Co-cyprindiol, a shortened form of combination of cyproterone acetate and ethinylestradiol, is a generic name of EE/CPA. [ 25 ] [ 26 ] [ 27 ] It is also known by its former developmental code names SHB 209 AB (Diane) [ 28 ] [ 21 ] [ 29 ] and SHB 209 AE (Diane-35).
Testosterone levels with 300 mg/week cyproterone acetate or 100 mg/month estradiol undecylate both by intramuscular injection in men. [139] Solid lines are average and dashed lines highest and lowest levels. Levels of testosterone decreased by 75% with cyproterone acetate and by 91% with estradiol undecylate. [139]
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 ...
Ethinylestradiol (EE) is an estrogen medication which is used widely in birth control pills in combination with progestins. [7] [8] In the past, EE was widely used for various indications such as the treatment of menopausal symptoms, gynecological disorders, and certain hormone-sensitive cancers.
Cyproterone acetate was developed to overcome this problem. It is formed by adding an acetate group to cyproterone, see figure 3. Cyproterone acetate has a dual mode of action as it competes directly with DHT for binding to AR, but also inhibits gonadotropin secretion. It thereby reduces androgen, estrogen and LH levels.
Estradiol valerate and cyproterone acetate (brand name Femilar) – introduced in Finland (only) in 1993 [3] Estradiol valerate and dienogest (brand names Qlaira, Natazia) – introduced in Europe in 2009 and the U.S. Tooltip United States in 2010 [4] Estradiol and nomegestrol acetate (brand name Zoely) – introduced in Europe in 2011 [5]
[1] [2] [3] It is a precursor of cyproterone acetate (CPA), an antiandrogen, progestin, and antigonadotropin which was introduced instead of cyproterone and is widely used as a medication. [ 1 ] [ 2 ] Cyproterone and CPA were among the first antiandrogens to be developed.
Synthetic estrogens, such as 17α-substituted estrogens like ethinylestradiol and its C3 esters and ethers mestranol, quinestrol, and ethinylestradiol sulfonate, and nonsteroidal estrogens like the stilbestrols diethylstilbestrol, hexestrol, and dienestrol, are no longer used in menopausal hormone therapy, owing to their disproportionate ...
