[Abstract] Objective: To prepare alginic sodium diester and sodium chloride injection,establish its quality control and investigate its stability and safety. Methods: Some work was done to optimize the prescription and preparation technology.The character, identification and examination et al were tested. The content of alginic sodium diester and sodium chloride were determined by the method of titration.Stress testing, accelerated testing and long-term testing were done to study its stability.The safety was evaluated by testing the vessel stimulation,haemolyticus and hypersensitivity. Results: The mean recovery and RSD of alginic sodium diester and sodium chloride were 99.73%,0.34% and 100.93%, 0.17% respectively.No obvious changes were observed at 6 months of an accelerated test or 12 months of long-term storage test. Conclusion: The preparation is reasonable in formulation,simple and convenient in preparation technique,accurate in quality control,good in stablility,and safe in application.

藻酸双酯钠是以海藻提取物为基础原料,经引入有效基团精制而得的多糖类化合物,属类肝素药。具有抗凝血、降低血黏度、降血脂、抑制红细胞和血小板聚集和改善微循环作用,是近年来常用的预防心脑血管疾病和改善微循环药物之一[1-5]。鉴于藻酸双酯钠安瓿装注射剂不能直接肌注和静脉注射,临用前须注入5%或10%葡萄糖注射液和0.9%氯化钠注射液内稀释后再用[6],这样配制过程中药物有可能被空气、尘埃、异物和微生物污染,故笔者研制开发了藻酸双酯钠氯化钠注射液,直接静脉滴注,可避免上述现象的产生,方便临床应用,降低护理人员工作量 ......
