Observation of the Stability of Mezlocillin Sodium in Infusion Fluids Using Orthogonal Test / 中国药房

ABSTRACT

OBJECTIVE： To observe the stability of mezlocillin sodium in 5％ glucose injection， glucose and sodium chloride injection and maintain solution for infants injection with different pH， over different periods and at 4℃ ， 25℃ ， 37℃ .METHODS： 9 solutions with different pH were made up by mezlocillin sodium and above-mentioned infusion fluids， according to 4 factors and 3 levels to make L9（34） orthogonal test.Then determination of mezlocillin sodium in each solution was carried out with ultraviolet spectrophotometry.RESULTS： The contents of mezlocillin sodium in above-mentioned solutions with different pH and at different temperature have not changed obviously over 0h-8h.CONCLUSION： Mezlocillin sodium is compatible with above-mentioned solutions.
