Compatible Stability of Cefoselis Sulsate with Metronidazole Injection

OBJECTIVE To study the compatible stability of cefoselis sulsate with metronidazole injection. METHODS The content of the mixture of cefoselis sulsate and metronidazole within 8 h were determined by HPLC, meanwhile the changes in appearances and the pH values were observed. RESULTS The content of cefoselis sulsate and metronidazole injection was stable within 8 h. The mixture was clear, pH value was also stable. CONCLUSION Cefoselis sulsate can be mixed with metronidazole injection for clinical use.
