Brief Summary:
Hypothesis: Dutasteride will perform better than finasteride in decreasing prostate volume, improving symptoms based on International Prostate Symptom score,and lower pvr based on the scientific information that dutasteride inhibits both Type I and II 5-alpha-reducatase vs. finasteride which only inhibits the Type II enzyme

Condition or disease Intervention/treatment Phase
Benign Prostatic Hyperplasia Drug: Dutasteride Phase 4
