[Therapeutic usefulness of antiandrogens].

Antiandrogens are substances that block androgen receptors. The antiandrogenic action of some of these medications, as H2 blockers and some diuretics, was discovered as a collateral effect. They are used for the treatment of acne, hirsutism and seborrhea in women; they are also used in precocious puberty and sexual hyperexcitability states. The clinical usefulness of these drugs is unquestionable, but their prescription requires a through knowledge of their endocrinological effects.
