Study on the Stability of Yinzhihuang Injection Mixing With Five Kinds of Infusion Fluid / 中国药房

ABSTRACT

OBJECTIVE:To study the stability of Yinzhihuang injection(YZH) mixed with 5% glucose solution,10% glucose solution,glucose in normal saline,normal saline and Ringer's solution.METHODS:After YZH mixed with infusion fluid under room temperature,the contents of baicalin were determined with UV-spectrophotometry at different time periods within 24h,the apperance was observed,the pH values of baicalin were detected and identified by TLC.RESULTS:Under room temperature,after YZH mixed with Ringer's solution,the pH value of baicalin was markedly changed and a lot of white particles appeared;after YZH mixed with GNS,no changes of pH value and content of baicalin were found within 24h.When YZH mixed with other 3 kinds of infusion fluid,there were no changes in pH value and content of baicalin within 2h,however,in mixing with NS,the number of insoluble particles produced was beyond the standard.CONCLUSION:YZH should not be mixed with NS or Ringer's solution but it is compatible with 5%GS,10%GS and GNS,however,it should be mixed with them just before use and used up within 2h.
