<prompt> Mechanism of action of Levetiracetam are all exceptUsed in myoclonic epilepsyActs on GABA receptorsInhibits post synaptic calcium channelsBinds to SV2A and regulates exocytosis of neurotransmitter  <response>: C Inhibits post synaptic calcium channels Mechanism of Action: Inhibits a specific high-voltage activated calcium channel, the N-type Inhibit the release of calcium from intracellular stores. Oppose the inhibitory action of zinc and beta-carbolines on GABA- and glycine-gated currents. Inhibits burst firing without affecting normal neuronal excitability. Hypersynchronization of epileptiform activity is inhibited, and its distinguished Levetiracetam from other AEDs. Saturable and reversible stereoselective binding site specific for levetiracetam in CNS, SV2A. Exact mechanism by which levetiracetam acts to treat epilepsy is unknown However, the drug binds to a synaptic vesicle glycoprotein, SV2A, and inhibits presynaptic calcium channels reducing neurotransmitter release and acting as a neuromodulator. Levetiracetam: Binds to a synaptic vesicle glycoprotein involved in the regulation of vesicle exocytosis, SV2A, inhibits presynaptic calcium channels reducing neurotransmitter release acts as a neuromodulator. Levetiracetam is an anticonvulsant used to treat epilepsy. Levetiracetam may selectively prevent hypersynchronization of epileptiform burst firing and propagation of seizure activity.
