Animal · Abstract reviewedColuracetam: what does this study show?
AF64A-treated mice received oral MKC-231 at 0.3, 1 or 3 mg/kg once daily for 11 days. Acute administration and other nootropic agents were also examined.
Repeated treatment improved working-memory performance at all tested doses. Acute administration did not significantly improve memory at the tested doses. Some repeated doses reversed hippocampal acetylcholine depletion.
Limits & adverse findings: A toxin-induced mouse model does not establish a human regimen, clinical efficacy or safety. A toxin-induced mouse model does not establish a human regimen, clinical efficacy or safety.

The research below distinguishes observed findings from interpretation. [1]
- Known half-life
No source-verified value in this profile yet. A treatment schedule or duration of an effect is not a drug half-life.
Half-life describes how quickly the measured drug concentration falls by half. It does not set a dosing interval.- Evidence & important limits
A toxin-induced mouse model does not establish a human regimen, clinical efficacy or safety. [1]
Safety & evidence boundaries

These are literature filters, not claims that this compound causes each effect. A keyword match is not a confirmed adverse reaction.
Interactions, rare harms, long-term effects and reversibility require separate evidence. Do not infer they are absent when the sources here do not address them.
Identity, names & formulations
Canonical compound: Coluracetam · coluracetam
Searchable names: MKC-231
Names share a parent research page. Different esters, salts, routes and brands are not assumed to have the same half-life, indication or exposure.
Combination evidence stays attached to the studied combination. It is not automatically assigned to each ingredient.
Understand the evidence types
Read the model and design first, then the population, outcome and limitations. These categories describe evidence, not a best-compound ranking.
- Randomized human trials
- Compare assigned interventions. Randomization does not by itself establish low bias or relevance to every population.
- Controlled human studies
- Use a comparison group; allocation and confounding still matter.
- Prospective human research
- Follows participants forward. It may be observational or interventional, so this is not a separate quality grade.
- Observational human research
- Describes associations. Confounding can explain differences.
- Case reports and series
- Useful for unusual events and safety signals, not reliable rates or effect sizes.
- Animal research
- Can test biology and function in a living model. Human exposure, benefit and safety remain separate questions.
- Cell and tissue research
- Tests responses in a preparation, including human-derived cells. It is not a human participant trial.
- Mechanistic and computational evidence
- Helps explain or predict a pathway; predictions need experimental and clinical testing.
- Anecdotal reports
- Self-reported experiences can generate questions. Product identity, selection bias and other interventions may be uncontrolled.
Systematic reviews synthesize studies and depend on their quality. Preprint status and abstract versus full-paper reading are separate labels. Citation popularity measures attention, not reliability. A study summary is not a formal quality appraisal.
