替硝唑葡萄糖注射液与注射用头孢噻肟钠的配伍稳定性

摘要

OBJECTIVE:To evaluate the stability of tinidazole and cefotaxime sodium mixed in infusion fluid at 4℃,25℃ and 37℃ for 24 hours.METHODS:Tinidazole and cefotaxime sodium were determined by RP-HPLC method and the pH of solution was determined with a pH meter.RESULTS:There were no significant changes in pH of the solution at 4℃,25℃ and 37℃ for 24 hours; Along with the duration, there were significant changes in the appearance of solution and the concentrations of tinidazole and cefotaxime sodium.UV absorption curve of tinidazole and cefotaxime mixed solution revealed small changes at 4℃ for 6 hours, 25℃ for 2 hours and 37℃ for 1 hour, showing a new peak.CONCLUSION: Tinidazole and cefotaxime sodium mixed in infusion fluid were stable at 4℃ for 6 hours,25℃ for 2 hours and 37℃ for 1 hour.%目的：考察4℃、25℃、37℃下24h内替硝唑葡萄糖注射液与注射用头孢噻肟钠的配伍稳定性。方法：采用反相高效液相色谱法测定配伍后4℃、25℃、37℃下24h内不同时间替硝唑与头孢噻肟钠的含量，同时观察外观并测定pH值。结果：在3种温度下24h内，配伍液的pH值无明显变化；配伍液的外观、替硝唑和头孢噻肟钠的含量随时间有明显变化；在4℃6h时、25℃2h时、37℃1h时，配伍液的吸收曲线发生微小变化，产生了新的最大吸收峰位。结论：在4℃6h内、25℃2h内、37℃1h内，替硝唑葡萄糖注射液与注射用头孢噻肟钠的配伍液稳定。
