GlossaryAndrogen Receptor Antagonists (AR antagonists)

block male hormones like testosterone from affecting tissues

Androgen Receptor Antagonists, also known as antiandrogens, are medications that block the action of androgens, which are male sex hormones like testosterone. These drugs work by binding to androgen receptors, preventing androgens from exerting their effects on tissues, and are commonly used in the treatment of conditions like prostate cancer, androgenic alopecia (male-pattern baldness), and certain types of acne.
