Comparison of Naftopidil 75 mg with Tamsulosin Hydrochloride 0.2 mg in the Treatment of Lower Urinary Tract Symptoms with Benign Prostatic Hyperplasia
LUTS: Lower Urinary Tract Symptoms, 04/02/2012
Naftopidil 75 mg might show a better efficacy for lower urinary tract symptoms with benign prostatic hyperplasia in nocturia frequency than Tam 0.2 mg.
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.
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).
