Psychopharmacological Effects Of Vinpocetine In Normal Healthy Volunteers
Notes for this study:
|Number of Subjects
In 12 healthy normal weight female volunteers between the ages of 25-40, Vinpocetine at doses of 10-40mg daily taken twice a day (half dose at 8am, half dose at 2pm) 10 and 20mg showed a trend towards decreased reaction time whereas 40mg Vinpocetine was able to significantly reduce reaction time after 2 days of supplementation; from an average of 610milliseconds (ms) in placebo, 570-580ms in 20mg and 10mg vinpocetine respectively, and 430ms in 40mg.
Despite no influence on the number of errors made, the increased reaction speed influenced the Sternberg assessment technique to note an increase in working memory related to acqusition.
