Drug Interaction Report

MONITOR: Coadministration of lasmiditan and agents that lower heart rate may increase the risk of bradycardia. In clinical trials, lasmiditan was associated with heart rate decreases of 5 to 10 beats per minute (bpm) while placebo was associated with decreases of 2 to 5 bpm. In a drug interaction study, a single 200 mg dose of lasmiditan led to an additional heart rate decrease of 5 bpm when given with propranolol.

MANAGEMENT: Caution is advised during coadministration of lasmiditan and agents that lower heart rate if the estimated decrease in heart rate may present a clinical risk. Consider monitoring heart rate in patients for whom the estimated decrease in heart rate may not be tolerated.

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.
