摘要: 目的 分析吸入药物非临床评价的特点与要求,为吸入新药开发提供参考。方法 比较吸入途径给药与常规给药方式的特殊性,如吸入给药剂量计算、气溶胶发生、吸入给药系统可靠性、试验结果评价等,分析影响吸入药物非临床研究结果的因素,以进行合理设计、规范实施、科学分析非临床实验。结果 吸入药物的递送剂量由计算而得,但需要在此基础上估算沉积剂量;在吸入给药过程中需要对环境参数进行密切监测;吸入毒理实验的结果分析方面,啮齿类动物由于解剖及生理结构特点,上呼吸道易于产生炎症;对吸入给药在肺部引起的巨噬细胞聚集需要谨慎分析;吸入生物药在肺部的主要反应为炎症反应。结论 吸入药物存在药学特性及模型动物呼吸系统生理病理方面的特殊性,对非临床评价提出了特殊要求。

Abstract: Objective To analyze the features and requirements of non-clinical evaluation of inhalable drugs in order to provide reference for development of new inhalable drugs. Methods The characteristics of inhalable drugs were analyzed, such as generation of aerosols, dosimetry, reliability of the inhalation system, and interpretation of results. Factors that affected the non-clinical evaluation of inhalable drugs were identified so as to help design, conduct and analyze non-clinical experiments. Results The delivered dose of inhalable drugs was calculated, on the basis of which the deposited dose was estimated. During inhalation, the environmental parameters had to be monitored intensively. Inflammation in the upper airway was frequently noted due to the physiological and anatomical features of rodents. Aggregations of macrophages in the lung required cautious analysis. For inhalable biological drugs, the most common adverse reaction was inflammation. Conclusion The pharmaceutical properties of inhalable drugs place special demands on non-clinical evaluation.
