目的:考察多索茶碱与倍他米松磷酸钠在0.9%氯化钠溶液中的稳定性并进行分析。方法:观察并测定多索茶碱与倍他米松磷酸钠在0.9%氯化钠溶液中配伍后室温放置6 h内的外观及pH,并采用HPLC法测定配伍液室温放置6 h内的含量变化。结果:与配伍0 h比较,配伍液放置6 h内的外观、色泽及含量均无明显变化,pH略有变化。配伍液中多索茶碱与倍他米松含量在6 h内保持在95%以上,配伍6 h内无新物质产生。结论:多索茶碱与倍他米松磷酸钠在0.9%氯化钠溶液中配伍后于室温放置6 h内性质基本稳定。
Objective: To investigate the stability of doxofylline and betamethasone sodium phosphate in 0.9% sodium chloride solution and analyze. Methods: The appearance and pH of doxofylline and betamethasone sodium phosphate in 0.9% sodium chloride solution were observed and measured within 6 h at room temperature. The content of the compatibilized solution was measured within 6 h at room temperature by HPLC . Results: Compared with 0 h compatibility, the compatibility of the solution within 6 h of appearance, color and content were no significant changes in pH slightly changed. The content of doxofylline and betamethasone in the compatibility solution remained above 95% within 6 h and no new substances were produced within 6 h of compatibility. Conclusion: The properties of doxofylline and betamethasone sodium phosphate in 0.9% sodium chloride solution are basically stable after being placed at room temperature for 6 h.
