Biological Activity for Levetiracetam

Levetiracetam is an antiepileptic that displays distinctive properties from conventional antiepileptic drugs. Displays potent seizure protection in animal models of chronic epilepsy but lacks activity in acute seizure models. Binds synaptic vesicle protein 2A (SV2A) and inhibits Na+-dependent Cl-/HCO3- exchange. In a mouse model of Alzheimer's disease, Levetiracetam rescues levels of presynaptic vesicle fusion and neurotransmitter release, reduces Aβ42 and APP levels and decreases deposits of amyloid plaque; in vitro Levetiracetam inhibits Aβ-induced glutamate from astrocytes.
