The aim was to investigate the stability of cefazolin in elastomeric infusion devices.
Elastomeric devices (Infusor LV) that contain cefazolin (3 g/240 mL and 6 g/240 mL) were prepared and stored at 4°C for 72 hours and then at 35°C for 12 hours, followed by 25°C for 12 hours. An aliquot was withdrawn at predefined time points and analyzed for the concentration of cefazolin. Samples were also assessed for changes in pH, solution color, and particle content.
Cefazolin retained acceptable chemical and physical stability over the studied storage period and conditions.
These findings will allow the administration of cefazolin by the Infusor LV elastomeric device in the outpatient and remote settings.
研究头孢唑林在弹性输注装置中的稳定性。
制备含有头孢唑林(3 g/240 mL 和 6 g/240 mL)的弹性装置(Infusor LV),并在 4°C 下储存 72 小时,然后在 35°C 下储存 12 小时,再在 25°C 下储存 12 小时。在规定的时间点抽取一份样品,并分析头孢唑林的浓度。还评估了样品的 pH 值、溶液颜色和颗粒含量的变化。
头孢唑林在研究的储存期和条件下保持了可接受的化学和物理稳定性。
这些发现将允许在门诊和远程环境中使用 Infusor LV 弹性装置给予头孢唑林。
