Drug Interaction Report

ADJUST DOSE: Coadministration with potent or moderate inducers of CYP450 3A4 may significantly decrease the plasma concentrations of atogepant, which is primarily metabolized by the isoenzyme. When atogepant was administered in healthy study subjects with steady-state rifampin, a potent CYP450 3A4 inducer, atogepant peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by approximately 30% and 60%, respectively. No dedicated drug interaction studies were conducted to assess concomitant use with moderate CYP450 3A4 inducers, but reduced atogepant exposure would be expected.

MANAGEMENT: The recommended dosage of atogepant is 30 mg or 60 mg once daily when used concomitantly with potent or moderate CYP450 3A4 inducers.
