Steroidal antiandrogen
Class of compounds / From Wikipedia, the free encyclopedia
A steroidal antiandrogen (SAA) is an antiandrogen with a steroidal chemical structure.[1][2][3] They are typically antagonists of the androgen receptor (AR) and act both by blocking the effects of androgens like testosterone and dihydrotestosterone (DHT) and by suppressing gonadal androgen production.[2][3] SAAs lower concentrations of testosterone through simulation of the negative feedback inhibition of the hypothalamus.[4] SAAs are used in the treatment of androgen-dependent conditions in men and women, and are also used in veterinary medicine for the same purpose.[2] They are the converse of nonsteroidal antiandrogens (NSAAs), which are antiandrogens that are not steroids and are structurally unrelated to testosterone.[2][3]
