Minor

donepezil eliglustat

Applies to: Aricept ODT (donepezil) and eliglustat

Coadministration with inhibitors of CYP450 2D6 and/or 3A4 may increase the plasma concentrations of donepezil, which is primarily metabolized by these isoenzymes. In a 7-day crossover study in 18 healthy volunteers, the potent CYP450 3A4 inhibitor ketoconazole (200 mg once daily) increased the mean peak plasma concentration (Cmax) and systemic exposure (AUC) of donepezil (5 mg once daily) by approximately 36% each. The clinical relevance of these increases is unknown. A prolonged duration of monitoring for adverse effects may be required depending on the elimination half-life of the concomitant drug. For example, it should be noted that rolapitant, a moderate CYP450 2D6 inhibitor, can increase plasma concentrations and the risk of adverse effects of donepezil for at least 28 days after administration of rolapitant.

Drug and food interactions

Major

eliglustat food

Applies to: eliglustat

GENERALLY AVOID: Grapefruit juice may significantly increase the systemic exposure to eliglustat. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Because eliglustat is predicted to cause prolongation of the PR, QTc, and QRS cardiac intervals at substantially elevated plasma concentrations, consumption of grapefruit juice during treatment may increase the risk of bradycardia, atrioventricular block, cardiac arrest, and serious ventricular arrhythmias such as torsade de pointes.

MANAGEMENT: Patients treated with eliglustat should avoid consumption of grapefruit and grapefruit juice.

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.
