其他信息

用途二:早期用材林于抗眩晕和止吐药，目前作为神经系统药物，有促进和增强大脑记乙功能的作用，对老年性记忆减退有效。对某些低智能儿的智力提高胶，对老年性痴呆、脑外伤引起的记忆和思维障碍亦有一定疗效。
下游产品:左乙拉西坦
中枢神经兴奋药:吡拉西坦又称脑复康、吡乙酰胺、乙酰胺吡咯环酮，是一种脑代谢改善药物，属于γ-氨基丁酸的环化衍生物，对中枢作用选择性强，仅限于脑功能(记忆、意识等)的改善，精神兴奋作用弱，无精神药物的副作用，无依赖性。可预防或保护动物因缺氧而导致的逆行性健忘，亦能明显拮抗巴比妥盐对中枢的抑制作用，能促进脑细胞代谢，增加大脑对氨基酸、蛋白质、葡萄糖的吸收和利用，具有激活、保护和修复大脑神经细胞的作用，能促使脑内ADP转化为ATP，改善脑内代谢能量供应状况。它影响胆碱能神经元兴奋传递，促进乙酰胆碱合成。吡拉西坦可以抵抗物理因素和化学因素所致的脑功能损害，改善学习、记忆和回忆能力。可以改善由缺氧所造成的逆行性遗忘。口服易吸收，30～40分钟后血药浓度达峰值，蛋白结合率为30%，清除半衰期4～6小时，易透过血脑屏障，到达脑和脑脊液。口服后不能由肝脏分解，以原形形式从尿和粪便中排泄。主要用于脑部疾病所致的记忆和思维障碍，儿童器质性痴呆和智力低下，对轻中度的老年性痴呆有一定的作用，但对重症者无效。对改善功能性大脑功能衰退症候群的症状也有一定的疗效。吡拉西坦也可用于脑炎、一氧化碳、农药及酒精中毒的意识恢复，可用静注或滴注。
