Quick Take

Skip unless you are in a clinical trial—evidence in healthy adults is too weak to justify use.

Oxiracetam is a synthetic racetam compound developed in the 1970s and investigated primarily as a prescription drug for cognitive impairment in Europe. It is chemically related to piracetam but is claimed to have slightly more stimulatory properties. Human research consists mainly of small, older randomized trials in elderly patients with dementia or organic brain syndrome, where it has shown modest improvements on memory and attention scales compared with placebo. There is very little controlled research in cognitively healthy adults, and no convincing evidence that it enhances cognition in t

Participants in formal nootropic research studies

How It Works

Oxiracetam appears to modulate acetylcholine and glutamate neurotransmission, particularly interacting with AMPA-sensitive glutamate receptors (ampakine-like activity). It may increase high-affinity choline uptake and cerebral phospholipid metabolism, though most mechanistic work is preclinical.
