Chlormadinone acetate (CMA), sold under the brand names Belara, Gynorelle, Lutéran, and Prostal among others, is a progestin and antiandrogen medication which is used in birth control pills to prevent pregnancy, as a component of menopausal hormone therapy, in the treatment of gynecological disorders, and in the treatment of androgen-dependent conditions like enlarged prostate and prostate ...
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 ...
[1] [2] An acylated derivative, chlormadinone acetate, is used clinically as a pharmaceutical drug. [1] [2] It was patented in 1958 and approved for medical use in 1963. [3] While chlormadinone is sometimes used as a synonym for chlormadinone acetate, what is almost always being referred to is chlormadinone acetate and not chlormadinone.
Testosterone levels with 100 to 300 mg/day oral cyproterone acetate and low-dose oral estrogen in men. [160] The estrogen used was 0.1 mg/day diethylstilbestrol (DES), [160] which has been described as an "extremely low" dosage. [87] Levels of testosterone were decreased by about 95% with the combination and by about 61% with cyproterone ...
Cyproterone is a potent antiandrogen, similarly to CPA. [5] [6] However, it has approximately three-fold lower potency as an antagonist of the androgen receptor (AR) relative to CPA. [6] Like CPA, cyproterone is actually a weak partial agonist of the AR, and hence has the potential for both antiandrogenic and androgenic activity in some ...
[125] [126] [127] Combined birth control pills containing different progestins result in SHBG levels that are increased 1.5- to 2-fold with levonorgestrel, 2.5- to 4-fold with desogestrel and gestodene, 3.5- to 4-fold with drospirenone and dienogest, and 4- to 5-fold with cyproterone acetate. [125]
Some inhibitors are selective and target only the 17,20-lyase function, while others inhibit both functions. [2] By inhibiting these enzymatic functions, CYP17A1 inhibitors prevent the conversion of pregnane steroids into androgens like testosterone. This action classifies them as androgen biosynthesis inhibitors and functional antiandrogens.
