Also known as Ovrette
Norgestrel is a progestin used in hormonal contraceptives. Norgestrel is a mixture of two stereoisomers, dextro-norgestrel (CAS# 797-64-8) and levo-norgestrel (CAS# 797-63-7). Only levonorgestrel is biologically active. Therefore, while some medications may contain dextronorgestrel, they are often labeled in terms of their levonorgestrel content only, ignoring the inert isomer. It is used in the hormonal contraceptive Microgynon 30, among others.Source: Wikipedia
