Описание
Carbamazepine reduces topiramate plasma concentrations by approximately 40% through enzyme induction, potentially impairing seizure control.
Механизм
Carbamazepine induces CYP3A4, which contributes to topiramate metabolism; increased topiramate clearance reduces its plasma levels.
Клиническое значение
Seizure breakthrough is a risk when this combination is used; topiramate dose adjustment is typically required.
Тактика ведения
Monitor seizure frequency and topiramate levels; consider dose titration upward when carbamazepine is co-prescribed.
