Summary
Pentobarbital induces hepatic enzymes including CYP2C19 and CYP3A4 and may lower escitalopram levels. Additive CNS depression can also occur.
What this interaction means in plain words
Escitalopram and Pentobarbital 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
Enzyme induction increases escitalopram clearance, and both drugs have CNS depressant effects.
