Interactions between your drugs

Moderate

nebivolol alectinib

Applies to: nebivolol and alectinib

MONITOR: Coadministration of alectinib with other agents that can slow the heart rate may increase the risk of bradycardia. In clinical trials, 7.5% of patients developed bradycardia during treatment with alectinib. Twenty percent of 221 patients for whom serial electrocardiograms were available had heart rates of less than 50 beats per minute (bpm).

MANAGEMENT: Caution is advised when alectinib is prescribed with other drugs that can cause bradycardia (e.g., beta-blockers; calcium channel blockers; digitalis; dolasetron; flecainide; ivabradine; lacosamide; mefloquine; moricizine; propafenone; quinine; succinylcholine; sunitinib; thalidomide; anticholinesterase or cholinergic agents; protease inhibitors such as atazanavir, lopinavir/ritonavir, and saquinavir/ritonavir). Heart rate and blood pressure should be monitored regularly, and patients should be counseled to seek medical attention if they experience dizziness, lightheadedness, fainting, or irregular heartbeat. Dosage modification of alectinib is not required in cases of asymptomatic bradycardia. However, if symptomatic bradycardia occurs, the manufacturer recommends withholding alectinib until recovery to asymptomatic bradycardia or to a heart rate of >=60 bpm. Evaluate concomitant medications known to cause bradycardia and all antihypertensive medications, then consider dosage adjustments or discontinuation of concomitant medication(s) or alectinib in accordance with the product labeling.

Drug and food interactions

Moderate

alectinib food

Applies to: alectinib

ADJUST DOSING INTERVAL: Food significantly enhances the oral bioavailability of alectinib and its major active metabolite, M4. According to the manufacturer, a high-fat, high-calorie meal increased the combined systemic exposure (AUC) of alectinib and M4 by 3.1-fold following oral administration of a single 600 mg dose of alectinib.

MANAGEMENT: To ensure maximal oral absorption, alectinib 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.
