Study of bacterial endotoxins test in cefuroxime sodium for injection
作者: Tu, Xueqiong
The bacterial endotoxins test was performed in cefuroxime sodium injection according to Chinese Pharmacopoeia of 2000 edition.Cefuroxime sodium injection did not bring interference at the concentration of 6.68 mg/mL and the bacterial endotoxin detection limit was 0.15 EU/mg.These results suggest that the bacterial endotoxins test can be used for endotoxin detection in cefuroxime sodium injection instead of pyrogen test.
