作者研究了10和50mg/ml头孢噻肟三嗪(ceftria-xone)二钠的生理盐水和5%葡萄糖溶液,在—22℃,5℃和室温(15～32℃)下的稳定性。试验用琼脂扩散法和HPLC法测定其效价。结果:用琼脂扩散法测得本品10和50mg/ml的生理盐水溶液在室温下贮存1周后的效价分别为起始时的91.0和91.5%,5%葡萄糖溶液分别为92.3和83.2%。如先经冷冻,1周后将其自然解冻, The authors studied the stability of 10 and 50 mg / ml ceftriaxone disodium salt in normal saline and 5% dextrose solution at -22 ° C, 5 ° C and room temperature (15-32 ° C). Test agar diffusion method and HPLC titer. Results: The results of agar diffusion assay showed that the titers of 10 and 50mg / ml physiological saline solution stored at room temperature for 1 week were 91.0% and 91.5%, respectively, and the 5% glucose solution was 92.3% and 83.2% . If frozen first, thaw it after 1 week,
