Norethisterone Enanthate
Norethisterone enanthate (pronunciation: nor-eth-iss-ter-own en-an-thate), also known as norethindrone enanthate, is a progestin medication which is used in birth control and menopausal hormone therapy. It is not available in the United States but is widely used in other countries.
Etymology
The term "norethisterone" is derived from "nor-", a prefix used in organic chemistry to denote a molecule that is a demethylated derivative of another molecule, and "ethisterone", a progestin that is related to testosterone. The "enanthate" part of the name refers to the enanthate ester, a type of carboxylic acid ester.
Pharmacology
Norethisterone enanthate is a progestogen ester and a long-acting prodrug of norethisterone in the body. It works by preventing the release of an egg during the menstrual cycle, thickening the mucus in the cervix to make it harder for sperm to reach the uterus, and thinning the lining of the uterus to make it less likely for a fertilized egg to attach.
