Racetams, also sometimes known simply as pyrrolidones,[1] are a class of drugs that share a pyrrolidone nucleus.[2][3][4] Many, but not all, specifically have a 2-oxo-1-pyrrolidine acetamide (piracetam) nucleus. Some racetams, such as piracetam, aniracetam, oxiracetam, pramiracetam, and phenylpiracetam, are considered nootropics.[5] Phenylpiracetam is also a stimulant.[2] Others, such as levetiracetam, brivaracetam, and seletracetam, are anticonvulsants.[6]
