Interactions between your drugs

Moderate

lapatinib nintedanib

Applies to: lapatinib and nintedanib

MONITOR: Coadministration with inhibitors of P-glycoprotein (P-gp) and CYP450 3A4 may increase the plasma concentrations of nintedanib, which is a substrate of the efflux transporter and a minor substrate of the isoenzyme. In a dedicated drug interaction study, administration of nintedanib with the potent P-gp and CYP450 3A4 inhibitor, ketoconazole, increased nintedanib peak plasma concentration (Cmax) by 83% and systemic exposure (AUC) by 61%. No data are available for use with other, less potent inhibitors.

MANAGEMENT: Caution is advised if nintedanib is prescribed in combination with P-gp and CYP450 3A4 inhibitors. Pharmacologic response to nintedanib should be monitored more closely whenever a CYP450 3A4/P-gp inhibitor is added to or withdrawn from therapy, and the nintedanib dosing adjusted or interrupted as necessary in accordance with the product labeling. Patients should be closely monitored for increased adverse effects such as liver enzyme and bilirubin elevations, diarrhea, nausea, vomiting, gastrointestinal perforation, bleeding, and arterial thromboembolic events (e.g., myocardial infarction).

Drug and food interactions

Moderate

lapatinib food

Applies to: lapatinib

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

ADJUST DOSING INTERVAL: Food can significantly increase the oral bioavailability of lapatinib. According to the manufacturer, lapatinib peak plasma concentration (Cmax) was approximately 2.5- and 3-fold higher and systemic exposure (AUC) 3- and 4-fold higher when administered with a low fat meal (5% fat; 500 calories) or with a high-fat meal (50% fat; 1000 calories), respectively, compared to fasting. Dividing the daily dose also resulted in an approximately 2-fold higher systemic exposure at steady state compared to the same total dose administered once daily.

MANAGEMENT: Patients treated with lapatinib should preferably avoid the consumption of grapefruit or grapefruit juice. The manufacturer recommends that lapatinib be administered at least one hour before or one hour after a meal. The lapatinib dose is administered once daily and should not be divided.

nintedanib food

Applies to: nintedanib

ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of nintedanib. After food intake, nintedanib exposure increased by approximately 20% compared to administration under fasted conditions. Absorption was also delayed, as indicated by an increase in the median time to reach maximum plasma concentration (Tmax) from 2 hours in the fasted state to approximately 4 hours under fed conditions, irrespective of the type of food ingested.

MANAGEMENT: Nintedanib should be administered with 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.
