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 ...
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.
It was widely used, but has largely been abandoned for this indication in favor of newer agents with improved safety profiles and fewer feminizing side effects. [23] Cyproterone acetate was developed subsequently to high-dose estrogen and is the only steroidal antiandrogen that has been widely used in the treatment of prostate cancer, [24] but ...
Your body creates DHT as a byproduct of testosterone, the main androgen hormone in the male body. You need DHT to develop male features before birth and during adolescence, such as your external ...
Chemical castration is generally reversible when treatment is discontinued, [3] although permanent effects in body chemistry can sometimes be seen, as in the case of bone density loss increasing with length of use of depot medroxyprogesterone acetate (DMPA). In men, chemical castration reduces sex drive and the capacity for sexual arousal, side ...
[1] [7] Cyproterone acetate acts both directly as an antiandrogen in prostate cancer cells and also functions to indirectly decrease serum testosterone levels. The latter causes the limitations of cyproterone acetate, which are central effects on androgen secretion, with subsequent loss of libido and sexual potency.
Therefore a complementary treatment was developed that uses antiandrogens to block the body's ability to use any androgens. Prostate cells contain an Androgen Receptor (AR), that when stimulated by androgens like testosterone, promotes growth and maintains prostatic differentiation.
