Abstract

Objectives: Effect of tadalafil on lower urinary tract symptoms (LUTS), erectile function and quality of life (QoL) were prospectively evaluated in patients with benign prostatic hyperplasia (BPH) at multicenter. Methods: Eligible men were ≥40 years who had no treatment with alpha-blocker for BPH, with total International Prostate Symptom Score (IPSS) ≥8, IPSS-QOL ≥2 and prostate volume ≥20 mL. Data were collected on age, body mass index (BMI), and prostate specific antigen (PSA). Patients were asked to complete a self-reported questionnaire regarding the IPSS, Overactive Bladder Symptom Score (OABSS), International Index of Erectile Function 5 (IIEF5), and Medical Outcome Study 8-Item Short-Form Health Survey (SF-8). These measures were assessed at baseline, 4-, 8-, 12-week of tadalafil treatment. In addition, uroflowmetry was also performed at baseline, and 12-week end point visit. Results: Thirty five patients with mean age 67.3 years, mean BMI 23.6 kg/m2, mean prostate volume 36 mL, and mean PSA 3.4 ng/mL were enrolled. Treatment with tadalafil significantly improved IPSS total score, IPSS voiding subscore, IPSS storage subscore, OABSS and IPSS-QoL score after 4 weeks and these improvements were maintained for 12-week treatment period. IIEF5 score and general health in SF-8 are significantly improved with the treatment of tadalafil. However, maximum flow rate and postvoiding residual volume were not significantly changed. There were not any serious adverse events. Conclusions: These results indicate that tadalafil 5 mg once daily would be effective and well tolerated treatment in Japanese men with BPH-LUTS.
