头孢拉啶临床上多采用静脉给药，但其水溶液不稳定，一般文献记载头孢拉定（头孢拉啶和L－精氨酸混合物）在10％葡萄糖输液中室温下稳定期为3.14h（1）。本文采用恒温加速试验法进行预测，用紫外分光光度法在262±1nm波长处测定头孢拉定的相对百分含量，预测头孢拉啶（头孢拉啶和碳酸钠混合物）10％葡萄糖溶液的稳定性及不同pH下的影响。
Cefradine is clinically used intravenously, but its aqueous solution is not stable. Cefradine (a mixture of cefradine and L-arginine) is generally documented to have a stationary phase of 3.14 h (1) at room temperature in a 10% glucose infusion. In this paper, the thermostatic accelerated test was used to predict the relative percentage of cephradine by UV spectrophotometry at a wavelength of 262 ± 1 nm. The stability and the difference of cephradine (a mixture of cephradine and sodium carbonate) of 10% glucose solution were predicted Effect at pH.
