CYP2E1 Inducers

    CYP2E1 inducers include, but are not limited to, isoniazid and ethanol. See glossary page for more information.

    Summary

    CYP2E1 inducers are compounds that increase the activity of the CYP2E1 enzyme, which can increase drug metabolism, potentially impacting the effects of drug therapy.

    CYP2E1 is a cytochrome P450 (CYP) enzyme with a minor role in drug metabolism as well as in the metabolism of some industrial chemicals and organic solvents. CYP2E1 is involved in the metabolism of any medications that are CYP2E1 substrates. CYP2E1 inhibitors can increase the body’s metabolism of any of these substances.

    The table below outlines some of the most common or clinically relevant CYP2E1 inducers.[1][2][3] Importantly, this list is not exhaustive.

    Isoniazid
    Ethanol
