- ceritinib
- Hyftor (sirolimus topical)
Interactions between your drugs
ceritinib sirolimus topical
Applies to: ceritinib and Hyftor (sirolimus topical)
MONITOR: Sirolimus may be systemically absorbed following topical administration. Theoretically, coadministration with inhibitors of CYP450 3A4 may increase the systemic exposure of sirolimus, which is a substrate of the isoenzyme. Significant increases in systemic exposure have been reported when oral sirolimus was coadministered with potent and moderate CYP450 3A4 inhibitors such as azole antifungal agents, macrolide antibiotics, protease inhibitors, and some calcium channel blockers. No formal studies to evaluate drug interactions with topical sirolimus have been conducted.
MANAGEMENT: Caution is advised if topical sirolimus is prescribed with potent or moderate CYP450 3A4 inhibitors. Patients should be monitored for systemic sirolimus adverse effects including immunosuppression, infection, hyperlipidemia, malignancy, and interstitial lung disease.

Drug and food interactions
ceritinib food
Applies to: ceritinib
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of ceritinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Because ceritinib 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. Other, more common side effects such as diarrhea, nausea, vomiting, abdominal pain, hyperglycemia, and bradycardia may also increase.
ADJUST DOSING INTERVAL: Food increases the oral bioavailability of ceritinib. The mechanism of interaction is unknown. Compared to the fast state, administration of a single 500 mg dose of ceritinib with a high-fat meal (approximately 1000 calories; 58 grams of fat) increased ceritinib peak plasma concentration (Cmax) and systemic exposure (AUC) by 41% and 73%, respectively, and administration with a low-fat meal (approximately 330 calories; 9 grams of fat) increased ceritinib Cmax and AUC by 43% and 58%, respectively. A dose of 600 mg or higher taken with a meal is expected to produce systemic exposure exceeding that from a 750 mg dose taken in the fasted state, which may lead to increased adverse effects.
MANAGEMENT: Patients treated with ceritinib should avoid consumption of grapefruit, grapefruit juice, and any supplement containing grapefruit extract. Ceritinib should be administered on an empty stomach (i.e., avoid administration within 2 hours of a meal).
