The Relative Efficacy and Safety of Mirabegron and OnabotulinumtoxinA in Patients With Overactive Bladder who Have Previously Been Managed With an Antimuscarinic: A Network Meta-analysis.

ABSTRACT

OBJECTIVE: To compare the efficacy and safety of mirabegron and onabotulinumtoxinA in the management of treatment-experienced patients with overactive bladder. METHODS: The network meta-analysis was based on evidence from a systematic literature review of randomized controlled trials and a post-hoc analysis of treatment-experienced subpopulations from mirabegron studies. RESULTS: Nineteen trials described in 21 publications were included. CONCLUSION: Overall, compared to mirabegron, there was some evidence that onabotulinumtoxinA was associated with improved outcomes, including reductions in the number of micturitions in a 24-hour period, and the number of incontinence episodes. However, mirabegron was associated with a lower risk of urinary tract infections compared with onabotulinumtoxinA.
