Interactions between your drugs

Moderate

lapatinib capmatinib

Applies to: Tykerb (lapatinib) and capmatinib

GENERALLY AVOID: Coadministration with capmatinib may increase the plasma concentrations and risk of adverse effects of drugs that are substrates of P-glycoprotein (P-gp) and/or breast cancer resistance protein (BCRP) transporters, such as digoxin and rosuvastatin. The proposed mechanism is decreased clearance due to capmatinib-mediated inhibition of intestinal P-gp and/or BCRP efflux transport proteins. Coadministration with capmatinib increased the systemic exposure (AUC0-INF) and peak plasma concentration (Cmax) of digoxin (a P-gp substrate) by 47% and 74%, respectively. Concomitant use of capmatinib increased the AUC0-INF and Cmax of rosuvastatin (a BCRP substrate) by 108% and 204%, respectively.

MANAGEMENT: Coadministration of capmatinib with drugs that are substrates of P-gp and/or BCRP should generally be avoided. However, if concomitant use is unavoidable, caution is advised, particularly with drugs that have a narrow therapeutic range. Clinical and laboratory monitoring should be considered whenever capmatinib is added to or withdrawn from therapy with these drugs, and dosages adjusted as necessary. Patients should be monitored for the development of adverse effects.

Drug and food interactions

Moderate

lapatinib food

Applies to: Tykerb (lapatinib)

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of lapatinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits.

ADJUST DOSING INTERVAL: Food can significantly increase the oral bioavailability of lapatinib. According to the manufacturer, lapatinib peak plasma concentration (Cmax) was approximately 2.5- and 3-fold higher and systemic exposure (AUC) 3- and 4-fold higher when administered with a low fat meal (5% fat; 500 calories) or with a high-fat meal (50% fat; 1000 calories), respectively, compared to fasting. Dividing the daily dose also resulted in an approximately 2-fold higher systemic exposure at steady state compared to the same total dose administered once daily.

MANAGEMENT: Patients treated with lapatinib should preferably avoid the consumption of grapefruit or grapefruit juice. The manufacturer recommends that lapatinib be administered at least one hour before or one hour after a meal. The lapatinib dose is administered once daily and should not be divided.

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.
