Medical and Biotech [MESH] Definitions

ETHINYL ESTRADIOL and NORGESTREL given in fixed proportions. It has proved to be an effective contraceptive (CONTRACEPTIVES, ORAL, COMBINED).

A semisynthetic alkylated ESTRADIOL with a 17-alpha-ethinyl substitution. It has high estrogenic potency when administered orally, and is often used as the estrogenic component in ORAL CONTRACEPTIVES.

A synthetic progestational hormone with actions similar to those of PROGESTERONE but functioning as a more potent inhibitor of ovulation. It has weak estrogenic and androgenic properties. The hormone has been used in treating amenorrhea, functional uterine bleeding, endometriosis, and for contraception.

The 3-methyl ether of ETHINYL ESTRADIOL. It must be demethylated to be biologically active. It is used as the estrogen component of many combination ORAL CONTRACEPTIVES.

The 3-cyclopentyl ether of ETHINYL ESTRADIOL. After gastrointestinal absorption, it is stored in ADIPOSE TISSUE, slowly released, and metabolized principally to the parent compound. It has been used in ESTROGEN REPLACEMENT THERAPY. (From AMA Drug Evaluations Annual, 1992, p1011)
