Abstract:
We studied the efficacy of naftopidil (50 mg/day) on nocturia associated with benign prostatic hyperplasia in 35 patients (62-80 years old). The patients had BPH > 20 ml, nocturia, more than 3 times, international prostate symptom score (IPSS) > 7, quality of life score (QOL) < 1, and maximum flow rate (Qmax) < 15 ml/sec. They received naftopidil for more than 6 weeks. IPSS, QOL, Qmax, micturition volume, and side effects were analyzed. Naftopidil was effective for nocturia associated with benign prostatic hyperplasia, especially when taken at night.
