Ethinyle-estradiol

The two synthetic steroidal estrogens which have attained the greatest degree of therapeutic use are ethinyl estradiol [57-63-6] (EE) (5) and its 3-methyl ether, mestranol [72-33-3]((5). In contrast to the naturally occurring estrone derivatives, these acetylenic analogues are orally active and are the main estrogenic components of combination oral contraceptives (see Contraceptives) and certain estrogen replacement products. [Pg.231]

A major obstacle to the use of naturally occurring estrogens for the purpose of contraception was extensive first-pass hepatic metabolism and hence inactivation of the compounds when given orally. The addition of an ethinyl group at the 17 position made estradiol orally active. Ethinyl estradiol is a potent oral estrogen and... [Pg.389]

Taking the contraceptive hormones provides health benefits not related to contraception, such as regulating the menstrual cycle and decreased blood loss, and incidence of iron deficiency anemia, and dysmenorrhea Health benefits related to the inhibition of ovulation include a decrease in ovarian cysts and ectopic pregnancies. hi addition, there is a decrease in fibrocyctic breast disease, acute pelvic inflammatory disease endometrial cancer, ovarian cancer, maintenance of bone density, and symptoms related to endometriosis in women taking contraceptive hormones. Newer combination contraceptives such as norgestimate and ethinyl estradiol... [Pg.547]

Cyproterone acetate (CPA) is a progestational antiandrogen that blocks the androgen receptors. It is combined with ethinyl estradiol in an oral contraceptive formulation, which is indicated in female acne patients with a high level of seborrhea, therapy resistant papulo-pustular acne or acne conglobata not responding to other treatments. [Pg.131]
