It is important to note that not all drugs within a class of medications are known to be inhibitors of CYP3A4. Kinase Inhibitor. Valproate Isoniazid Note that the CYP3A4 enzyme is particularly suscep-tible to enzyme inducers, and marked reductions in the plasma concentrations of CYP3A4 substrates may occur. Inhibitors of CYP1A2 can be classified by their potency, such as: Strong inhibitor being one that causes at least a 5-fold increase in the plasma AUC values of sensitive substrates metabolized through CYP1A2, or more than 80% decrease in clearance thereof. CYP3A4 inducers Pazopanib Ketoconazole - If co-administration of strong CYP3A4 inhibitors is warranted, reduce the dose of pazopanib to 400 mg In patients for whom CYP3A4 inducers are indicated, alternative agents with less enzyme induction potential should be selected CYP3A4 inducers, such as carbamazepine and rifampicin, may reduce the plasma concentrations of atorvastatin and simvastatin. ** Recommend use of 2 structurally unrelated CYP3A4/5 substrates for evaluation of in vitro CYP3A inhibition. Carbamazepine reduces midazolam concentrations, and it is therefore likely that other drugs that are potent inducers of CYP3A4 will interact similarly with midazolam. Where classes of agents are listed, there may be exceptions within the class.
