Vinpocetine effects on cognitive impairments produced by flunitrazepam.

The effects of pre-treatment with vinpocetine 40 mg, on flunitrazepam-induced impairment of memory, were studied in 8 normal volunteers. Tests of Critical Flicker Fusion Threshold, a Sternberg Memory Scanning Task, along with subjective ratings of drug action were used. Drug effects were found to be modest. Treatment with vinpocetine was associated with improvements in short-term memory processes.
