Efficacy of Silodosin in the Treatment of Symptomatic Benign Prostatic Hyperplasia (BPH)
Efficacy of Silodosin in the Treatment of Symptomatic Benign Prostatic Hyperplasia (BPH)
In this study the investigators had evaluated the effectiveness SILODOSIN (8 mg daily orally)
 in Benign prostatic Hyperplasia in comparison to Tamsulosin (0.4 mg daily orally) in a
 randomized controlled trial design. Study population would be patients attending Urology OPD
 of BSMMU Hospital, Dhaka. Target sample size will be 136 evaluable patients in each group
 (assuming dropout rate 20%), suffering from Benign prostatic Hyperplasia .Subjects would be
 observed for 1 week without any drug. At the end of 1 week, they would be randomly allocated
 to Silodosin or Tamsulosin and treatment continued for 12 weeks. Interim follow-up visits
 would be at 1,4 and 12 weeks. USG confirmation of BPH would be required for recruitment.
 Effectiveness of the drugs would be assessed by International Prostate Symptom score, a
 quality of life (QoL) assessment done by a 7-point scale. Prostate weight/volume
 determination by USG, Change in post voidal residual urine (PVR) by USG and Changes in peak
 urine flow rate by uroflowmetry. Safety would be assessed by following up vital signs,
 treatment emergent adverse events and routine laboratory tests for drug safety.
Benign prostatic hyperplasia (BPH) is the most common cause of lower urinary tract symptoms
 in elderly men. Selective α1-adrenergic antagonists are now ﬁrst-line drugs in the medical
 management of BPH. This Hospital based randomized controlled clinical study designed to
 evaluate the efficacy of the new α1-blocker silodosin in the treatment of symptomatic benign
 prostatic hyperplasia (BPH).Ambulatory patients of age between 50 to 70 years, who were
 diagnosed as benign prostatic hyperplasia, were divided into two groups after fulfilling
 selection criteria. After informed consent & random sampling by lottery, silodosin 8 mg was
 given to group A (study) & tamsulosin 0.4 mg was given to group B (control). Total 149
 patients were enrolled in this study but 8 patients were lost during follow up. Hence 141
 patients completed the study, during the period of June 2017 to August 2018.
