Neurological safety and efficacy of darifenacin and mirabegron for the treatment of overactive bladder in patients with history of cerebrovascular accident: A prospective study.

To evaluate the neurological safety and clinical efficacy of darifenacin and mirabegron in patients with a history of cerebrovascular accident (CVA) who had overactive bladder (OAB) symptoms.

This prospective randomized study, approved by the institute's ethics committee, was carried out at a tertiary care center from December 2018 to June 2020. Treatment naïve adult patients with a past history of CVA with stable neurological status for atleast past 3 months with symptoms of OAB for 3 or more months were included. Eligible patients received either darifenacin or mirabegron for a period of 3 months and various parameters on the 3-day International Consultation on Incontinence Questionnaire (ICIQ) bladder diary, the Montreal Cognitive Assessment-Basic score (MoCA-B), and the adverse events at 3 months posttreatment were compared to that at the baseline.

A total of 60 patients were included, 30 in each arm. After 3 months of treatment with darifenacin or mirabegron, the majority of the ICIQ bladder diary parameters improved and there was no deterioration in the cognitive function as noted on the MoCA-B score in either of the arms. On intergroup comparison, the mean change in bladder diary parameters and the MoCA-B scores was similar between the two groups.

Darifenacin and mirabegron, in the short term, do not adversely affect the cognitive function in patients with a history of CVA with OAB symptoms. Both are safe and effective treatment options in patients with OAB post-CVA.
