谷氨酸鈉注射液为一种因肝脏疾病所致脑病的对症治疗药,以往我厂生产該注射液时,事前除了控制原料純度外,每次还需通过小样試制。往往原料純度合格,小样注射液质量不好,不能投产;有时甚至小样质量很好,在大样投产时往往又发現难滤的混浊,溶液色黄,儲藏不久即变质等情况。通过研究試驗,改进了配制工艺;将原先冷配改为热配。先配成40%浓度谷氨酸鈉,pH值控制在8.2左右,黄沸15分钟(通过煑沸,原料
Sodium glutamate injection for liver disease caused by a symptomatic treatment of encephalopathy, in the past when I plant the injection, in addition to control the purity of raw materials, each also need to pass a sample trial. Often qualified purity of raw materials, sample injection quality is not good, can not put into operation; sometimes even sample quality is very good, large sample production often found difficult to filter turbidity, yellow solution, soon metamorphism and so on. Through research and testing, improved the preparation process; the original cold with heat to change. First with 40% concentration of sodium glutamate, pH control at about 8.2, yellow boiling 15 minutes (by boiling, raw materials
