Monitor

Plasma concentrations and effects of drugs that are CYP450 substrates may be altered following the initiation of interleukin (IL) inhibitors, tumor necrosis factor (TNF) blockers, or interferon (IFN) inhibitors in patients with chronic inflammatory diseases. The formation of hepatic CYP450 enzymes may be suppressed during infection and chronic inflammation by increased levels of certain cytokines (e.g., interleukins-1, -6, and -10; tumor necrosis factor alpha; interferons). Immunomodulating therapy that improves inflammation by targeting these cytokines may restore or normalize CYP450 enzyme levels resulting in increased or decreased metabolism of these substrates to active or inactive metabolites. The therapeutic target and disease state being treated may play a role in the significance of this interaction. The most evidence is currently for agents targeting the actions of IL-6 and in disease states with high levels of inflammation such as rheumatoid arthritis, rather than in patients with psoriasis and atopic dermatitis. In vitro studies showed that tocilizumab, an IL-6 inhibitor, has the potential to impact expression of various hepatic microsomal enzymes including CYP450 1A2, 2B6, 2C9, 2C19, 2D6, and 3A4. Its effects on CYP450 2C8 or transporters is unknown. In vivo studies with omeprazole (a substrate of CYP450 2C19 and 3A4) and simvastatin (a substrate of CYP450 3A4 and OATP 1B1) showed decreases of up to 28% and 57% in systemic exposure, respectively, one week following a single dose of tocilizumab. Likewise, simvastatin and simvastatin acid exposures decreased by 45% and 36%, respectively, in 17 patients with rheumatoid arthritis one week following a single 200 mg subcutaneous dose of sarilumab, another IL-6 inhibitor. A role for other interleukins such as IL-12, IL-17A, or IL-23 in the regulation of CYP450 enzymes has not been clearly established, and it is not known whether antagonists of these interleukins would similarly affect CYP450 metabolism. For example, in drug interaction studies, the IL-23 antagonists risankizumab and tildrakizumab, and the IL-17A antagonist ixekizumab demonstrated no clinically significant effects on the activity of CYP450 isoenzymes 1A2, 3A, 2C19, 2D6, or 2C9. Similarly, data evaluating this interaction are not available for the TNF blockers certolizumab and etanercept.

Management

Caution is advised when treatments targeting cytokines such as interleukins, tumor necrosis factors, or interferons are prescribed to patients receiving concomitant drugs that are CYP450 substrates, particularly those with narrow therapeutic ranges (e.g., antiarrhythmics, anticonvulsants, immunosuppressants, theophylline) or sensitive substrates where decreases in plasma levels may be significant or undesirable (e.g., oral contraceptives, statins, benzodiazepines, opioids). Clinical and/or laboratory monitoring should be considered following the initiation or withdrawal of such treatments, and the dosage(s) of the CYP450 substrate(s) adjusted accordingly. Clinicians should note that the effects of IL inhibitors, TNF blockers, and IFN inhibitors on CYP450 activities may persist for several weeks after stopping therapy. Individual product labeling for these products should be consulted for specific recommendations.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

ergotamine Food/Lifestyle

Applies to: ergotamine
Monitor

Grapefruit or grapefruit juice may increase the plasma concentrations of orally administered drugs that are substrates of the CYP450 3A4 isoenzyme. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Because grapefruit juice inhibits primarily intestinal rather than hepatic CYP450 3A4, the magnitude of interaction is greatest for those drugs that undergo significant presystemic metabolism by CYP450 3A4 (i.e., drugs with low oral bioavailability). In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict.

Management

Patients who regularly consume grapefruit or grapefruit juice should be monitored for adverse effects and altered plasma concentrations of drugs that undergo significant presystemic metabolism by CYP450 3A4. Grapefruit and grapefruit juice should be avoided if an interaction is suspected. Orange juice is not expected to interact with these drugs.
