[Spectral-analytical studies of the action of etifoxin on the human EEG]

Spectral analysis of EEG in healthy volunteers shows that Etifoxin, the hydrochloride of 6-chloro-4-methyl-4-phenyl-2-ethylamino-4H-3,1-benzoxazine (Hoe 36,801), in an oral dosage of 100 mg has a differential effect in function of the individual alpha organization. This differential effect appearing in the course of the quantitative evaluation can be interpreted, from a morphological point of view, as an expression of various partial phases and patterns of a process leading to reduced vigilance.
