Racetams are a class of compounds that share a pyrrolidone nucleus. Many, including piracetam, are considered to be nootropics. Some such as oxiracetam and phenylpiracetam are also stimulants. Others such as levetiracetam and seletracetam are anticonvulsants.
Generally, racetams upregulate and preserve adequate levels of acetylcholine as a primary mechanism, suggesting they can aid recovery from deliriant intoxication and other typically cognitively impaired states.
