In healthy males, testosterone is produced primarily by the testes and in small amounts by the adrenal glands. Most of the testosterone is transported bound to a specific plasma protein called sex hormone binding globulin (SHBG). This protein is produced in the liver and carries the sex hormones (androgens in males and estrogens in females) to their site of action in the body. The testosterone that does not bind to SHBG is termed free testosterone and it is this testosterone that can be converted to dihydrotestosterone (DHT) by the enzyme 5-alpha reductase. Both DHT and testosterone can bind to the androgen receptor but DHT binds with a greater affinity than unbound or unchanged testosterone. Once bound to the androgen receptor, DHT or testosterone forms a complex that undergoes a structural change. This complex then moves into the nucleus of the cell and binds to specific nucleotide sequences of DNA called hormone response elements. Finasteride is used to shrink an enlarged prostate (benign prostatic hyperplasia or BPH) in adult men. It may be used alone or taken in combination with other medications to reduce symptoms of BPH and may also reduce the need for surgery. Finasteride may improve symptoms of BPH and provide benefits such as decreased urge to urinate, better urine flow with less straining, less of a feeling that the bladder is not completely emptied, and decreased nighttime urination. This medication works by decreasing the amount of a natural body hormone (DHT) that causes growth of the prostate. Finasteride is not approved for prevention of prostate cancer. Read the Patient Information Leaflet provided by your pharmacist before you start taking finasteride and each time you get a refill. It may slightly increase the risk of developing a very serious form of prostate cancer. If you have any questions regarding the information, consult your doctor or pharmacist. Take this medication by mouth, with or without food, usually once a day, or as directed by your doctor.

MECHANISM OF ACTION. Finasteride is a synthetic 4-aza analog of testosterone that acts as a competitive, specific inhibitor of type II 5-alpha-reductase, an intracellular enzyme that converts testosterone to the potent androgen 5-alpha-dihydrotestosterone DHT. Propecia - Clinical Pharmacology Mechanism of Action. Finasteride is a competitive and specific inhibitor of Type II 5α-reductase, an intracellular enzyme that converts the androgen testosterone into DHT. Two distinct isozymes are found in mice, rats, monkeys, and humans Type I and II. Each tablet of 'Propecia' contains 1 mg of finasteride as the active ingredient. Excipients with known effect: Each tablet contains 110.4 mg of lactose monohydrate. This medicinal product contains less than 1 mmol of sodium per tablet. 'Propecia' is indicated for the treatment of men with male pattern hair loss (androgenetic alopecia) to increase hair growth and prevent further hair loss. 'Propecia' is not indicated for use in women or children and adolescents. Posology The recommended dosage is one 1 mg tablet daily. There is no evidence that an increase in dosage will result in increased efficacy. Efficacy and duration of treatment should continuously be assessed by the treating physician. Generally, three to six months of once daily treatment are required before evidence of stabilisation of hair loss can be expected. If treatment is stopped, the beneficial effects begin to reverse by six months and return to baseline by 9 to 12 months. To DHT is regulated by the enzyme 5-alpha reductase. Finasteride (Propecia® and others) is a specific type II 5-alpha reductase inhibitor. That is, it inhibits the enzyme responsible for regulating conversion of growth. Finasteride inhibits expression of the enzyme, 5-alpha reductase, which regulates production of dihydrotestosterone (DHT). By lowering DHT levels in the scalp, it reduces DHT's harmful effect on . Finasteride decreases DHT concentrations in the serum and the scalp by up to 70 and 60%, respectively. Finasteride is an oral pill to be taken once a day.
