基于QbD理念的中药新药成型工艺研发模式的探讨

中药制剂的生产大多采用比较传统的生产方式,产品的质量更多地依赖于终端控制。对其在生产过程中可能发生的问题不可预测,多数情况下仅依靠经验判断。由此,也很难找到影响生产工艺过程和产品质量的关键可控点。该文通过介绍中药新药成型工艺的最新研究成果,提出了基于QbD理念的中药新药成型工艺的研发模式,即借鉴粉体学和流体学的基本理论,表征中药制剂原料的物理属性,从加强制剂原料物理属性、制剂工艺、制剂产品质量之间相关性研究着手,更科学、合理地设计中药制剂成型工艺,并从中发现影响中药制剂质量的各种可能因素以及它们的影响程度,预测中试放大和生产过程中可能出现的问题,为中药制剂的研发与生产提供参考,也可为今后逐步实现中药制剂"过程控制"提供支撑。

Discussion on research and development of new traditional Chinese medicine preparation process based on idea of QbD

Traditional processes are mostly adopted in traditional Chinese medicine (TCM) preparation production and the quality of products is mostly controlled by terminal. Potential problems of the production in the process are unpredictable and is relied on experience in most cases. Therefore, it is hard to find the key points affecting the preparation process and quality control. A pattern of research and development of traditional Chinese medicine preparation process based on the idea of Quality by Design (QbD) was proposed after introducing the latest research achievement. Basic theories of micromeritics and rheology were used to characterize the physical property of TCM raw material. TCM preparation process was designed in a more scientific and rational way by studying the correlation among enhancing physical property of raw material, preparation process and product quality of preparation. So factors affecting the quality of TCM production would be found out and problems that might occur in the pilot process could be predicted. It would be a foundation for the R&D and production of TCM preparation as well as support for the "process control" of TCMIs gradually realized in the future.
