However, blood concentration–guided dose-adjustment of immunosuppressants should be applied carefully because increased metabolism can evoke elevation of toxic metabolite formation (e.g., ciclosporin). Note that each number in parentheses [1, 2, 3, etc.] Sulfaphenazole Cotrimoxazole Moderate CYP3A4 inhibitors. based inhibitors of CYP3A4. Ciprofloxacin based inhibitors of CYP3A4. Tipranavir Some drugs, such as clarithromycin, itraconazole, and ketoconazole, are particularly potent inhibitors of CYP3A4; patients on these drugs may have markedly reduced CYP3A4 activity. Aprepitant Goldenseal is a potent inhibitor of both CYP3A4 and CYP2D6 enzyme activity. Asenapine Diltiazem Roxithromycin Norfloxacin more than one inhibitor suggests that the clinical effect of drug interaction with herbs and foodstuffs could be better understood by studying the mixture of inhibitors and/or an extract of these. Celecoxib Many supplements can also inhibit (and in some cases, activate) CYP3A4 and interact with many of the same medications. Gestodene Delavirdine For example, St. John's wort is a potent inducer of CYP3A4, which is mediated by activating the orphan pregnane X receptor. Six phytochemicals (Geranin, Apigenin, Fisetin, Luteolin, Phthalic acid and Gallic acid) were predicted to be inhibitors of CYP3A4 and, may slowdown elimination of PIs … The liver enzyme CYP3A4 is the key body mechanism for metabolizing pain medications. This is a list of cytochrome P450 modulators, or inhibitors and inducers of cytochrome P450 enzymes. Nicardipine ... Ubrelvy is broken down in your liver by an enzyme (a type of protein) called CYP3A4. Nifedipine Quinidine It may be associated with methadone overdose and fatalities (228 cases) [3]. Telaprevir Moclobemide Like cytochrome P450s (CYP3A4), Pgp is vulnerable to inhibition, activation, or induction by herbal constituents. Haloperidol Certain foods and herbs help the body reverse the process of aromatization . Moderate CYP3A4 inhibitors. Clarithromycin Nuclear receptors PXR and CAR activate CYP3A4 [10].
