Mechanism of action

These drugs typically act on ion channels or neurotransmitter systems to suppress the synchronized thalamic-cortical oscillations that underlie absence seizures. Common mechanisms include enhancement of GABAergic inhibition, modulation of T-type calcium channels, or effects on sodium channels. The goal is to prevent the 3 Hz spike-and-wave discharges seen on EEG during absence seizures.
