描述
Carbamazepine reduces lamotrigine plasma concentrations by approximately 50% through enzyme induction, requiring lamotrigine dose adjustment.
机制
Carbamazepine induces UGT enzymes responsible for lamotrigine glucuronidation, accelerating its elimination and reducing plasma levels.
临床意义
Lamotrigine doses need to be doubled compared to monotherapy targets when co-prescribed with carbamazepine to maintain seizure control.
处理措施
Adjust lamotrigine dosing per manufacturer guidelines for enzyme-inducing AED co-therapy; titrate slowly and monitor seizure frequency.
