What this interaction means in plain words

Armodafinil and Sufentanil 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; Sufentanil belongs to Musculoskeletal.

Why it happens
