Proscar (Finasteride) is a type of steroid reductase inhibitor. It works by reducing the amount of the hormone dihydrotestosterone (DHT) in the body. This makes the prostate gland smaller, which helps to relieve urinary problems. Proscar is an effective treatment by Merck & Co. against urinary problems caused by BPH.
Proscar also marketed as: Anatine, Finasteride, Nasterid, Propecia, Prosmin.
