Interactions between your drugs

Moderate

ranolazine vinCRIStine liposome

Applies to: ranolazine and vincristine liposome

MONITOR: Coadministration with ranolazine may increase the plasma concentrations of drugs that are primarily metabolized by the CYP450 3A4 isoenzyme. The mechanism is reduced clearance due to inhibition of CYP450 3A4 by ranolazine. The interaction may be significant for sensitive CYP450 3A4 substrates or those that demonstrate a narrow therapeutic index.

MANAGEMENT: Caution is advised if ranolazine is used in combination with sensitive CYP450 3A4 substrates or those that demonstrate a narrow therapeutic index (e.g., ergot alkaloids, colchicine, fentanyl, macrolide immunosuppressants, midazolam, triazolam, vinca alkaloids). Dosage adjustments as well as clinical and laboratory monitoring may be appropriate whenever ranolazine is added to or withdrawn from therapy.

Drug and food interactions

Major

ranolazine food

Applies to: ranolazine

GENERALLY AVOID: Grapefruit and grapefruit juice may significantly increase the plasma concentrations of orally administered ranolazine. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Because ranolazine prolongs QT interval in a dose-dependent manner, high plasma levels of ranolazine may increase the risk of ventricular arrhythmias such as ventricular tachycardia, ventricular fibrillation, and torsade de pointes.

MANAGEMENT: Patients treated with ranolazine should avoid consumption of grapefruit juice and other grapefruit products if possible. Otherwise, the dosage of ranolazine should be limited to 500 mg twice a day.

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.
