Levetiracetam

Levetiracetam is a pyrrolidone derivative. Levetiracetam binds with high affinity to synaptic vesicle protein 2A located at presynaptic nerve terminals, an important vesicle membrane protein involved in regulating neurotransmitter release. By modulating vesicle fusion and release processes, levetiracetam reduces excessive synchronized neuronal firing, especially under pathological hyperexcitable conditions, while having relatively little effect on normal neurotransmission. Through stabilization of neural network activity, it reduces neuronal hyperexcitability and abnormal discharges, thereby lowering the occurrence of epileptiform activity.
