Objective To establish a sterility test method for thymopentin for injection (TP-5).Methods The membrane filtration method was adopted according to the provision of sterility test method in Chinese Pharmacopoeia(Edition 2010,Vol Ⅱ) ,doing methodology validation with different flushing dose,to make sure the optimal flushing dose for eliminate bacteriostasis components.Results The optimal flushing dose for eliminate bacteriostasis component was 600 ml through the verification test of 60 bottles*1 mg TP-5 for injection.Conclusion The TP-5 sterility test of using membrane filtration method is feasible and effective.
Objective To establish a method for the determination of bacterial endotoxin of lansoprazole for injection through interference test of lansoprazole for injection. Methods According to method of determination of bacterial endotoxin approved by Chinese Pharmacopoeia (Edition 2010,Vol Ⅱ) . Results The interference on the determination of bacterial endotoxin can be excluded when Lansoprazole for injection was diluted the concentration of 50μg/ml. Conclusion It is feasible to detect the bacteria endotoxin of lansoprazole for injection by the method of determination of tachypleus amebocyte lysate.
