<unk>  appears to be free of drug interactions with most commonly used anticonvulsants. It may increase metabolism of lamotrigine (Lamictal), whereas phenytoin (Dilantin) and carbamazepine (CBZ, Tegretol) increase the clearance of<unk> . Concomitant use of<unk>  and digoxin may increase serum concentration of the latter. In vitro studies suggest that the main metabolite of<unk>  acts as a P-glycoprotein inhibitor, and may thus increase absorption and reduce elimination of digoxin.
