Chlormadinone acetate (CMA) Powder (302-22-7) Description:

Chlormadinone acetate, a synthetic progestogen, was introduced in 1965 as a component in oral contraceptive preparations. Chlormadinone acetate sometimes abbreviated as CMA, and also known as 17α-acetoxy-6-chloro-6-dehydroprogesterone

Chlormadinone Acetate powder is the actetate salt form of chlormadinone, a synthetic progestin with antiandrogenic and antigonadotropic effects. Chlormadinone acetate (CMA) is a potent progesterone receptor (PR) agonist, a partial androgen receptor (AR) antagonist and a weak glucocorticoid receptor (GR) antagonist. Chlormadinone powder binds to PRs, which induces the expression of progesterone-responsive genes. In addition, chlormadinone blocks ARs in target organs and reduces the activity of skin 5 alpha-reductase; thus inhibiting androgen production and signaling. Through the negative feedback action on the hypothalamus-pituitary system, chlormadinone also suppresses gonadotropin secretion, which prevents ovarian and adrenal androgen production. Therefore, this agent decreases endometrial thickness, increases the viscosity of cervical mucus, inhibits ovulation and suppresses follicular growth and maturation.

Chlormadinone acetate is a steroidal progestin with additional antiandrogen and antigonadotropic (and by extension antiestrogenic) effects. CMA powder has been used in the treatment of vaginal bleeding, oligomenorrhea, polymenorrhea, hypermenorrhea, secondary amenorrhea, and endometriosis. It has also been used clinically as a hormonal contraceptive, and in part due to its capacity to lower estrogen levels, but also for improved effectiveness in contraception, chlormadinone has frequently been combined with ethinyl estradiol for this purpose.
