For drug interaction purposes, the inhibitors and inducers of CYP3A metabolism listed above can alter serum concentrations of drugs that are dependent upon the CYP3A subfamily of liver enzymes, including CYP3A4, for elimination or activation. docetaxel, etoposide, vincristine; calcium channel blockers e.g. Lorcaserin. Cytochrome P450 (CYP450) are a group of enzymes encoded by the P450 genes and responsible for the metabolism of most drugs seen in clinical practice. It is metabolized by multiple enzymes including CYP2B6 that is primarily responsible for the formation of hydroxybupropion. 477 terms.

Therefore, it is difficult to define their respective contribution to drug metabolism and drug-drug interactions. Because many other commonly used drugs are moderate-to-potent inhibitors of CYP3A4, it is not surprising that drug toxicity of CYP3A4 substrates due to inhibition of CYP3A4 is relatively common. Its effect potentially could be stronger at 400 mg/day.l The classification is based on effect of 200 mg/day modafinil. BCRP: (1) AUC fold-increase is 1.5 with pharmacogenetic alteration of ABCG2 (421C>A) and (2) in vitro transported by BCRP expression systems.

Keep in mind that many drugs are metabolized by more than one CYP450 enzyme, and CYP3A4 may represent only one pathway. AUC: area under the concentration-time curve; CYP: cytochrome P450; DDI: drug-drug interaction. Drugs metabolized by CYP3A4 are called CYP3A4 substrates. and our CYP3A4 genetic polymorphisms are believed to be one of the important causes, leading to inter-individual variability in drug metabolism. The mnemonic SICKFACES.COM can be used to easily remember common CYP450 inhibitors. OATP1B1/OATP1B3: (1) AUC fold-increase is 2 with rifampin (single dose) or cyclosporine A co-administration or pharmacogenetic alteration of SLCO1B1 (521T>C); and (2) in vitro transported by OATP1B1 and/or OATP1B3 expression systems.
