Mechanism of Action1-3
Finasteride is an 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. The type II 5-alpha-reductase isozyme is primarily found in prostate, seminal vesicles, epididymides, and hair follicles, as well as liver. Dihydrotestosterone has been shown to increase prostate growth and can lead to hair thinning. Finasteride has been shown to shrink the prostate to improve urinary flow and in scalp lowers dihydrotestosterone to slow hair loss and promote regrowth.
