Levetiracetam is an antiepileptic medication indicated for the treatment of partial-onset seizures in patients one month of age and older.

How LEVETIRACETAM Works

The precise mechanism by which levetiracetam exerts its antiepileptic effect is unknown. However, it is known to bind to the synaptic vesicle protein SV2A in neuronal tissue, which is believed to be involved in the regulation of vesicle exocytosis and neurotransmitter release. The affinity of levetiracetam for SV2A correlates with its potency in preventing seizures, suggesting that this interaction contributes to its therapeutic mechanism of action.
