To date, more than 30 polymorphic CYP3A4 alleles have been characterized, which may contribute to individual differences in CYP3A4-dependent drug clearance Lamba et al (2002). Strong CYP3A4 inhibitors were used in 60.8%, 45.6%, and 10.8% of patients during induction, consolidation, and maintenance, respectively. In some cases, this can lead to a fatal interaction with drugs like astemizole or terfenadine. CYP3A4 inhibitors, such as grapefruit, can interact with certain medications by inhibiting the liver enzyme that metabolizes many drugs. Ketoconazole is a potent CYP3A4/5 inhibitor and, until recently, recommended by the Food and Drug Administration (FDA) and the European Medicines Agency as a strong CYP3A4/5 inhibitor in clinical drug-drug interaction (DDI) studies. endstream endobj startxref CYP3A4 is mainly involved in the metabolism of ART drugs, including NNRTIs, PIs, and integrase inhibitors. About 347 SNPs have been identified in the CYP3A4 gene (CYP3A4*1A: wild-type), 25 of which are of Drugs that Inhibit CYP3A4; Increase Gleevec levels. These results suggest that combining FLT3 TKIs with CYP3A4 inhibitors could be a promising strategy toward improving the activity of FLT3 TKIs. I read that modafinil (a wakefulness enhancer which induces CYP3A4) "reduce[s] the contraceptive effectiveness of combined hormonal contraceptives" (the specific example was ethinylestradiol).

Since the majority of several population groups have non-functioning variants, for this gene NOT carrying a variant may impact your metabolism of certain drugs by increasing enzyme function. They stop the actual substrates of the glycoprotein receptors from binding to the receptor, so inhibit platelets from sticking together to form a thrombus, which can lead to stroke, myocardial infarction or deep vein thrombosis . In comparison, the number of patients co-medicated with long-term CYP3A4 inhibitors increased by 4.6%, from 9533 patients in 2004 to 9968 patients in 2006 (Figure 1).
