Cyproterone acetate (CPA), sold alone under the brand name Androcur or with ethinylestradiol under the brand names Diane or Diane-35 among others, is an antiandrogen and progestin medication used in the treatment of androgen-dependent conditions such as acne, excessive body hair growth, early puberty, and prostate cancer, as a component of feminizing hormone therapy for transgender individuals ...
The side effects of cyproterone acetate (CPA), a steroidal antiandrogen and progestin, including its frequent and rare side effects, have been studied and characterized.It is generally well-tolerated and has a mild side-effect profile, regardless of dosage, when it used as a progestin or antiandrogen in combination with an estrogen such as ethinylestradiol or estradiol valerate in women.
The pharmacology of cyproterone acetate (CPA) concerns the pharmacology (pharmacodynamics, pharmacokinetics, and routes of administration) of the steroidal antiandrogen and progestin medication cyproterone acetate. CPA blocks the effects of androgens like testosterone in the body, which it does by preventing them from interacting with their ...
[4] [19] Both EE and CPA have antigonadotropic effects and act as contraceptives in women by suppressing ovulation. [17] The antigonadotropic effects of EE and CPA also contribute to the antiandrogenic efficacy of the medication by suppressing androgen production by the ovaries. [18]
Some drugs, such as medroxyprogesterone acetate, cyproterone acetate and LHRH agonists can decrease serum testosterone and estradiol in the body, thus impairing the metabolism of glucose and lipid. These drugs can also cause depression, hot flashes, infertility and anemia, aside from cardiovascular diseases and osteoporosis.

Cyproterone was studied as a treatment for precocious puberty by Bierich (1970, 1971), but no significant improvement was observed. [22] In men, 100 mg/day cyproterone proved to be rather ineffective in treating acne, which was hypothesized to be related to its progonadotropic effects in males and counteraction of its antiandrogen activity.
