Brivaracetam: A Rational Drug Discovery Success Story, Michael Rogawski Jan 2008

Brivaracetam: A Rational Drug Discovery Success Story, Michael Rogawski

Michael A. Rogawski

Levetiracetam, the alpha-ethyl analogue of the nootropic piracetam, is a widely used antiepileptic drug (AED) that provides protection against partial seizures and is also effective in the treatment of primary generalized seizure syndromes including juvenile myoclonic epilepsy. Levetiracetam was discovered in 1992 through screening in audiogenic seizure susceptible mice and, 3 years later, was reported to exhibit saturable, stereospecific binding in brain to a approximately 90 kDa protein, later identified as the ubiquitous synaptic vesicle glycoprotein SV2A. A large-scale screening effort to optimize binding affinity identified the 4-n-propyl analogue, brivaracetam, as having greater potency and a broadened spectrum of activity …

The Neurobiology Of Antiepileptic Drugs For The Treatment Of Nonepileptic Conditions, Michael A. Rogawski, Wolfgang Löscher

Michael A. Rogawski

Antiepileptic drugs (AEDs) are commonly prescribed for nonepileptic conditions, including migraine headache, chronicneuropathic pain, mood disorders, schizophrenia and various neuromuscular syndromes. In many of these conditions, as in epilepsy, the drugs act by modifying the excitability of nerve (or muscle) through effects on voltage-gated sodium and calciumchannels or by promoting inhibition mediated by γ-aminobutyric acid (GABA) A receptors. In neuropathic pain, chronic nerveinjury is associated with the redistribution and altered subunit compositions of sodium and calcium channels that predisposeneurons in sensory pathways to fire spontaneously or at inappropriately high frequencies, often from ectopic sites. AEDs maycounteract this abnormal activity by …
