Description:
Levonorgestrel is a synthetic progestational hormone with actions similar to those of progesterone and about twice as potent as its racemic or[+-]-isomer[norgestrel][1]. It is a kind of emergency contraception, referring as a drug or device used to prevent pregnancy after unprotected sexual intercourse[including sexual assault] or after a recognized contraceptive failure[1]. It is used for contraception, control of menstrual disorders, and treatment of endometriosis. Levonorgestrel is marketed mostly as a combination oral contraceptive under several brand names such as Alesse, Triphasil, and Min-Ovral. It is also marketed under the brand of Plan B.
Levonorgestrel was discovered in 1963 and was introduced for medical use together with ethinylestradiol in 1970.[2, 3] It is listed as an essential medicine by the World Health Organization, being the most effective and safe medicines needed in a health system.[4] It is available as a generic medication.[5]
Levonorgestrel is a levo-isomer of Norgestrel. The progestins include the naturally occurring hormone progesterone, 17a-acetoxyprogesterone derivatives in the pregnane series, 19-nortestosterone derivatives(estranes), and norgestrel and related compounds in the gonane series. The 19-nortestosterone derivatives were developed for use as progestins in oral contraceptives, and while their predominant activity is progestational, they exhibit androgenic and other activities. The gonanes are a more recently developed series of "19-nor" compounds, containing an ethyl rather than a methyl substituent in the 13-position, and they have diminished androgenic activity.
