Mirabegron add-on therapy to tamsulosin for the treatment of overactive bladder in men with lower urinary tract symptoms

Men with lower urinary tract symptoms (LUTS) treated with α-blockers may experience overactive bladder (OAB) symptoms and receive antimuscarinic drugs. Mirabegron (B3-adrenoreceptor agonist) is an alternative add-on therapy, that has been shown to be more effective than placebo in improving OAB symptoms. Superior results observed for tamsulosin plus mirabegron in mean volume voided per micturition, urgency episodes per day, and total urgency and frequency score. Higher rates of drug related treatment emergent adverse events were noted with tamsulosin plus mirabegron. The results of PLUS reveal the utility of mirabegron and tamsulosin therapy in the treatment of men with benign prostatic hyperplasia who developed symptoms of overactive bladder. The MATCH study confirmed that combination therapy for 12 weeks in men with symptoms of LUTS and OAB was more effective than placebo and was well tolerated.
