Summary
Primidone is metabolized to phenobarbital and acts as an enzyme inducer, which may lower doxorubicin exposure and weaken its effect. The clinical impact is not well quantified.
What this interaction means in plain words
Liposomal doxorubicin and Primidone 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.
Liposomal doxorubicin belongs to Oncology; Primidone belongs to Central Nervous System.
Why it happens
Induction of hepatic enzymes by primidone and its phenobarbital metabolite increases doxorubicin clearance.
