A comparison of the efficacy of naftopidil and tamsulosin hydrochloride in medical treatment of benign prostatic enlargement

Introduction: Lower urinary tract symptoms in men, over age of 50 years is suggestive of benign prostatic enlargement (BPE). Different alpha-blockers have been evaluated for the treatment of benign prostatic hyperplasia for over last 30 years. This study was conducted in a tertiary care institution during the period of year between June 2011 and August 2013 to compare the effect of naftopidil and tamsulosin in reducing the obstructive and irritable symptoms of BPE. Subjects and Methods: A prospective randomized comparative study was carried on 60 patients of BPE by assigning half of them to treatment with tamsulosin and rest with naftopidil. Pre- and post-treatment uroflowmetry (UFM), post-void residue (PVR), International Prostate Symptoms Score (IPSS), were obtained at 15 and 30 days after starting treatment. Results: The age of patients ranged from 51 to 78. At base line there was no statistical difference between UFM parameter, PVR and IPSS in the two groups. UFM and PVR showed significantly better response at both intervals with naftopidil. Comparison of IPSS showed better improvement in Group A both at 15 and 30 days. It was seen that the obstructive symptoms showed a significantly better response with tamsulosin and symptoms of irritability was seen better response with naftopidil. Conclusion: It was seen that during the period of follow-up of 30 days naftopidil had a better effect on UFM, PVR, IPSS compared with tamsulosin. In general, obstructive symptoms showed better improvement in tamsulosin and irritative symptoms showed better improvement in naftopidil.
