The inhibitors listed here can be used together with other information, such as metabolic profiles obtained from single enzyme expression systems. Start studying CYP3A4 - Substrates/ Inhibitors/ Inducers. About 347 SNPs have been identified in the CYP3A4 gene (CYP3A4*1A: wild-type), 25 of which are of Strong CYP3A4 inhibitors were used in 60.8%, 45.6%, and 10.8% of patients during induction, consolidation, and maintenance, respectively. Mechanism-based inhibition of CYP3A4 can be an inhibition or inactivation of existing CYP3A4 via the formation of a metabolite intermediate complex.

What is the mechanism of the "boost" effect. We found that CYP3A4 plays a major role in BMSC-mediated inhibition in the activity of 3 different FLT3 TKIs (sorafenib, quizartinib, and gilteritinib) against FLT3/ITD acute myeloid leukemia (AML). Eating or drinking these can cause adverse effects on drug metabolism, either increasing the efficiency of the drug or decreasing the effect.

The CYP3A4-inhibition is usually irreversible, meaning that it's "knocked-out" until new CYP3A4 is produced; 3-12 hours. Inhibition of CYP2C19 may block the activation of clopidogrel, which could reduce its effects. Drugs that inhibit CYP3A4 activity will almost always increase the plasma concentrations of the CYP3A4 substrate medications. Substrates of CYP3A4 constitute a variety of pharmacological agents, including some benzodiazepines, immunosuppressants, 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (i.e., statins), human immunodeficiency virus (HIV) protease inhibitors, and steroid hormones, as well as a number of toxins, including aflatoxin B1 and benzo[a]pyrene 7,8-dihydrodiol (Liu et al.
