Mechanism of action

Antiepileptic drugs (AEDs) comprise a diverse class with heterogeneous mechanisms of action. Common mechanisms include inhibition of voltage-gated sodium channels (phenytoin, carbamazepine, lamotrigine), enhancement of GABAergic inhibition (benzodiazepines, barbiturates, valproate), modulation of T-type and L-type calcium channels (ethosuximide, gabapentin), and other mechanisms such as SV2A binding (levetiracetam) or carbonic anhydrase inhibition (topiramate). These mechanisms collectively reduce seizure threshold and neuronal firing.
