For more information about StivargaseeFull Prescribing Information. At the other extreme, ultrarapid metabolisers metabolise the drug rapidly, resulting in a lack of therapeutic response in these individuals. Note: Index inducers predictably induce metabolism via a given pathway and are commonly used in prospective clinical DDI studies. For example, a patient taking the potent CYP3A4 inducer rifampin may have a roughly 90% reduction in serum concentrations of CYP3A4 substrates, such as buspirone, triazolam, and verapamil. The selectivity and potency of inhibitors should be verified using the same experimental conditions with probe substrates for each CYP enzyme. See section IV.A.2 of the FDA guidance for industry entitled Clinical Drug Interaction Studies Cytochrome P450 Enzyme- and Transporter-Mediated Drug Interactions (January 2020) for more details. Many drugs that are CYP3A4 substrates, inhibitors, and inducers are also substrates, inhibitors, or inducers of the ABC transport protein known as P-glycoprotein. the particular CYP family induced and the potency of the induction. 155 US Highway 46, Suite 202 Cami_Chi . CYP2C9 is involved in many drug interactions.Some of the substrates that warrantparticular attention are warfarin,phenytoin, and oral hypoglycemics.Some of the more potent CYP2C9inhibitors include amiodarone, fluorouracil,metronidazole, miconazole (especially systemic use), and sulfamethoxazole (usually combined withtrimethoprim).
