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