Stability of Cefoxitin Sodium for Injection Compatible with Metronidazole Injection Fluid / 中国药房

ABSTRACT

OBJECTIVE:To evaluate the stability of cefoxitin sodium for injection compatible with metronidazole injection fluid.METHODS:Cefoxitin sodium for injection was compatible with metronidazole injection fluid and the solution was stored ordinary temperature for4hours,the maximum absorption peak and absorbance of the solution were determined by UV,and the color of the solution was observed,and its pH value was determined.RESULTS:There were no significant changes in absorp-tion peak,absorbance,color and pH value of the compatible solution.CONCLUSION:Cefoxitin sodium for injection is com-patible with metronidazole injection fluid,and the compatible solution remains stable at ordinary temperature for4hours.
