Finasteride

1. Benign prostatic hyperplasia
Physicians use finasteride for the treatment of benign prostatic hyperplasia (BPH), informally known as an enlarged prostate.The FDAapproved dose is 5 mg once a day. Six months or more of treatment with finasteride may be required to determine the therapeutic results of treatment. If the drug is discontinued, any therapeutic benefits reverse within about 6 to 8 months. Finasteride may improve the symptoms associated with BPH such as difficulty urinating, getting up during the night to urinate, hesitation at the start of urination, and decreased urinary flow.

2. Male pattern baldness
Finasteride is used to treat male pattern hair loss (androgenetic alopecia) in men only. Treatment provides about 30% improvement in hair loss after six months of treatment, and effectiveness only persists as long as the drug is taken.

3. Storage and disposal of this medication

Treatment of Enlarged Prostate Gland

Finasteride (Proscar) is a very potent type II 5a-reductase inhibitor, which prevents conversion of testosterone to dihydrotestosterone (DHT). DHT is a sex hormone. In addition, it is used for treatment of benign prostatic hyperplasia (BPH), which is the enlargement of the prostate.

Finasteride inhibits 4a-reductase, and as mentioned, will prevent testosterone conversion to DHT. Studies have shown it will reduce serum DHT levels by about 65-70%, and prostate DHT levels, by up to 90%. By blocking DHT production, finasteride reduces androgen activity on the scalp; and in the prostate reduces prostate volume, which improves BPH, and reduces risk of prostate cancer.
