<p>Levetiracetam is a modulates the activity of the synaptic vesicle protein 2A (SV2A) in the brain and is used to treat epilepsy.It is not clear exactly how Levetiracetam affects the activity of SV2A and if this is through inhibiting the release of neurotransmitters. However, it is thought to work by binding to a specific site on SV2A, which interferes with its normal function and ultimately leads to changes in exocytosis. One of the postulated mechanisms of action is that this modulates glutamate release.
