Norgestrel 70-80 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 84-89 11849197-1 2002 AIMS: To examine the effects of an oral contraceptive containing ethinyloestradiol and norgestrel on intestinal and hepatic CYP3A activity using midazolam as a probe substrate. Norgestrel 87-97 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 124-129 28283499-8 2017 In addition to NGMN, we have also elucidated the biotransformation of norgestrel (NG), a downstream norgestimate and NGMN metabolite, and found that CYP3A4 and UGT1A1 have a major contribution to the elimination of NG with a combined fm value of 1.
