Note that the CYP3A4 enzyme is particularly suscep-tible to enzyme inducers, and marked reductions in the plasma concentrations of CYP3A4 substrates may occur. Carbamazepine reduces midazolam concentrations, and it is therefore likely that other drugs that are potent inducers of CYP3A4 … [34] Ligands. CYP3A4 inducers tend to reduce plasma concen- trations of CYP3A4 substrates, resulting in reduced efficacy of the substrate. TKIs as CYP inducers. ANTIMETRIC. The ability of drugs to act as inducers, inhibitors, or substrates for CYP3A is predictive of whether concurrent administration of these compounds with a known CYP3A substrate might lead to altered drug disposition, efficacy or toxicity. Strong inhibitors of inducers of CYP3A4 are unlikely to significantly alter baricitinib exposure.
