Interactions between your drugs

Moderate

dexAMETHasone panobinostat

Applies to: Baycadron (dexamethasone) and panobinostat

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of panobinostat, which is partially metabolized by the isoenzyme. The interaction has not been evaluated clinically, but simulations using physiologically-based pharmacokinetic (PBPK) models suggest an approximately 70% decrease in panobinostat systemic exposure in the presence of potent CYP450 3A4 inducers.

MANAGEMENT: Caution is advised during concomitant use of panobinostat with CYP450 3A4 inducers. The potential for decreased efficacy of panobinostat should be considered.

Drug and food interactions

Moderate

panobinostat food

Applies to: panobinostat

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of panobinostat. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Increased exposure to panobinostat may increase the risk of adverse effects such as nausea, vomiting, diarrhea, anorexia, peripheral edema, cardiotoxicity, ECG abnormalities, electrolyte disturbances, bleeding complications, hepatotoxicity, and myelosuppression.

Food may delay the rate of absorption of panobinostat, but does not significantly affect the overall extent of absorption. When a single oral dose of panobinostat was administered to 36 patients with advanced cancer 30 minutes after a high-fat meal, panobinostat peak plasma concentration (Cmax) and systemic exposure (AUC) were approximately 44% and 16% lower, respectively, compared to administration under fasting conditions. The median time to maximum concentration (Tmax) was prolonged by 2.5 hours.

MANAGEMENT: Patients should avoid consumption of grapefruit or grapefruit juice during treatment with panobinostat. The manufacturer also recommends avoiding star fruit, Seville oranges, pomegranate, and pomegranate juice. Panobinostat may be administered with or without 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.
