Interactions between your drugs

Moderate

fenofibrate avatrombopag

Applies to: fenofibrate and avatrombopag

MONITOR: Coadministration with fenofibrate may increase the plasma concentrations and risk of adverse effects of drugs that are substrates of CYP450 2C19, 2A6, and 2C9 isoenzymes. The proposed mechanism, based on in vitro data, is decreased clearance due to fenofibrate-mediated inhibition of CYP450 2C19, 2A6, and 2C9.

MANAGEMENT: Until more information is available, caution is advised if fenofibrate is used concomitantly with drugs that are substrates of CYP450 2C19, 2A6, or 2C9 isoenzymes, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring should be considered whenever fenofibrate is added to or withdrawn from therapy with these drugs. Patients should be monitored for the development of adverse effects.

Drug and food interactions

Moderate

avatrombopag food

Applies to: avatrombopag

ADJUST DOSING INTERVAL: Food reduces the variability in oral absorption and bioavailability of avatrombopag. According to the product labeling, avatrombopag peak plasma concentration (Cmax) and systemic exposure (AUC) were not affected when administered with either a low-fat (500 calories; 3 g fat, 15 g proteins, 108 g carbohydrates) or high-fat (918 calories; 59 g fat, 39 g proteins, 59 g carbohydrates) meal. However, the variability of avatrombopag exposure was reduced by 40% to 60% with food, and the time to reach Cmax was delayed by 0 to 2 hours relative to the fasted state.

MANAGEMENT: To ensure consistent absorption and plasma drug levels, avatrombopag should be taken 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.
