Brivaracetam, the 4-n-propyl analog of levetiracetam, is a racetam derivative with anticonvulsant properties.[1][2] Brivaracetam is believed to act by binding to the ubiquitous synaptic vesicle protein SV2.[3] Phase II clinical trials in adult patients with refractory partial seizures were promising. Positive preliminary results from stage III trials have been recorded,[4][5] along with evidence that it is around 10 times more potent[6] for the prevention of certain types of seizure in mouse models than levetiracetam, of which it is an analogue.
