5-alpha-reductase inhibitors
A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.
5-Alpha-reductase inhibitors block the action of 5-alpha-reductase, the enzyme that converts testosterone into dihydrotestosterone, which has greater affinity for androgen receptors. The activity of 5-alpha-reductase inhibitors results in increased levels of testosterone and decreased levels of dihydrotestosterone.
5-Alpha-reductase inhibitors are used to treat baldness, prostate hyperplasia and prostate cancer.
