Evaluation of encephalotropic and psychotropic properties of gabapentin in man by pharmaco-EEG and psychometry.
In a double-blind , placebo-controlled study the encephalotropic and psychotropic properties of gabapentin - a new gaba-analogue with anticonvulsant and antispastic properties penetrating the blood brain barrier easily - were studied in 10 normal subjects by means of quantitative pharmaco-EEG and psychometric analyses . They received r and omized and in weekly intervals single oral doses of 50 mg , 100 mg , 200 mg and 400 mg gabapentin as well as placebo .  EEG recordings and evaluation of pulse , blood pressure and side effects were carried out after 0 , 1 , 2 , 4 , 6 and 8 hours ; psychometric tests were done at the same times except for the first hour . Computer-assisted spectral analysis of the EEG showed moderate though significant central effects of gabapentine in doses of 200 - 400 mg as compared with placebo , which were maximally pronounced in the 2nd hour post drug . These alterations were generally characterized by an attenuation of total power , augmentation of delta and theta activity and a decrease of alpha activity indicating CNS-inhibitory properties . Only at the late hours did the type of changes shift towards a vigilance-promoting one . Beta activity showed alternating changes . Psychometric and psychophysiological evaluations demonstrated subtle psychotropic effects as compared with placebo characterized mostly by an improvement in concentration , numerical memory , complex reaction and performance in the alphabetical reaction test while performance variability increased as well . Subjectively experienced well-being changed dose-dependently . CFF decreased after 100 mg as did pupil size after 50 - 200 mg . Evaluation of pulse , blood pressure and side effects demonstrated good tolerability of the drug
