Used primarily in the treatment of prostate cancer, this compound acts as an anti-androgen by blocking the effects of androgens like testosterone in the body. It is often prescribed in combination with a gonadotropin-releasing hormone (GnRH) agonist to enhance therapeutic effectiveness. The drug helps slow the growth of prostate tumors that depend on androgens for progression. It may also be used in certain cases of hirsutism and other androgen-dependent conditions in women, though this is less common. Due to potential liver toxicity, regular monitoring of liver function is required during treatment.
