Summary
Buprenorphine causes sedation and respiratory depression, and armodafinil does not reverse these effects. Armodafinil may mask drowsiness, leading to underrecognition of excess opioid effect. Armodafinil may also weakly induce CYP3A4 and lower buprenorphine levels.
What this interaction means in plain words
Armodafinil and Buprenorphine buccal 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.
Why it happens
Opposing pharmacodynamic effects on arousal, plus weak CYP3A4 induction by armodafinil.
What to do
Monitor respiratory status and opioid withdrawal or pain control. Adjust buprenorphine dose if response changes.
