关键药物在暴露于极度寒冷时会降解或失效,例如深或冷解周期,影响其在恶劣环境中的稳定性和有效性.
科学领域:
- 制药科学 制药科学
- 环境医学 环境医学
- 军人卫生保健 军人卫生保健
背景情况:
- 标准的药物储存和使用是在室温下进行的.
- 极端寒冷的环境,如北极任务,对药物完整性构成风险.
- 对深和冷解周期的药物耐受性在很大程度上是未知的.
研究的目的:
- 在模拟极寒条件下评估基本药物的物理和化学稳定性.
- 为了确定长时间的冷和冷-解循环对药物的疗效的影响.
- 识别不适合在寒冷环境中使用的药物.
主要方法:
- 十五种必需药物经过深 (-51°C) 和冷解 (-40°C至20°C) 周期,长达90天.
- 药物的稳定性通过视觉检查和度测试 (高性能液态染色学) 来评估.
- 根据FDA的指导方针,超过标记度的10%的变化被认为是显著的.
主要成果:
- 艾米奥达龙,上腺素,上腺素,上腺素,上腺素,德克萨米他,罗库和上腺素保持稳定.
- 普罗波乳液中断,并且在30天内发生了显著的降解.
- 碳酸,酸,化和顺胆的瓶子破碎;上腺素显示身体变化;上腺素有有限的破损.
结论:
- 某些必需药物在长时间暴露在寒冷环境下容易发生物理和化学降解.
- 不建议在极度寒冷的情况下配制,酸,上腺素,化,胆和二碳酸.
- 开发替代配方,包装和环境控制是冷气候部署所必需的.
