Norethisterone · Micronor · Norlutin
Norethisterone (NET), also known as norethindrone, is a medication that is used in combination with estrogen or alone in hormonal contraceptives, menopausal hormone therapy, and in the treatment of gynecological disorders. It is a synthetic progestogen (or a progestin) of the 19-nortestosterone group and has similar effects to those of natural progesterone, including suppression of gonadotropins, ovulation inhibition, and endometrial transformation. In addition to its progestogenic activity, NET also has weak androgenic and estrogenic effects at high dosages.
ETHYNODIOL DIACETATE (297-76-7)
Continuin · Femulen · (3 beta, 17 alpha)-19-Norpregn-4-en-20-yne-3,17 diol Diacetate
Etynodiol diacetate, or ethynodiol diacetate, is a progestin of the 19-nortestosterone group which is used in oral contraceptives. It is the 3β,17β-diacetate ester of etynodiol, and acts as a rapidly converted prodrug of norethisterone, with etynodiol occurring as an intermediate. Etynodiol diacetate has weak androgenic activity, and, unlike most progestins but similarly to norethisterone and noretynodrel, also has some estrogenic activity.
