Interactions between your drugs

Moderate

ixabepilone ribociclib

Applies to: ixabepilone and ribociclib

MONITOR: Coadministration with inhibitors of CYP450 3A4 may increase the plasma concentrations of ixabepilone, which is primarily metabolized by the isoenzyme. According to the product labeling, administration of ixabepilone in combination with the potent inhibitor ketoconazole resulted in a 79% increase in ixabepilone systemic exposure (AUC) compared to treatment without ketoconazole. The effect of mild or moderate inhibitors such as erythromycin, fluconazole, or verapamil on exposure to ixabepilone has not been studied.

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 Pharmacologic response to ixabepilone should be monitored more closely whenever a CYP450 3A4 inhibitor is added to or withdrawn from therapy, and the ixabepilone dosage adjusted as necessary.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

Drug and food interactions

Moderate

ixabepilone food

Applies to: ixabepilone

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of ixabepilone. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits.

MANAGEMENT: Patients treated with ixabepilone should avoid the consumption of grapefruit or grapefruit juice.

Moderate

ribociclib food

Applies to: ribociclib

GENERALLY AVOID: Pomegranates and grapefruit may increase the systemic exposure to ribociclib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in these fruits. Increased exposure to ribociclib may increase the risk of adverse effects such as infections, neutropenia, leukopenia, anemia, thrombocytopenia, anorexia, nausea, vomiting, diarrhea, stomatitis, alopecia, fatigue, headache, and abnormal liver function may be increased.

MANAGEMENT: Patients receiving ribociclib should avoid consumption of pomegranates or pomegranate juice and grapefruit or grapefruit juice during treatment.

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.
