Abstract

We evaluated the clinical efficacy and safety of the coadministration of a PDE5 inhibitor and an α-adrenergic blocker in patients with both benign prostatic hyperplasia/lower urinary tract symptoms (BPH-LUTS) and ED using mirodenafil 50 mg (Mvixx) once daily (OD) in patients already receiving stable α-blocker therapy. This study was a prospective, multicenter, open-label trial. We selected 147 patients undergoing stable (longer than 4 weeks) α-blocker therapy for BPH-LUTS as recipients of the additive mirodenafil 50 mg OD for 8 weeks. The coprimary measures were the International Prostate Symptom Score (IPSS) and the International Index of Erectile Function (IIEF-5). The key secondary measures were peak flow rate (Q max) and postvoiding residual (PVR) volume. Safety was assessed by evaluating cardiovascular parameters and the participant-reported treatment-emergent adverse events (TEAEs). The additional administration of mirodenafil 50 mg OD significantly improved IPSS results (18.70-14.30 at 4 weeks and 18.70-13.72 at 8 weeks; P<0.001). The IIEF-5 score was improved at 8 weeks (10.94-16.16; P<0.001). There was no significant change in systolic blood pressure/diastolic blood pressure (124.8 mm Hg/78.6 mm Hg-122.0 mm Hg/79.6 mm Hg; P=0.638) and heart rates (78.8 per min to 80.2 per min; P=0.452). The most common TEAEs were hot flashes (10.9%) and headache (8.1%). The combination of mirodenafil with an α-blocker did not significantly improve PVR; however, Q max was improved at 8 weeks (14.51-16.80 ml s-1; P=0.026). Mirodenafil 50 mg OD in combination with an α-blocker appeared to have few adverse effects, to improve BPH-LUTS and restore sexual function.
