Summary
Encorafenib both inhibits and induces CYP3A4, so armodafinil exposure may change in either direction. Armodafinil may in turn lower encorafenib levels, which could reduce its antitumor activity.
What this interaction means in plain words
Armodafinil and Encorafenib 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.
Armodafinil belongs to Central Nervous System; Encorafenib belongs to Oncology.
Why it happens
Mixed CYP3A4 modulation by encorafenib, together with CYP3A4 induction by armodafinil.
What to do
Monitor for loss of efficacy of encorafenib and for armodafinil adverse effects. Consider an alternative wakefulness agent if response is poor.
