Interactions between your drugs

Moderate

aprepitant PONATinib

Applies to: aprepitant and ponatinib

MONITOR: Coadministration with inhibitors of CYP450 3A4 may increase the plasma concentrations of ponatinib, which is a substrate of the isoenzyme. In 22 healthy volunteers, administration of a single 15 mg oral dose of ponatinib in combination with the potent CYP450 3A4 inhibitor ketoconazole (400 mg daily) increased ponatinib peak plasma concentration (Cmax) and systemic exposure (AUC) by 47% and 78%, respectively, compared to administration of ponatinib alone. No data are available for use with less potent CYP450 3A4 inhibitors.

MANAGEMENT: Caution is advised if ponatinib is used in combination with moderate CYP450 3A4 inhibitors. Patients should be monitored for potentially increased side effects such as thromboembolism, ischemia, congestive heart failure, hypertension, hepatotoxicity, pancreatitis, myelosuppression, hemorrhage, and fluid retention.

Drug and food interactions

Moderate

PONATinib food

Applies to: ponatinib

GENERALLY AVOID: Coadministration with grapefruit juice is likely to increase the plasma concentrations of ponatinib, which is primarily metabolized by CYP450 3A4. However, the interaction has not been studied. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit.

MANAGEMENT: The consumption of grapefruit, grapefruit juice, and supplements that contain grapefruit extract should be avoided during treatment with ponatinib.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
