Primary Outcome Measures:

Adverse Events [ Time Frame: 9 months ]
All reported adverse events were recorded. Clinically significant abnormal laboratory values or other clinical findings upon examination were also recorded as adverse events.

Secondary Outcome Measures:

International Prostate Symptom Score (IPSS) [ Time Frame: 9 months ]
The IPSS is a symptom severity scale from 0 to 35 that is derived from a 7 item questionnaire. 0 indicates no symptoms and 35 indicates most severe symptoms.


Enrollment:	661

Study Completion Date:	April 2007
Primary Completion Date:	April 2007 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: Silodosin Silodosin 8 mg per day with food	Drug: Silodosin 8 mg daily Other Name: Rapaflo

Detailed Description:

This will be a multi-center, open-label 40 week investigation in up to 1,200 men with signs and symptoms of benign prostatic hyperplasia. The following procedures are utilized: physical exams, electrocardiograms, clinical laboratory tests, vital signs, the International Prostate Symptom Score, maximum urine flow rate, adverse events, concomitant medications, and compliance.

All subjects had previously participated in a 12-week double-blind placebo controlled trial (NCT000224107 or NCT000224120)
