[Dissociation of the anti-amnesic and antihypoxic effects of nootropic and antihypoxic preparations].

In experimental studies on mice it was shown that piracetam, Cleregil, centrophenoxine, pyritinol possessed the most pronounced anti-amnestic activity. A close effect was noted with Euclidan, 3-hydroxypyridine and ionol. GABAergic agents (sodium oxybutyrate, phenibut, pantogam), gutimine, nicotinoyl-GABA eliminated amnesia to a lesser extent. The antihypoxic effect on the model of hypobaric hypoxia was exerted by typical antihypoxic agents (gutimine, sodium oxybutyrate, 3-hydroxypyridine). The antihypoxic activity of nootropic drugs (centrophenoxine, pyritinol, phenibut) could be determined only at a significant increase of doses. No interrelationship and the presence of dissociation in manifestation of anti-amnestic and antihypoxic effects were revealed.
