Interactions between your drugs

Moderate

PONATinib seladelpar

Applies to: ponatinib and seladelpar

MONITOR: Coadministration with inhibitors of the breast cancer resistance protein (BCRP) may increase the plasma concentrations and effects of seladelpar, which is a substrate of this efflux transporter. A clinical drug interaction study found that the systemic exposure (AUC) and maximum plasma concentration (Cmax) of a single dose of seladelpar (10 mg) increased by 2.1- and 2.9-fold, respectively, when administered with a single dose of the BCRP inhibitor cyclosporine (600 mg) in healthy subjects.

MANAGEMENT: Close monitoring for adverse reactions is advised if seladelpar is administered concurrently with a BCRP inhibitor. Liver tests should be monitored as clinically indicated and treatment with seladelpar may need to be held or permanently discontinued if liver tests worsen and/or clinical hepatitis develops. The labeling of the inhibitor should also be consulted as some inhibitors may continue to have effects on this transporter even after the agent has been discontinued.

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.
