Establishment and validation of sterility test of levofloxacin lactate and sodium chloride injection / 药学实践杂志

ABSTRACT

Objective To establish a sterility test of levofloxacin lactate and sodium chloride injection .Methods The test was carried out by thin-membrane filtration method with different volume of flushing liquid or adding neutralization into culture medium according to the Appendix of Chinese Pharmacopoeia (2010 edition) .Results When 0 .1% peptone water was used as flushing liquid ,Staphylococcus aureus gave no evidence of growth until the amount of flushing liquid reached 700 ml per tube (100 ml each time) .At the same time ,all of the six positive control bacteria grew normally when there was 300 ml flushing liquid in each tube with neutralization as culture medium .Conclusion This method was simple and convenient ,suggesting that it was suitable for the sterility test of levofloxacin lactate and sodium chloride injection .
