Dutasteride is a medication primarily prescribed for the management of benign prostatic hyperplasia (BPH), also known as an enlarged prostate, and for male pattern hair loss (androgenetic alopecia). It belongs to a class of drugs called 5-alpha-reductase inhibitors. Its action involves reducing the levels of dihydrotestosterone (DHT), a potent androgen hormone that plays a key role in the development of BPH and hair loss. Dutasteride is available in oral capsule form and is often marketed under the brand name Avodart. It is typically used long-term due to its mechanism of action and the chronic nature of the conditions it treats. The dose is user-directed and must be set by a licensed clinician.
