多索茶碱注射液与地塞米松磷酸钠注射液配伍稳定性考察

目的:考察多索茶碱注射液与地塞米松磷酸钠注射液的配伍稳定性。方法:观察及测定多索茶碱注射液与地塞米松磷酸钠注射液在5%葡萄糖注射液中配伍后于25℃放置6h内的外观及pH值,并采用高效液相色谱法测定配伍液的含量。结果:与配伍后0h比较,配伍液放置6h内的外观色泽、澄明度及含量均无明显变化,而pH值有所升高。结论:多索茶碱注射液与地塞米松磷酸钠注射液在5%葡萄糖注射液中配伍后于25℃放置6h内质量稳定。

Study on the Compatible Stability of Doxofylline Injection and Dexmethasone Sodium Phosphate Injection

OBJECTIVE:To study the compatible stability of doxofylline injection and dexmethasone sodium phosphate injection.METHODS:The changes in appearance and pH value of the mixture of doxofylline injection and dexmethasone sodium phosphate injection in 5%glucose injection within 6 hours at 25℃were observed and determined,the content of which was determined by HPLC.RESULTS:Compared with the solution at 0h of mixing,no significant changes were noted in color,clarity and content within 6 hours' mixing,however,there was an increase in its pH value.CONCLUSION:The mixture of doxophylline and dexmethasone in 5%glucose injection is stable in quality within 6 hours' mixing at 25℃.
