What is Norgestrel?
Description
Norgestrel is a synthetic progestin and a racemic mixture of dextronorgestrel and levonorgestrel , of which levonorgestrel is the biologically active component. In vivo, norgestrel administered via intrauterine device (IUD) prevents pregnancy in rats. Formulations containing nogestrel have been used as contraceptives.

What are the applications of Application
Norgestrel is a synthetic progesterone analog
Indications
Norgestrel in combination with ethinyl estradiol is indicated for the prevention of pregnancy in women who elect to use this product as a method of contraception.
Background
Norgestrel is synthetic steroidal progestin that is used in combination with ethinyl estradiol for oral contraception. Norgestrel is composed of a racemic mixture of two stereoisomers, dextronorgestrel and levonorgestrel. However, only the levorotary enantiomer (levonorgestrel) is biologically active.
Definition
ChEBI: Levonorgestrel is a 17beta-hydroxy steroid, a 3-oxo-Delta(4) steroid and a terminal acetylenic compound. It has a role as a contraceptive drug, a progestin, a synthetic oral contraceptive and a female contraceptive drug. It is functionally related to a norgestrel. It is an enantiomer of a dexonorgestrel.
brand name
Ovrette (Wyeth).
General Description
Norgestrel, (17α)-(±)-13-ethyl-17-hydroxy-18,19-dinorpregn-4-en-20-yn-3-one, and levonorgestrel, (17α)-(-)-13-ethyl-17-hydroxy-18,19-dinorpregn-4-en-20-yn-3-one,have a C13 ethyl group instead of the C13 methyl but haveprogestational properties similar to those of norethindrone,with decreased androgenic effects. The ethyl group apparentlyprovides unfavorable steric interactions with the ARthat reduce the affinity compared with that with the PRs.Norgestrel is a racemic mixture, while levonorgestrel is thesingle active levorotatory enantiomer. Norgestrel is usedonly in oral contraceptives. Levonorgestrel is used in bothoral combination birth control products and polymeric implantsthat provide contraception for up to 5 years.
