    • Chemical Class:

      A pyrrolidinone and carboxamide that is <element>N</element>-methylpyrrolidin-2-one in which one of the methyl hydrogens is replaced by an aminocarbonyl group, while another is replaced by an ethyl gr oup (the <stereo>S</stereo> enantiomer). An anticonvulsant, it is used for the treatment of epilepsy in both human and veterinary medicine. ChEBI CHEBI:6437

    • Bio Activity:

      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 mo dels. Binds synaptic vesicle protein 2A (SV2A) and inhibits Na+-dependent Cl-/HCO3- exchange. Tocris Bioscience 2839

      Levetiracetam(UCB L059) is a novel anticonvulsant with antihyperalgesic efficacy in inflammatory pain.;Target: Calcium ChannelLevetiracetam is used to control some types of seizures in patients with epilepsy. This medicine cannot cure epilepsy and will only work to control seizures for as long as you continue to use it. The exact mechanism for levetiracetam is unknown. However, the drug binds to a synaptic vesicle protein, SV2A, which is believed to impede nerve conduction across synapses [1].Levetiracetam (10-200 mg/kg), ibuprofen (12.5-100 mg/kg), celecoxib (3.75-30 mg/kg), paracetamol (50-200 mg/kg), caffeine (15-100 mg/kg), and 2-drug combinations of levetiracetam with analgesics/caffeine produced a significant, dose-dependent reduction of inflammatory hyperalgesia. Isobolographic analysis revealed that levetiracetam exerts a synergistic interaction with analgesics, with approximately 7-, 9-, and 11-fold reduction of doses of both drugs in combination of levetiracetam with pa MedChem Express HY-B0106
