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