Summary
Atogepant is a CYP3A4 substrate. Aprepitant inhibits CYP3A4 when given as a short course, so atogepant exposure is more likely to increase than decrease, and the legacy direction is doubtful. Higher atogepant levels may increase adverse effects such as nausea, constipation and fatigue.
What this interaction means in plain words
Aprepitant and Atogepant can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Aprepitant belongs to Gastrointestinal Tract; Atogepant belongs to Central Nervous System.
Why it happens
Aprepitant inhibits CYP3A4, reducing atogepant metabolism, although aprepitant can also induce CYP3A4 with longer exposure.
What to do
Monitor for atogepant adverse effects during aprepitant courses. Consider dose limitation of atogepant in line with labeling for CYP3A4 inhibitors.
