0 Information about Propecia

Finasteride (marketed by Merck under the trademark names Proscar and Propecia, also available under several generic names) is a synthetic antiandrogen that inhibits type II 5-alpha reductase, the enzyme that converts testosterone to dihydrotestosterone (DHT). Finasteride was initially approved by the U.S. Food and Drug Administration (FDA) in 1992 under the brand name Proscar, as treatment for benign prostatic hyperplasia (BPH). In 1997, the FDA approved finasteride to treat male pattern baldness (MPB) under the brand name Propecia.
