The purpose of this study was to look at the efficacy and safety of mirabegron in males with overactive bladder (OAB) and benign prostatic hyperplasia (BPH) (BPH). Mirabegron has been demonstrated in several trials to be effective and safe in the treatment of OAB symptoms. More recent trials investigating the use of mirabegron in males with OAB and BPH have also demonstrated that the drug is beneficial with little adverse side effects when taken alone or in combination treatment.Mirabegron is a safe and efficient therapy for men with OAB and BPH.
