TITLE:
摘要: 目的:考察硫酸头孢匹罗与奥硝唑的配伍稳定性。方法:在室温[(20±1) ℃]下,观察注射用硫酸头孢匹罗与注射用奥硝唑在0.9%氯化钠注射液和5%葡萄糖注射液中配伍0、1、2、4、6 h后的外观(颜色、澄清度、沉淀与气体)、pH值变化,采用反相高效液相色谱法测定两药配伍后的含量变化。结果:两药配伍后6 h内外观无明显变化,pH值在3.359~3.588之间; 与配伍初时(0 h)比较,各时间点硫酸头孢匹罗、奥硝唑在0.9%氯化钠注射液中的含量在100.2%~100.3%、99.9%~100.4%之间,在5%葡萄糖注射液中的含量在99.7%~99.9%、99.4%~99.6%之间。结论:室温条件下,6 h内硫酸头孢匹罗与奥硝唑在0.9%氯化钠注射液和5%葡萄糖注射液中配伍后的外观、pH值与含量稳定。
ABSTRACT: OBJECTIVE: To investigate the compatible stability of cefpirome sulfate with ornidazole. METHODS: At room temperature [(20±1) ℃], the appearances (color, clarity, sedimentation and gas) and pH changes of the mixtures by Cefpirome sulfate for injection with Ornidazole for injection in 0.9% Sodium chloride injection and 5% Glucose injection after 0, 1, 2, 4, 6 h were observed. RP-HPLC was adopted to determine its content changes. RESULTS: No significant change was noted for the mixture in appearance within 6 h, pH value ranged in 3.359-3.588; compared with the beginning (0 h), the contents of cefpirome sulfate and ornidazole ranged in 100.2%-100.3%, 99.9%-100.4% in 0.9% Sodium chloride injection at each time point, as well as 99.7%-99.9%, 99.4%-99.6% in 5% Glucose injection. CONCLUSIONS: At room temperature, cefpirome sulfate mixed with ornidazole show stable appearance, pH value and content in 0.9% Sodium chloride injection and 5% Glucose injection within 6 h.
