Finasteride is an aza-steroid that is a synthetic drug for the treatment of benign prostatic hyperplasia. It has a role as an androgen antagonist, an EC 1.3.1.22 [3-oxo-5alpha-steroid 4-dehydrogenase (NADP(+))] inhibitor and an antihyperplasia drug. It is an aza-steroid, a 3-oxo steroid and a delta-lactam. It derives from a hydride of a 5alpha-androstane.|Finasteride is a synthetic 4-azasteroid compound and specific inhibitor of steroid Type II 5α-reductase, which is an intracellular enzyme that converts the androgen testosterone into 5α-dihydrotestosterone (DHT). It works in a similar fashion as [dutasteride], which is another 5-alpha-reductase inhibitor, by exerting antiandrogenic effects. Finasteride is an orally active drug that was first approved by the FDA in 1992 for the treatment of benign prostatic hyperplasia to improve symptoms and reduce the risk for acute urinary retention or the need for surgical procedures. In 1998, it was approved by the FDA to treat male pattern hair loss. Finasteride is commonly marketed under the brand names Propecia and Proscar to be used aloneo or in combination with [doxazosin], an alpha-blocker. Both benign prostatic hyperplasia and androgenic alopecia are androgen-dependent disorders that are characterized by in situ high levels of DHT. In the treatment of benign prostate hyperplasia, alpha-blockers such as [tamsulosin] and [terazosin] are also used. Compared to alpha-blockers that focus on providing the rapid relief of symptoms, 5α-reductase inhibitors aim to target the underlying disease by blocking the effects of the primary androgen involved in benign prostate hyperplasia and androgenic alopecia, thus reducing the risk for secondary complications while providing symptom control.|Finasteride is a 5-alpha Reductase Inhibitor. The mechanism of action of finasteride is as a 5-alpha Reductase Inhibitor.|Finasteride is a 5-alpha reductase inhibitor used to treat symptoms of benign prostatic hypertrophy and male pattern baldness. Finasteride is associated with a low rate of transient serum aminotransferase elevations, but has yet to be linked to instances of clinically apparent, acute liver injury.|Finasteride is a synthetic 4-azasteroid compound. Finasteride competitively binds to and inhibits steroid type II 5-alpha-reductase in the prostate gland, liver, and skin, thereby interfering with the enzymatic conversion of testosterone to 5-dihydrotestosterone (DHT) and reducing serum DHT levels. The reduction in serum DHT levels results in diminished stimulation of androgen receptors in the nuclei of prostate cells and, so, diminished prostate cell proliferation.|An orally active 3-OXO-5-ALPHA-STEROID 4-DEHYDROGENASE inhibitor. It is used as a surgical alternative for treatment of benign PROSTATIC HYPERPLASIA.
