Note: Strong, moderate, and weak inducers are drugs that decreases the AUC of sensitive index substrates of a given metabolic pathway by 80%, 50% to <80%, and 20% to <50%, respectively. Note: Many of these chemical inhibitors are not specific for an individual CYP enzyme. We present at international symposiums on GIST, support global advocacy issues, and work to establish alliances and collaborations. Drugs that inhibit CYP3A4 activity will almost always increase the plasma concentrations of the CYP3A4 substrate medications. While we do make an effort to keep this list updated, it may not be complete. Therefore, it is difficult to define their respective contribution to drug metabolism and drug-drug interactions.
