Mechanism of action

Levetiracetam is a pyrrolidone derivative that binds to the synaptic vesicle protein SV2A, which is involved in vesicle exocytosis and neurotransmitter release. This binding mechanism is distinct from other antiepileptic drugs and appears to stabilize neuronal membranes and reduce seizure propagation. The exact downstream effects of SV2A binding that lead to anticonvulsant activity are not fully elucidated but likely involve modulation of calcium-dependent neurotransmitter release.
