Androcur, known generically as cyproterone acetate, is a medication primarily used in the treatment of androgen-dependent conditions. It acts as an anti-androgen, blocking the effects of male hormones (androgens) in the body, which makes it useful in conditions like prostate cancer, certain types of acne, excessive hair growth (hirsutism), and for those undergoing feminizing hormone therapy as part of gender transition. Androcur works by inhibiting the action of androgens at their receptor sites and also reduces androgen production. This medication is available in tablet form and should be used under the guidance of a healthcare professional due to its potential side effects and the need for monitoring during treatment.
