[Effect of piracetam on the body's resistance to hypoxia].

Piracetam increases the animals' resistance to various types of hypoxia: hypoxic (placing of mice into a sealed chamber, switch off of an artificial respiration apparatus in curarized cats), circulatory (ligation of both carotid arteries in rats), and histotoxic (intravenous injection of sodium cyanide to cats). The drug does not exert protective action in cats, rats and mice with hemic hypoxia induced by injection of sodium nitrite.
