Chemical structure and physical properties of Finasteride

Finasteride is a medication that is primarily used to treat enlarged prostate (benign prostatic hyperplasia) and male pattern baldness (androgenetic alopecia). It works by inhibiting the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT), a hormone that contributes to the growth of the prostate and the shrinking of hair follicles in individuals with male pattern baldness. Here is some information about the chemical structure and physical properties of Finasteride:
