Biochem/physiol Actions Levetiracetam is a pyrrolidine with antiepileptic activity. Stereoselective binding of levetiracetam was confined to synaptic plasma membranes in the central nervous system with no binding occurring in peripheral tissue. Levetiracetam inhibits burst firing without affecting normal neuronal excitability, which suggests that it may selectively prevent hyper-synchronization of epileptiform burst firing and propagation of seizure activity. 法律信息 Keppra 注册商标 UCB Pharma, S.A.
