Alunbrig and Alcohol/Food Interactions

There is 1 alcohol/food/lifestyle interaction with Alunbrig (brigatinib).

Moderate

brigatinib food

Moderate Food Interaction

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of brigatinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Itraconazole, a potent CYP450 3A4 inhibitor, has been shown to double brigatinib systemic exposure (AUC) in healthy volunteers. Increased exposure to brigatinib may increase the risk of adverse effects such as nausea, vomiting, diarrhea, hypertension, bradycardia, hyperglycemia, visual disturbances, lymphopenia, anemia, and elevations in pancreatic enzymes and creatine phosphokinase.

Food does not significantly affect the oral bioavailability of brigatinib. When brigatinib was administered to healthy volunteers after a high-fat meal (920 calories; 59 g fat, 58 g carbohydrates, 40 g proteins), brigatinib peak plasma concentration (Cmax) decreased by 13% and systemic exposure (AUC) did not change compared to administration after overnight fasting.

MANAGEMENT: Brigatinib may be taken with or without food. Patients should avoid consumption of grapefruit and grapefruit juice during treatment with brigatinib.

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.
