Finasteride is a drug that belongs to the class of androgen inhibitors, which means that it blocks the production of male sex hormones. It is sold in the United States and Canada under the brand names Proscar and Propecia.
By Dr Ananya Mandal, MD. Finasteride is an anti-androgen agent that is used to treat benign prostatic hyperplasia (prostate enlargement) and male pattern baldness. Finasteride works by inhibiting the type II 5-alpha reductase enzyme, which converts testosterone into its more potent form, dihydrotestosterone (DHT).n 1997, finasteride (1 mg) per day was also approved by the FDA as a treatment for male pattern baldness and this time the agent was marketed by Merck as Propecia.
