CYP3A4 is a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases that catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids, and other lipids components.lthough CYP3A4 is predominantly found in the liver, it is also present in other organs and tissues of the body, where it may play an important role in metabolism. CYP3A4 in the intestine plays an important role in the metabolism of certain drugs.
The CYP2D6 enzyme is not needed to activate raloxifene (brand name: Evista, a sister medicine to tamoxifen, used to reduce the risk of developing hormone-receptor-positive breast cancer and treat osteoporosis in postmenopausal women).he body uses an enzyme called CYP2D6 to convert tamoxifen into its active form. Two things can interfere with the bodyâs ability to make this happen: a flaw in the CYP2D6 enzyme and certain medications that block the effectiveness of this enzyme.
