摘　　要：为成功设计蛋白及多肽类药物物理混合型干粉吸入剂提供理论和实践依据,本文综述和阐明了干粉吸入剂常用载体,药物微粉化制备技术,影响干粉吸入剂肺部沉积的处方工艺因素,包括载体性质、药物载体比例、混合顺序、混合方法和混合时间、药物载体相互作用,以及粉体学性质包括粒径大小和形态、密度、粉体流动性、带电性、分散性、吸湿性对肺部沉积率的影响。依据上述讨论和粉末分散的机制,提出了增加干粉吸入剂肺部沉积率的策略,包括加入载体细粉、加入黏附力控制物质和对药物微粉再加工等。因此,设计肺部沉积率高的蛋白及多肽药物的物理混合型干粉吸入剂需系统地研究药物与载体相互作用,阐明处方工艺及粉体学性质的影响。To provide theoretical and practical basis for the successful formulation design of physically-mixed inhalation dry powder of proteins and peptides, related references were collected, analyzed and summarized. In this review drug micronization technology and commonly used carriers for inhalation dry powder preparation were introduced. For proteins and peptides, supercritical fluid technology and spray-drying are more suitable because of their capabilities of keeping drug activity. Being approved by U. S. Food and Drug Administration, lactose has been extensively used as carriers in many inhalation products. Formulation and process factors influencing drug deposition in the lung, including carrier properties, drug-carrier ratio, blending order, mixing methods, mixing time and the interaction between drug and carrier, were elucidated. The size, shape and surface properties of carries all influence the interaction between drug and carrier. Besides, influence of micromeritic properties of the dry powder, such as particle size, shape, density, flowability, charge, dispersibility and hygroscopicity, on drug deposition in the lung was elaborated. Among these particle size plays the most crucial role in particle deposition in the lung. Moreover, based on the mechanisms of powder dispersity, some strategies to improve drug lung deposition were put forward, such as adding carrier fines, adding adhesive- controlling materials and reprocessing micronized drug. In order to design physically-mixed inhalation dry powder for proteins and peptides with high lung deposition, it is essential to study drug-carriers interactions systematically and illustrate the potential influence of formulation, process parameters and micromeritic properties of the powder.
