Finasteride is a medication primarily used to treat benign prostatic hyperplasia (BPH) and male pattern baldness. Its active ingredient is finasteride itself [1].
What does finasteride do in the body?
Finasteride works by inhibiting the enzyme 5-alpha-reductase, which is responsible for converting testosterone into dihydrotestosterone (DHT) [1]. DHT is a more potent form of testosterone that plays a significant role in the growth of the prostate gland and hair follicles. By reducing DHT levels, finasteride can shrink an enlarged prostate and slow or reverse hair loss in men [1].
What are the different strengths of finasteride available?
Finasteride is typically available in two strengths: 1 mg for hair loss and 5 mg for prostate enlargement [2].
How does finasteride for hair loss differ from finasteride for prostate issues?
The primary difference is the dosage. The 1 mg dose is formulated for treating male pattern baldness, while the 5 mg dose is prescribed for managing symptoms of benign prostatic hyperplasia (BPH) [2]. Both formulations contain the same active ingredient, finasteride, but at different concentrations.
Are there different types of finasteride medications?
Finasteride is available as a generic medication and also under brand names. For BPH, the brand name Proscar is well-known, and for male pattern baldness, Propecia is the common brand name [2]. These brand names may have different excipients or inactive ingredients, but the active pharmaceutical ingredient remains finasteride.
What are the side effects of finasteride?
Potential side effects of finasteride can include sexual side effects such as decreased libido, erectile dysfunction, and ejaculation disorders. Some men may also experience breast tenderness or enlargement. In rare cases, more serious side effects have been reported [3].
Can finasteride be used by women?
Finasteride is generally not recommended for use by women, particularly those who are or may become pregnant, due to the risk of birth defects in male infants [3].
What is the patent status of finasteride?
The original patents for finasteride have expired, allowing for the production of generic versions of the drug. DrugPatentWatch.com provides information on drug patents, including those for finasteride [4].
