Abstract:
Objective To investigate the content stability of polymyxin B sulfate in high concentration solution and its finished infusion,and to provide a scientific basis for clinical administration.Methods Polymyxin B sulfate was dissolved in 0.9%sodium chloride injection and 5%glucose solution to the concentrations of 0.5 mg·mL-1,1 mg·mL-1 and 5 mg·mL-1,respectively.The content of polymyxin B was determined at 0,2,4,6,8,12,16,20 and 24 h by high-performance liquid chromatography under storage conditions of 4℃and 25℃.Results Polymyxin B sulfate was stable in the concentrations of 0.5 mg·mL-1,1 mg·mL-1 and 5 mg·mL-1,respectively,in 0.9%sodium chloride injection or 5%glucose injection.Under the storage conditions of 4℃and 25℃,the content of polymyxin B1 and polymyxin B2 ranged from 97.23%to 101.26%and 97.30%to 102.63%,respectively.Conclusion Polymyxin B sulfate was stable within 24 h dissolved either in 0.9%sodium chloride injection or in 5%glucose injection with the concentrations of 0.5 mg·mL-1,1 mg·mL-1 and 5 mg·mL-1 under the storage condition of 4℃and 25℃.
