Levetiracetam

Levetiracetam (brand name: Keppra) is an anti-convulsant medication used to treat epilepsy. It is S- enantiomer of etiracetam, structurally similar to the prototypical nootropic drug piracetam (Nootropil). Along with other anticonvulsants like Gabapentin (Neurontin), it is also sometimes used to treat neuropathic pain.
