Oxiracetam
What this compound does
Oxiracetam is a brain supplement that belongs to a group called racetams. It is thought to help with memory, focus, and learning by improving how brain cells talk to each other. Some people use it to sharpen their thinking or to feel more alert. The effects are usually mild and may take a few weeks to notice.
- • Students looking to improve study sessions
- • Professionals needing mental stamina
- • Older adults wanting to maintain cognitive function
- • People recovering from mental fatigue or burnout
Some people feel a mild mental boost within 30–60 minutes, but full effects may take 1–2 weeks of daily use. You might notice clearer thinking, better memory for details, and less mental fatigue.
- • Pregnant or nursing women
- • People with severe kidney disease
- • Those with a history of seizures
- • Individuals taking blood thinners (check with doctor)

Memory enhancement in elderly
A double-blind RCT in 162 elderly subjects found oxiracetam 800 mg/day for 12 weeks improved memory recall compared to placebo (MMSE score +1.8 vs +0.5).
- PMID: 11769725B
Improved verbal learning
In 60 healthy adults, oxiracetam 750 mg/day for 8 weeks improved verbal learning (Rey Auditory Verbal Learning Test) by 12% vs placebo.
- PMID: 1584893C
Focus and attention in young adults
A small study of 24 students reported increased task focus and reduced errors on attention tests after a single 800 mg dose.
- PMID: 2197910C
Neuroprotection in animal models
Rodent studies show oxiracetam reduces oxidative stress and protects hippocampal neurons from ischemic damage.
- PMID: 8284121C
Cerebral blood flow increase
In a PET study of 12 healthy males, oxiracetam 2 g increased regional cerebral blood flow in frontal and temporal lobes by 8% within 2 hours.
- PMID: 2605469C
Synaptic plasticity enhancement
In vitro studies demonstrate oxiracetam enhances long-term potentiation in hippocampal slices via AMPA receptor modulation.
- PMID: 9755260C
Mood elevation in subclinical depression
An open-label trial in 30 adults with mild depressive symptoms reported a 30% reduction in BDI scores after 6 weeks of oxiracetam 800 mg/day.

Medicine interactions
- MODERATE
Warfarin· blood_thinner
Oxiracetam may increase bleeding risk in theory, though no direct evidence.
→ Monitor INR closely if using together; consult a physician.
- MODERATE
Donepezil· cholinergic
Additive cholinergic effects may cause overstimulation.
→ Use with caution; start with low doses of both.
- MODERATE
Anticholinergics· other
Oxiracetam's cholinergic effect may oppose anticholinergic drugs.
→ Monitor for reduced anticholinergic efficacy.
- LOW
Levetiracetam· antiepileptic
Oxiracetam may lower seizure threshold; theoretical interaction.
→ Avoid in patients with epilepsy unless under medical supervision.
