The invention provides a double auxiliary injection with levo oxiracetam freeze-dried powder injection, relates to the field of medicine preparation and preparation method, mainly solving the existing freeze prior levo oxiracetam injection powder injection production excipients in the production of freeze-dried time, drying temperature is high, the disadvantage of large energy consumption. With the freeze dried powder injection of levo oxiracetam using double accessories, accessories including mannitol and hydroxyethyl starch 130/0.4, the main drug is levo oxiracetam, excipient of the weight ratio of 100:90 80:110, mannitol and hydroxyethyl starch 130/0.4 weight ratio of 100:100 100: 120. The main drug and the excipients prepared into freeze dried powder injection with levo oxiracetam. Frozen with levo oxiracetam injection of the present invention powder injection is safe and effective, product quality is stable, simple production process, the production of frozen dry in a short time, low energy consumption, low temperature drying.
【技术实现步骤摘要】
一种双辅料注射用左旋奥拉西坦冻干粉针剂
:本专利技术涉及医药制剂及制备方法领域,尤其涉及一种双辅料的注射用左旋奥拉西坦冻干粉针剂及其制备方法。
技术介绍
:注射用左旋奥拉西坦冻干粉针剂主药左旋奥拉西坦是奥拉西坦的S构型,且左旋奥拉西坦的溶解性明显优于消旋体。奥拉西坦为环GABOB衍生物。动物实验证实奥拉西坦对化学物质所致学习记忆障碍有显著改善作用和促进学习记忆作用。奥拉西坦为一种促智药,临床主要用于轻中度血管性痴呆、阿尔茨海默病(老年性痴呆)以及脑外伤等症引起的记忆与智能障碍。目前工业上生产注射用左旋奥拉西坦冻干粉针剂时用到的辅料分为以下几类:(1)多元醇类,如甘油、山梨醇、甘露醇、肌醇、侧金盏花醇、乙二醇、聚乙二醇等;(2)糖类,如右旋糖苷(葡聚糖)、14一环糊精、麦芽糊精、海藻糖、蔗糖、乳糖、麦芽糖、葡萄糖等;(3)氨基酸类,如谷氨酸钠、脯氨酸、赖氨酸和丙氨酸等;(4)无机盐类,如磷酸盐、碳酸钙、硫酸锰、乙酸钠等;(5)蛋白质及肽类,如粘多糖蛋白、酪蛋白、牛血清蛋白等。羟乙基淀粉130/0.4是对人体无毒无害的半合成大分子化合物,无药理活性,在医疗上大剂量使用 ...
