Vimpat (Lacosamide) — Anticonvulsant (sodium channel modulator)
Verdict at Tovani Health
Fully compatible with KAP.
Lacosamide and ketamine have no clinically significant interaction. Lacosamide is cleaner than older anticonvulsants on cognitive side effects and CYP interactions. Modest PR interval prolongation (not QT) is the medication's main cardiac signal and is independent of KAP.
