MONITOR: Coadministration with grapefruit products or green tea, inhibitors of CYP450 3A4, may increase the plasma concentrations of atogepant, which is primarily metabolized by the isoenzyme. When atogepant was administered with the potent CYP450 3A4 inhibitor itraconazole in healthy study subjects, atogepant peak plasma concentration (Cmax) and systemic exposure (AUC) increased by approximately 2.2- and 5.5-fold, respectively. However, moderate and weak inhibitors may interact to a much lesser extent. Population pharmacokinetic modeling has suggested that moderate (e.g., cyclosporine, ciprofloxacin, fluconazole, fluvoxamine, grapefruit juice) or weak (e.g., cimetidine, esomeprazole) CYP450 3A4 inhibitors may increase atogepant AUC by 1.7- and 1.1-fold, respectively. The changes in atogepant exposure when coadministered with moderate or weak CYP450 3A4 inhibitors are not expected to be clinically significant.

MANAGEMENT: Caution is advised for patients taking atogepant and consuming grapefruit products, large amounts of green tea beverages or green tea extract. Patients should be monitored for nausea, constipation, and fatigue.
