CYP2J2 Inhibitors

    CYP2J2 inducers include, but are not limited to, ketoconazole. See glossary page for more information.


    CYP2J2 inhibitors are compounds that reduce the activity of the CYP2J2 enzyme, which can reduce drug metabolism, potentially impacting the effects of drug therapy.

    CYP2J2 is a cytochrome P450 (CYP) enzyme that makes up less than 1% of total cytochrome P450 enzymes in the liver. Rather, CYP2J2 is expressed in high levels in the heart. CYP2J2 is involved in the metabolism of any medications that are CYP2J2 substrates. CYP2J2 inducers can reduce the body’s metabolism of any such medications, although there are currently very few medications that are known to rely on CYP2J2 for metabolism.[1]

    The table below outlines some of the most common or clinically relevant CYP2J2 inhibitors.[2][1][3] Importantly, this list is not exhaustive.
