Keep in mind that many drugs are metabolized by more than one CYP450 enzyme, and CYP3A4 may represent only one pathway. CYP3A4 metabolizes more than 1900 drugs: 1033 act as substrates (897 major, 136 minor); 696, as inhibitors (118 weak, 437 moderate, and 141 strong); and 241, as inducers of the CYP3A4 enzyme [113]. Required fields are marked *. 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. St. John's wort.

A higher dose (400 mg/day) modafinil had a larger induction effect on CYP3A. Its effect potentially could be stronger at 400 mg/day.l The classification is based on effect of 200 mg/day modafinil. AUC: area under the plasma concentration-time curve. This has the potential to cause drug interactions, thus increasing the risk of debilitating and even fatal adverse drug events. OATP1B1/OATP1B3: (1) AUC fold-increase is 2 for at least one of clinical substrates in Table 5-1 with co-administration; and (2) in vitro inhibitor of OATPB1 and/or OATP1B3. Consequently, this decreases drug metabolism in the body and increases the potential for toxicity. The mnemonic SICKFACES.COM can be used to easily remember common CYP450 inhibitors.
