Edit list (add/remove drugs)

Interactions between your drugs

Moderate

PAZOPanib darolutamide

Applies to: pazopanib and Nubeqa (darolutamide)

GENERALLY AVOID: Coadministration with darolutamide may increase the plasma concentrations of drugs that are substrates of the breast cancer resistance protein (BCRP) transporter. The proposed mechanism is decreased clearance due to inhibition of BCRP-mediated intestinal and hepatobiliary efflux by darolutamide. When rosuvastatin, a known BCRP substrate, was administered concomitantly with darolutamide, mean rosuvastatin peak plasma concentration (Cmax) and systemic exposure (AUC) increased by approximately 5-fold.

MANAGEMENT: Concomitant use of darolutamide with drugs that are BCRP substrates should be avoided when possible. If coadministration is required, patients should be monitored carefully for increased adverse reactions of these drugs and dosing adjusted as necessary.

Drug and food interactions

Major

PAZOPanib food

Applies to: pazopanib

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of pazopanib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. Although not studied, the interaction may increase the risk of QT interval prolongation and torsade de pointes arrhythmia as well as severe and fatal hepatotoxicity associated with the use of pazopanib.

ADJUST DOSING INTERVAL: Food increases the oral bioavailability of pazopanib. The mechanism of interaction is unknown. Administration of pazopanib with a high-fat or low-fat meal results in an approximately 2-fold increase in peak plasma concentration (Cmax) and systemic exposure (AUC).

MANAGEMENT: Patients treated with pazopanib should avoid consumption of grapefruit, grapefruit juice, and any supplement containing grapefruit extract. Pazopanib should be administered at least one hour before or two hours after a meal.

Moderate

darolutamide food

Applies to: Nubeqa (darolutamide)

ADJUST DOSING INTERVAL: Food enhances the oral absorption of darolutamide. According to the prescribing information, bioavailability of darolutamide increased by 2.0 to 2.5-fold when administered with food. A similar increase in exposure was observed for the active metabolite keto-darolutamide.

MANAGEMENT: Darolutamide should be administered with food.

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.
