Piracetam
Racetam (pyrrolidone derivative)
Also known as: Nootropil, Lucetam
The original 'nootropic', a racetam studied for cognition and myoclonus. Evidence for healthy cognitive enhancement is weak and inconsistent.
Some evidence in cognitive decline and myoclonus, but little support for enhancement in healthy people.
Mostly small, open-label, or observational human data.
Intended use
Used clinically (in some countries) for myoclonus and cognitive decline; used off-label for memory and learning.
Mechanism of action
Modulates neuronal membrane fluidity and AMPA/cholinergic signaling; precise mechanism remains uncertain.
Reported benefits
Myoclonus
Established adjunct treatment for cortical myoclonus.
Cognitive decline
Mixed evidence for benefit in dementia/age-related decline.
Well tolerated
Generally low toxicity and mild side-effect profile.
Risks & side effects
Limited healthy-user benefit
low riskLittle evidence it enhances cognition in healthy adults.
GI upset & agitation
low riskPossible nausea, insomnia, or agitation.
