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.

Evidence gradeLow evidence

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 risk

    Little evidence it enhances cognition in healthy adults.

  • GI upset & agitation

    low risk

    Possible nausea, insomnia, or agitation.
