- This is a tablet that is taken daily.
- It works by blocking the enzyme 5-alpha-reductase, which results in the suppression of the conversion of testosterone to its most potent form dihydrotestosterone.
- It has been established as safe and well-tolerated, with very few side effects.
- It is less potent than other antiandrogen medications, so it can take longer to make noticeable changes.
Mechanism
Finasteride works by inhibiting the enzyme 5-alpha-reductase, which is responsible for converting testosterone into its more potent form, dihydrotestosterone (DHT). By blocking this conversion, Finasteride reduces the levels of DHT in the body.
