Pharmacology
Lacosamide selectively enhances slow inactivation of voltage-gated sodium channels, resulting in stabilization of hyperexcitable neuronal membranes and inhibition of repetitive neuronal firing; it is a functionalized amino acid antiepileptic agent.
Cenobamate reduces repetitive neuronal firing by inhibiting voltage-gated sodium currents and is also a positive allosteric modulator of the GABA-A ion channel; the precise mechanism by which these effects translate to seizure reduction in patients with partial-onset seizures is unknown.
