中药制剂生产工艺设计空间的建立

质量源于设计(quality by design,QbD)的理念正推动着药品生产模式的转变,即从传统的以检验为主的制药过程到以科学和风险为基础并经过详细研究和理解的生产过程.随着对工艺的认识和理解不断深入,“设计空间”将被确定,质量控制从质量标准转移到设计空间.因此,设计空间的建立是实施QbD的核心步骤,研究设计空间的构建方法具有重要的意义.该文提出在中药制剂生产工艺中建立设计空间的设想,系统介绍了设计空间的概念,分析了在中药制剂生产工艺中构建设计空间的可行性和意义,结合实例提出符合中药制剂特点的设计空间研究方法,以及未来的研究方向.

Establishment of design space for production process of traditional Chinese medicine preparation

The philosophy of quality by design (QbD) is now leading the changes in the drug manufacturing mode from the conventional test-based approach to the science and risk based approach focusing on the detailed research and understanding of the production process. Along with the constant deepening of the understanding of the manufacturing process, the design space will be determined, and the emphasis of quality control will be shifted from the quality standards to the design space. Therefore, the establishment of the design space is core step in the implementation of QbD, and it is of great importance to study the methods for building the design space. This essay proposes the concept of design space for the production process of traditional Chinese medicine (TCM) preparations, gives a systematic introduction of the concept of the design space, analyzes the feasibility and significance to build the design space in the production process of traditional Chinese medicine preparations, and proposes study approaches on the basis of examples that comply with the characteristics of traditional Chinese medicine preparations, as well as future study orientations.
