Abstract

Nootropic properties of ACTH4‐10 analogue, Semax, were demonstrated in experiments with human volunteers. The antihypoxic effect of Semax was shown by EEG analysis after short‐term hyperventilation. Semax induced changes in the EEG similar to those seen after administration of typical nootropic drugs. Particularly important was the long‐term (20‐24 h) beneficial action of Semax on the work efficiency of operators after intranasal administration of 0.25− 1.0 mg of the peptide (about 4.0 − 16.0 μg/kg body weight).
