A substance that keeps androgens (male hormones) from binding to proteins called androgen receptors, which can be found in prostate cells and cells of some other tissues. Treatment with antiandrogens may stop prostate cancer cells from growing. Examples of antiandrogens used to treat prostate cancer are flutamide, bicalutamide, enzalutamide, and nilutamide.
