Pramiracetam, a memory drug approved in parts of Europe, unapproved in the United States, is used to protect or sharpen memory. Small, old studies point toward better memory after brain injury or age-related memory complaints, not in Alzheimer's disease. No trial has tested enhancement in healthy people at usual doses; nothing links it to longer life. Side effects appear mostly mild; with grey-market products, quality may be the larger risk.

| Marker | Target | Why |
|---|---|---|
| Serum creatinine with eGFR | Men 0.74–1.35 mg/dL; women 0.59–1.04 mg/dL | Safety: kidney clearance governs exposure |
| Delayed word-list recall score | No established target; track change from own baseline | Main improved measure |
| Pregnancy test (women of reproductive potential) | Negative | Safety: pregnancy contraindicates use |
Cadence: Baseline before starting (memory test twice); memory retest at 4 and 8 weeks, then every 6 months; kidney function at 8 weeks, then every 6–12 months, or sooner when kidney-affecting drugs are started
