Objective: To compare the efficacy of two α 1 ‐adrenoceptor antagonists, α 1D ‐adrenoceptor‐selective naftopidil (Naf) 75 mg and α 1A ‐adrenoceptor‐selective tamsulosin hydrochloride (Tam) 0.2 mg, for the treatment of lower urinary tract symptoms (LUTS) in men with benign prostatic hyperplasia (BPH). Methods: Seventy‐seven patients with LUTS secondary to BPH were enrolled. Data were gathered from patients retrospectively: 41 patients who were prescribed Naf 75 mg for 4 weeks and 36 patients who were prescribed Tam 0.2 mg for 4 weeks, respectively. The efficacy criteria were improvement in LUTS International Prostate Symptom Score (IPSS) and quality of life (QOL) scores after dosing. Results: Naf 75 mg significantly improved symptoms in all 11 categories (overall IPSS, incomplete emptying, voiding symptoms [Intermittency, poor flow and straining], storage symptoms [daytime frequency, urgency and nocturia frequency], QOL index, intermittency, poor flow, straining, daytime frequency, urgency, and nocturia frequency) (P < 0.05). Tam 0.2 mg significantly suppressed 10 of the 11 tested symptom categories except straining (P < 0.05). Comparison data of the two drugs tended to show Naf 75 mg had better efficacy on nocturia frequency than Tam 0.2 mg (P < 0.05). Conclusion: Naf 75 mg might show a better efficacy for LUTS with BPH in nocturia frequency than Tam 0.2 mg.
