Psychopharmacological effects of vinpocetine in normal healthy volunteers

Summary

Twelve healthy female volunteers received pre-treatments with vinpocetine 10, 20, 40 mg and placebo (t.d.s.) for two days according to a randomised, double-blind crossover design. On the third day of treatment and 1 h following morning dosage, subjects completed a battery of psychological tests including Ciritcal Flicker Fusion (CFF), Choice Reaction Time (CRT), Subjective Ratings of Drug Effects (LARS) and a Sternberg Memory Scanning Test. No statistically significant changes from placebo were observed on CFF, CRT or subjective ratings of drug effects. However, memory as assessed using the Sternberg technique was found to be significantly improved following treatment with vinpocetine 40 mg when compared to placebo and results suggested a localised effect of the drug on the serial comparison stage of the reaction process.
