Mechanism of action

Levetiracetam binds to the synaptic vesicle glycoprotein 2A (SV2A) in the brain, which modulates neurotransmitter release and reduces abnormal neuronal firing. This mechanism differs from classical anticonvulsants and helps prevent seizure initiation and spread. The exact downstream effects of SV2A binding that lead to seizure suppression are not fully elucidated but appear to involve modulation of calcium channels and synaptic plasticity.
