【摘要】:目的考察注射用头孢匹林钠在使用过程中分别与0.9%氯化钠注射液、5%葡萄糖注射液、10%葡萄糖注射液的配伍稳定性。方法采用高效液相色谱法,使用C18色谱柱(SB-C18,4.6mm×250mm,5μm);流动相为0.05mol/L磷酸二氢钾溶液(用10%磷酸溶液调节p H值至2.6)-乙腈(88:12);检测波长为254nm;柱温为35℃;进样量为20μL。结果注射用头孢匹林钠分别与0.9%氯化钠注射液、5%葡萄糖注射液、10%葡萄糖注射液配伍使用,在6h内溶液的外观、p H值、有关物质及含量均无明显差异;但放置24小时后,有关物质或含量均已不合格。结论建议注射用头孢匹林钠与0.9%氯化钠注射液、5%葡萄糖注射液、10%葡萄糖注射液配伍应在6h内使用完毕。
[Abstract]:Objective to investigate the compatibility stability of cefpiline sodium for injection with 0.9% sodium chloride injection, 5% glucose injection and 10% glucose injection. Methods High performance liquid chromatography (HPLC) was used with C _ (18) column SB-C186mm 脳 250mm ~ 5 渭 m ~ (-1), the mobile phase was 0.05mol/L potassium dihydrogen phosphate solution (pH value was adjusted to 2.6-acetonitrile 88: 12) with 10% phosphoric acid solution, the detection wavelength was 254 nm, the column temperature was 35 鈩,
