mirabegron and Hypertension

We conducted this meta-analysis to explore the tolerance of monotherapy with mirabegron (50 mg) on an overactive bladder, compared with a common dosage of anticholinergic agents.. A comprehensive search for all randomized controlled trials that evaluated the safety of mirabegron and anticholinergic agents on overactive bladder was performed, and we searched the Cochrane Central Register of Controlled trials databases, Pubmed, Embase, and relevant trials from 2013.02 to 2019.10.. Eight studies included 5500 patients with treatment of monotherapy on overactive bladder were identified. The total number of treatment-emergent adverse events had no significantly difference between two monotherapies (RR = 0.88 95%CI: 0.76-1.01; P = .08); however, patients would have a better tolerance with mirabegron (50 mg) in adverse events of dry mouth (RR = 0.42; 95%CI: 0.33-0.53; P < .01) and tachycardia (RR = 0.52; 95%CI: 0.29-0.94; P = .03); and there were no significant differences between two groups in hypertension (RR = 1.02; 95%CI: 0.80-1.30; P = .90), constipation (RR = 0.91; 95%CI: 0.65-1.26; P = 0.57), blurred vision (RR = 1.03; 95%CI: 0.60-1.77; P = 0.92), and urinary tract infection (RR = 0.90; 95%CI: 0.70-1.16; P = .41).. Treatment-emergent adverse events in patients with overactive bladder who underwent monotherapy of mirabegron (50 mg) or the anticholinergic agents had no significant differences, but mirabegron has a better tolerance in the aspect of dry mouth and tachycardia.

Overactive bladder (OAB) syndrome is common in the general population, particularly in elderly patients. Antimuscarinic drugs (AMs) are considered the mainstay pharmaceutical treatment of OAB whereas β3-adrenoceptor agonists, such as mirabegron, represent a good alternative. Owing to the important role of muscarinic and β3 receptors in cardiovascular (CV) tissue and to the fact that OAB patients often have CV comorbidities, the safety-profile of these drugs constitute an important challenge.. The aim of this review is to evaluate the CV effects of AMs and mirabegron in OAB. A systematic literature search from inception until December 2017 was performed on PubMed and Medline.. AMs are generally considered to have good CV safety profile but, however, they may cause undesirable adverse events, such as dry mouth, constipation. CV AEs are rare but noteworthy, the most common CV consequences related to the use of these drugs are constituted by an increase in HR and QT interval. Mirabegron has similar efficacy and tolerability to AMs but causes less adverse events, with either modest hypertension and modest increase in HR (<5 bpm) being the most commonly reported.

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.

To assess the efficacy and tolerability of mirabegron 25 mg and 50 mg once-daily vs placebo in patients with overactive bladder (OAB).. Patients ≥18 years with OAB symptoms were recruited to a 2-week, single-blind, placebo run-in. Those with ≥8 micturitions per 24 hours and ≥3 urgency episodes were randomized 1:1:1 to once-daily mirabegron 25 mg or 50 mg, or placebo for 12 weeks. Primary endpoints were changes to final visit in mean number of incontinence episodes and micturitions per 24 hours. Key secondary endpoints were changes to final visit in mean volume voided or micturition, change to week 4 in mean number of incontinence episodes and micturitions per 24 hours, changes to final visit in mean level of urgency, number of urgency incontinence episodes, and urgency (grade 3 or 4) episodes per 24 hours. Patient-reported outcomes were assessed using the OAB-questionnaire, Patient Perception of Bladder Condition, and Treatment-Satisfaction-Visual Analog Scale.. Both mirabegron groups demonstrated statistically significant improvements in coprimary endpoints vs placebo. Mirabegron 50 mg demonstrated significantly greater improvements vs placebo in the following: change to final visit in mean volume voided per micturition and change to week 4 in mean number of incontinence episodes per 24 hours. Statistically significant improvements vs placebo were demonstrated by mirabegron 50 mg in all patient-reported outcome scales with no increase in the incidence of treatment-emergent adverse events vs placebo.. Mirabegron 25 mg and 50 mg were associated with significant improvements in efficacy measures of incontinence episodes and micturition frequency. Mirabegron was well tolerated vs placebo.

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.

Mirabegron is a relatively new drug to treat overactive bladder (OAB). The therapeutic doses are between 25 and 100 mg in clinical trials. We aimed to evaluate the efficacy and persistence of low-dose mirabegron (25 mg) in patients with OAB in daily urological practice.. The study was a retrospective consecutive cohort of 177 OAB patients (101 male and 76 female) treated with 25 mg of mirabegron mg since January 2016 to November 2016. The therapeutic outcomes were assessed at baseline, 4, 12, and 24 weeks.. Mirabegron usage was associated with a statistically significant decrease in Overactive Bladder Symptom Score, Urgency Severity Score, urge urinary incontinence, International Prostate Symptom Score (both storage and voiding symptom) at 4-week follow-up, and the therapeutic effects were further improved at 12- and 24-week follow-up. Among them, 118 patients (66.7%) and 84 patients (47.5%) were maintained on mirabegron therapy for more than 3 and 6 months, respectively. However, 29 patients (16%) had poor response with drug discontinuation within 3 months and 8 patients (4.5%) stopped medication due to adverse effects. The overall side effect was 10.2%, and the most common side effect was elevated blood pressure (2.8%) and increased post-void residual (2.8%). Between male and female patients, there was no statistical difference of symptom improvement and drug persistence rate.. Low-dose mirabegron (25 mg) improves clinical outcomes in two-thirds of OAB patients with good safety profile and high persistence in daily urological practice. The therapeutic effect is similar between the genders.

To provide real-world data on Japanese patients with overactive bladder (OAB) initiating treatment with the β. Full medical histories, including prior/concomitant drug use, were collected before initiating mirabegron treatment. After 12 weeks mirabegron, physicians assessed ADR incidence and treatment effectiveness. Residual urine volume was assessed and patients completed the Overactive Bladder Symptom Score (OABSS) and International Prostate Symptom Score-Quality of Life (I-PSS QoL) surveys at Baseline and 12 weeks. Data were collected between April 2012 and July 2014.. Of 9795 OAB patients (46.8% male; 80.8% ≥65 years), 71.7% had coexisting disease [notably benign prostatic hyperplasia (BPH, 32.4%), hypertension (31.9%), and diabetes mellitus (9.4%)] and 53.4% reported concomitant drug use (27.8% α. In the clinical setting, mirabegron is well tolerated, with no unanticipated ADRs, and is an effective treatment for Japanese patients with OAB.

Antimuscarinic medications have long been the mainstay of drug treatment for overactive bladder. This article describes mirabegron, one of a new class of agents that relaxes the detrusor muscle directly via a beta3 adrenoceptor agonist. Mirabegron's efficacy on frequency, urgency, and urge incontinence was tested in several trials before its wide clinical introduction. However, caution is still needed as data are lacking on the drug's efficacy and safety in frail older adults and for long-term therapy.
