The invention provides a double accessories Aceglutamide for Injection freeze-dried powder injection, relates to the field of medicine preparation and preparation method, which mainly solves the problems of the prior art in Aceglutamide for Injection freeze-dried powder production excipients production when the drying time is long, high drying temperature, the disadvantage of large energy consumption. The Aceglutamide for Injection freeze-dried powder using double accessories, accessories including mannitol and hydroxyethyl starch 130/0.4, the main drug is Acetylglutamide, excipient in the weight ratio of 100:50 80:60, mannitol and hydroxyethyl starch 130/0.4 weight ratio of 100:80 100:100. The Aceglutamide for Injection freeze-dried powder was prepared with the main drugs and the excipients. The Aceglutamide for Injection freeze-dried powder injection has the advantages of stable quality, safety and effectiveness, simple production process, short production time, low drying temperature and low energy consumption.
【技术实现步骤摘要】
一种双辅料注射用乙酰谷酰胺冻干粉针剂
: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乙酰谷酰胺冻干粉针剂及其制备方法。
技术介绍
:注射用乙酰谷酰胺冻干粉针剂主药乙酰谷酰胺为谷氨酰胺的乙酰化合物,通过血-脑脊液屏障后分解为谷氨酸γ氨基丁酸(GABA)。谷氨酸参与中枢神经系统的信息传递。γ氨基丁酸能拮抗谷氨酸兴奋性毒理作用,可改善神经细胞代谢,维持神经应激能力及降低血氨的作用,改善脑功能。本品主要用于促进神经外科手术后昏迷病人苏醒(如脑肿瘤、颅脑外伤、脑血管疾病等)。脑外伤.肝昏迷,偏瘫、高位截瘫、脑神经瘤、神经性头痛、腰痛的治疗。智力减退、记忆力障碍、小儿麻痹后遗症,血防846等药物引起的精神障碍后遗症各种原因(如一氧化碳中毒、急性酒精及药物中毒、急性化脓性脑膜炎、病毒性脑炎、肝性脑病、肺性脑病、电击伤后等)所致的昏迷、记忆与思维障碍。老年记忆力减退及脑血管病后的记忆力减退。老年脑功能衰退的辅助治疗。慢性精神病.老年性精神障碍综合症,精神忧郁症等。目前工业上生产注射用乙酰谷酰胺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、 ...
