[Clinical effects of allylestrenol on patients with benign prostatic hyperplasia (BPH) evaluated with criteria for treatment efficacy in BPH].

Abstract

One hundred and twenty-nine patients with benign prostatic hypertrophy (BPH) were registered and treated with allylestrenol. Allylestrenol was administered at a dose of 50 mg/day given twice a day for 16 weeks. Out of 129 patients with a mean age of 67.8 years old, 92 cases completed the study and 48 cases with moderate symptoms were objectively evaluated with "Criteria for Treatment Efficacy in BPH" proposed by The Japanese Urological Association in 1997. Prostate volume was significantly decreased from 32.7 +/- 11.9 to 27.4 +/- 11.2 ml (mean +/- SD), and maximum flow rate was significantly increased from 8.4 +/- 3.4 to 10.8 +/- 5.0 ml/sec. Residual urine volume was significantly decreased from 62.4 +/- 57.4 to 37.0 +/- 38.7 ml. IPSS was significantly decreased from 15.3 +/- 4.9 to 9.9 +/- 4.0, and QOL index was significantly decreased from 4.4 +/- 0.8 to 2.7 +/- 1.2. The efficacy of allylestrenol was shown by its effects on prostate volume (anatomy), maximum urinary flow rate (function), and symptom scores (symptom) at the end of 16 weeks of treatment. The rates of improvement for symptoms, QOL, function, and anatomy are 68.7% (N = 48), 79.2% (N = 48), 50.0% (N = 48), and 61.0% (N = 41), respectively. Overall efficacy (Good and Fair) was 70.9% (N = 48). During this study, 5 patients (3.9%) complained of loss of libido and 2 patients dropped out. In conclusion, allylestrenol was demonstrated to be a quite effective and safe medical treatment for patients with symptomatic BPH based on the criteria for treatment efficacy in BPH.
