    【Abstract】 Objective To observe the stabilities of glucose and sodium chloride potassium injection(GNK)mixing with metronidazole and tinidazole at 25℃.Methods RP-HPLC was applied to determine the content changing of metronidazole and tinidazole in different time.The pH,quantity of non-soluble particulate and appearance of mixtures were also observed.ResultsIn room temperature the mixtures produced neither gas nor sediment.The pH,quantity of non-soluble particulate and content did not change within 8 hours.ConclusionThe mixtures of GNK mixing with metronidazole and tinidazole were stable in 8 hours. ......
