Edit list (add/remove drugs)

Interactions between your drugs

Moderate

dronedarone cabazitaxel

Applies to: Multaq (dronedarone) and Jevtana (cabazitaxel)

MONITOR: Coadministration with inhibitors of CYP450 3A4 may increase the plasma concentrations of cabazitaxel, which is primarily metabolized by the isoenzyme. However, no formal drug interaction studies have been conducted.

MANAGEMENT: Caution is advised if cabazitaxel is prescribed with CYP450 3A4 inhibitors. Pharmacologic response to cabazitaxel should be monitored more closely whenever a CYP450 3A4 inhibitor is added to or withdrawn from therapy, and the cabazitaxel dosage adjusted as necessary. Regular monitoring of peripheral blood counts between treatment cycles is recommended, and patients should be advised to contact their physician if they experience potential signs and symptoms of cabazitaxel toxicity such as infection, fever, chills, diarrhea, unusual bruising or bleeding, and burning, tingling, or numbness in the hands and feet.

Drug and food interactions

Major

dronedarone food

Applies to: Multaq (dronedarone)

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of dronedarone. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. According to the product labeling, administration with grapefruit juice resulted in a 2.5-fold increase in dronedarone peak plasma concentration and a 3-fold increase in systemic exposure. Because dronedarone 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.

ADJUST DOSING INTERVAL: Food increases the oral bioavailability of dronedarone. The mechanism of interaction is unknown. According to the product labeling, the absolute bioavailability of dronedarone increases from about 4% when administered in the fasted state to approximately 15% when administered with a high-fat meal.

MANAGEMENT: Patients treated with dronedarone should avoid consumption of grapefruit, grapefruit juice, and any supplement containing grapefruit extract. Dronedarone should be taken twice daily with the morning and evening meals.

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.
