Summary

药物干粉开发需要可靠的 体内 测试,通常使用小鼠模型。用于准确和可重复地将干粉气溶胶输送给小鼠的设备技术受到限制。本研究介绍了用于小鼠相关剂量的肺部药物递送的一次性给药器,有助于初步的概念验证研究。

Transcript

我们正在开发用于分枝杆菌疾病吸入治疗的新药和现有药物。我们的重点是治疗耐药微生物的新方法,确保使用干粉的安全性和有效性。干粉吸入器产品的初步临床前测试通常在小鼠模型中进行,然后再转移到更大的动物模型中。

这种方法的一个重大局限性是缺乏合适的设备技术,无法准确和可重复地将干粉输送给小动物。我们开发的一次性给药器易于制造,使其易于获得且具有成本效益,可用于小鼠的初步概念验证研究。一次性特性允许它们在动物手术室中使用,而无需担心清洁、重新填充和称量可重复使用设备的材料。

我们未来的工作将采用针对病原体的生物治疗部分,以避免对宿主产生任何影响。然后,这种方法可以针对患者进行定制,因为它具有病原体特异性。
