Finasteride is a medication used for the treatment of conditions related to hormones, particularly in men. It is available under various brand names, including Proscar and Propecia. The uses of finasteride can differ depending on the dosage and the specific condition being treated. Mechanism of Action: Finasteride is a type II 5/alpha reductase inhibitor. It works by blocking the conversion of testosterone to dihydrotestosterone (DHT), a hormone that plays a role in the growth of the prostate gland and the miniaturization of hair follicles in male pattern baldness. Dosage and Uses: Proscar: At a higher dosage, finasteride is sold as Proscar and is used to treat benign prostatic hyperplasia (BPH), a condition in which the prostate gland enlarges and can cause urinary symptoms. Propecia: At a lower dosage, finasteride is sold as Propecia and is used to treat male pattern baldness (androgenetic alopecia) in men with mild to moderate hair loss on the vertex and anterior mid/scalp area.
