pressure changes.. Literature search was conducted in PubMed, Medline and seven randomized clinical trial (RCT) register databases of WHO, EU, USA, Taiwan, China, Japan and Cochrane. Completed RCTs for OAB with mirabegron and antimuscarinics were identified and the last comprehensive search was run in August 2017. Cochrane risk of bias tool was used to assess the potential bias, and RevMan5 software was performed for meta-analysis.. Seven eligible RCTs (four for mirabegron vs. tolterodine and three for mirabegron vs. solifenacin) were included and demonstrated similar efficacy in micturitions, incontinence, and nocturia between mirabegron and antimuscarinics. In hypertension issue, no statistical differences were showed in risk ratio (RR) of hypertension events, change of blood pressure from baseline and change of blood pressure from placebo for all participants. On the other hand, RR of dry mouth was significantly lower in mirabegron users.. Mirabegron was not inferior effective in improving OAB symptoms compared with antimuscarinic agents. In addition, mirabegron presented lower incidence of dry mouth and not higher risk for hypertension. Therefore, mirabegron has potential to be an alternative therapeutic option for OAB control.

The aim of the present review article was to summarize the efficacy and tolerability for mirabegron 50 mg over 12 weeks and 1 year versus placebo (SCORPIO) or tolterodine ER 4 mg (SCORPIO and TAURUS). After a 2-week placebo run-in, adults with overactive bladder symptoms for ≥3 months were randomized if, during a 3-day micturition diary period before baseline, they had an average of ≥8 micturitions/24 h and ≥3 urgency episodes. Efficacy end-points were change from baseline to each study visit and final visit in incontinence, micturitions, volume voided/micturition, urgency incontinence, urgency (grades 3 or 4), level of urgency and nocturia. Additional secondary efficacy variables included patient-reported outcomes. Safety variables included changes in treatment-emergent adverse events and vital signs. For SCORPIO, statistically significant improvements from baseline in efficacy variables and patient-reported outcomes were seen with mirabegron versus placebo from week 4, and were maintained over time. For TAURUS, numerical improvements in efficacy were evident from month 1, and were maintained throughout 12 months. Treatment-emergent adverse events incidence was similar between groups, except for dry mouth, which was reported by fourfold (SCORPIO) and threefold (TAURUS) more patients taking tolterodine than mirabegron. Mirabegron 50 mg for 12 weeks was associated with statistically significant improvements in objective measures of efficacy and patient-reported outcomes. At final visit, improvements with mirabegron 50 mg were statistically greater versus placebo. The efficacy profile of mirabegron 50 mg appears to be maintained over 12 months.

Despite several antimuscarinic treatment options for overactive bladder (OAB), there is still a need for distinct treatment approaches to manage this condition. Mirabegron, a β(3)-adrenoceptor agonist, has demonstrated efficacy and tolerability for up to 12 wk in phase 3 trials.. To assess the 12-mo safety and efficacy of mirabegron.. Patients ≥ 18 yr of age with OAB symptoms for ≥ 3 mo.. After a 2-wk single-blind placebo run-in, patients with eight or more micturitions per 24h and three or more urgency episodes in a 3-d micturition diary were randomized 1:1:1 to once-daily mirabegron 50mg, mirabegron 100mg, or tolterodine extended release (ER) 4 mg for 12 mo.. Primary variable: incidence and severity of treatment-emergent AEs (TEAEs). Secondary variables: change from baseline at months 1, 3, 6, 9, and 12 in key OAB symptoms.. A total of 812, 820, and 812 patients received mirabegron 50mg, mirabegron 100mg, and tolterodine ER 4 mg, respectively. Baseline demographic and OAB characteristics were similar across groups. TEAEs were reported in 59.7%, 61.3%, and 62.6% of patients, respectively; most were mild or moderate. Serious TEAEs were reported in 5.2%, 6.2%, and 5.4% of patients, respectively. The most common TEAEs were similar across groups. Dry mouth was reported by 2.8%, 2.3%, and 8.6% of patients, respectively. Adjusted mean changes from baseline to final visit in morning systolic blood pressure were 0.2, 0.4, and -0.5mm Hg for mirabegron 50mg, 100mg, and tolterodine ER 4 mg, respectively. Mirabegron and the active control, tolterodine, improved key OAB symptoms from the first measured time point of 4 wk, and efficacy was maintained throughout the 12-mo treatment period. The study was not placebo controlled, which was a limitation.. The safety and tolerability of mirabegron was established over 1 yr, with sustained efficacy observed over this treatment period.. ClinicalTrials.gov identifier: NCT00688688.

Antimuscarinic (AM) and beta-3-agonist (B3A) treatment are the standard first-line pharmacological treatment used to manage overactive bladder (OAB) patients. Aim of our study was to analyze real-life data of adverse events related to AMs and B3A reported on Eudra-Vigilance (EV) Database.. EV database is the system for managing and analyzing information on suspected adverse reactions to medicines which have been authorized or being studied in clinical trials in the European Economic Area (EEA). We recorded the number of AEs for antimuscarinic and beta-3-agonist per category and severity until January 2021.. Overall, 2313 AEs were reported for oxybutinin, 5129 for solifenacin, 2483 for tolterodine, 3523 for fesoterodine, 787 for trospium, 621 for propiverine and 7213 for mirabegron. Urinary retention was higher for fesoterodine (43%) and tolterodine (23%) when compared to solifenacin (10%), mirabegron (11%) and oxybutinin (4%). Cognitive disorder was uncommon for all the analyzed drugs analyzed. Regarding anticolinergic AEs: vision blurred, dry mouth and constipation were higher for AMs when compared to mirabegron. Their prevalence was higher in female patients. Mirabegron presented a higher risk of hypertension (7%) when compared to oxybutinin (2%, P<0.01), solifenacin (2%, P<0.01), tolterodine (2%, P<0.01) and fesoterodine (1%, P<0.01); the rate of hypertension was higher in females (63%) than males (29%) (P<0.01). The risk of acute urinary retention was also significantly higher (15% vs. 10%, P<0.01) in older patients (>85 years).. Real life data is consistent with registry studies regarding the rate of AEs related to antimuscarinic and beta-3-agonist. However some differences were observed. Female patients present higher rates of AEs when compared to male patients. The risk of acute urinary retention was particularly evident in the octogenarians.
