Need a prescription!: Finasteride (brand names Proscar and Propecia (finasteride) by merck, among other generic names) is a synthetic type ii 5?-reductase inhibitor. This enzyme converts testosterone to dihydrotestosterone (dht). Finasteride is approved for the treatment of benign prostatic hyperplasia (BPH) and male pattern baldness (mpb).
