摘要
目的:考察注射用头孢拉定与奥硝唑氯化钠注射液的配伍稳定性。方法:采用高效液相色谱法,以Nova-pakC18为色谱柱,甲醇-水(35∶65)为流动相,240nm为检测波长,测定注射用头孢拉定与奥硝唑氯化钠注射液配伍后在室温下8h内的含量变化,并观察和检测配伍液的外观及pH值变化。结果:配伍液外观、pH值及含量均无明显变化。结论:注射用头孢拉定与奥硝唑氯化钠注射液配伍后在室温下8h内可使用。
OBJECTIVE:To study the stability of the mixture of cefradine for injection and ornidazole sodium chloride injection.METHODS:HPLC method was adopted in which the Nova-pak C 18 was taken as the chromatographic column,methanol-water(35∶65)was taken as the mobile phase with detection wavelength at240nm.The contents were determined after mixing of cefradine for injection and ornidazole sodium chloride injection under the room temperature within8hours,and the appearance of the solution was observed and its pH value was determined.RESULTS:No significant differences were found in terms of the appearance,pH value and the contents of the mixed solution.CONCLUSION:The mixture of ornidazole for injection and cefradine sodium chloride injection can be used under room temperature within8hours of mixing.
