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.
低氧性（将小鼠置于密封舱内，在箭毒化的猫身上关闭人工呼吸装置）、循环性（结扎大鼠双侧颈动脉）和组织中毒性（给猫静脉注射氰化钠）。该药物对注射亚硝酸钠诱导的血液性缺氧的猫、大鼠和小鼠没有保护作用。
