[Antihypoxant and antiamnesic effects of calcium ketopantoylaminobutyrate].

Experimental investigation of calcium ketopantoylaminobutyrate (Ca-KPAB), a new drug with a structure close to that of pantogam, showed that Ca-KPAB exhibits a pronounced antihypoxant effect on the normobaric and histotoxic hypoxia models. The new drug also produced a more pronounced antiamnesic action as compared to that of pantogam. A significant decrease in the effective drug dose in the case of Ca-KPAB is explained by its ability to readily bypass the blood - brain barrier.
