The most well-known trade name for finasteride is Propecia, which is used to treat male pattern baldness. Another prominent trade name for finasteride is Proscar, prescribed for the treatment of benign prostatic hyperplasia (BPH) [1].
What is the difference between Propecia and Proscar?
While both Propecia and Proscar contain the same active ingredient, finasteride, they are prescribed for different medical conditions and dosages. Propecia is formulated for treating hair loss in men at a dosage of 1 milligram. Proscar, on the other hand, is used to treat an enlarged prostate and is typically prescribed at a dosage of 5 milligrams [2].
How does finasteride work?
Finasteride functions by inhibiting an enzyme called 5-alpha-reductase. This enzyme is responsible for converting testosterone into dihydrotestosterone (DHT). DHT is a hormone that plays a significant role in the development of male secondary sexual characteristics and also contributes to hair loss and the enlargement of the prostate gland. By reducing DHT levels, finasteride can help slow down hair loss and shrink the prostate [3].
When does finasteride patent exclusivity expire?

Are there generic versions of finasteride available?
Yes, generic versions of finasteride are available, particularly for its use in treating BPH. The availability of generic finasteride has contributed to lower costs for the medication [5].
What are the potential side effects of finasteride?
As with any medication, finasteride can cause side effects. Some commonly reported side effects include decreased libido, erectile dysfunction, and ejaculation disorders.
