Summary

Pentobarbital induces CYP3A4 and can lower lovastatin plasma concentrations. This may reduce lipid-lowering efficacy.

What this interaction means in plain words

Lovastatin 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.

Evidence level: Low

Why it happens

Barbiturate induction of hepatic and intestinal CYP3A4 increases lovastatin clearance.

What to do

Monitor lipid profile and increase the statin dose or switch to a statin not metabolized by CYP3A4 if control is inadequate.
