A nonsteroidal antiandrogen ( NSAA ) is an antiandrogen with a nonsteroidal chemical structure . [1] [2] They are typically selective and full or silent antagonists of the androgen receptor (AR) and act by directly blocking the effects of androgens like testosterone and dihydrotestosterone (DHT). [1] [2] NSAAs are used in the treatment of androgen-dependent conditions in men and women. [1] They are the converse of steroidal antiandrogens (SAAs), which are antiandrogens that are steroids and are structurally related to testosterone. [1] [2]
