Drug and food interactions
crizotinib food
Applies to: crizotinib
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of crizotinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. Because crizotinib is associated with concentration-dependent prolongation of the QT interval, increased levels may potentiate the risk of ventricular arrhythmias such as torsade de pointes and sudden death.
Food has no significant effect on the gastrointestinal absorption of crizotinib. According to the product labeling, a high-fat meal reduced crizotinib peak plasma concentration (Cmax) and systemic exposure (AUC) by approximately 14%.
MANAGEMENT: Patients treated with crizotinib should avoid consumption of grapefruit, grapefruit juice, and any supplement containing grapefruit extract. Crizotinib may be taken without regards to food.
