title: Quantitative pharmaco-EEG of carbamazepine in volunteers and epileptics.
abstract: In order to measure the effect of carbamazepine (CBZ) on quantitative EEG (qEEG), one dose of CBZ (300 mg) was administered to 10 epileptics and 10 healthy adult volunteers. EEG samples were recorded before and at regular intervals within 24 hours following administration. The EEG activity was processed by power spectral analysis and the drug serum concentration was assessed concomitantly. The results showed that with the increase of serum concentration of CBZ, the percentage of power progressively increased in the theta band while it decreased in the alpha 2 band. The percentage of theta and alpha 2 power was found to reach maximum and minimum levels, respectively, when the peak values of serum concentration of CBZ were attained. The effects on qEEG in anterior scalp areas were more evident than in posterior scalp areas.
