Visse antiepileptika (som phenytoin, carbamazepin, phenobarbital og primidon), der inducerer lægemiddelmetaboliserende leverenzymer, inducerer glukuronideringen og forstærker således metaboliseringen af lamotrigin.
Certain AEDs (such as phenytoin, carbamazepine, phenobarbitone and primidone) which induce hepatic drug-metabolising enzymes induce the glucuronidation of lamotrigine and enhance the metabolism of lamotrigine.
