§ 04 — SCIENCE

Clinical trials demonstrate that pramiracetam partially reversed scopolamine-induced amnesia in healthy volunteers across age groups. A placebo-controlled study in head injury patients showed clinically significant improvements in delayed recall and memory measures, maintained over an 18-month open-trial period. Animal studies found enhanced reference memory in radial maze tasks at 7.5 and 15 mg/kg doses. However, a trial in Alzheimer's disease patients found doses up to 4,000 mg unlikely to confer symptomatic benefit, with an inverted U-shaped dose-response curve. Pharmacokinetic data show linear dose-proportional plasma concentrations with peak at 2-3 hours and elimination half-life of 4.5-6.5 hours. Evidence for cognitive enhancement in healthy non-impaired individuals remains limited and largely anecdotal.
