Active ingredient

Cyproterone acetate acts as an antiandrogen by blocking androgen receptors. It also has progestogenic activity, which exerts a negative feedback effect on hypothalamic receptors, so leading to a reduction in gonadotrophin release, and hence to diminished production of testicular androgens. Sexual drive and potency are reduced and gonadal function is inhibited.
