基于质量源于设计理念的中成药二次开发研究进展

质量源于设计(quality by design,QbD)理念是先进药品质控理念。将QbD理念应用于中药制药工艺研发时的主要步骤包括:确定关键工艺及其评价指标,辨识关键工艺参数和关键物料属性,建立关键工艺单元数学模型,构建设计空间,实施控制策略并不断改进。QbD理念还能指导建立中药及生产中间体的稳健分析方法。该文综述了在中成药二次开发中QbD方法的研究进展,并提出了今后的发展方向:QbD理念指导下研发中药新药和中药配方颗粒,过程模型化,发展基于工业大数据的控制策略,加强中药工艺放大规律研究,研制新型制药设备。

Research advances in secondary development of Chinese patent medicines based on quality by design concept

Quality by design (QbD) concept is an advanced pharmaceutical quality control concept. The application of QbD concept in the research and development of pharmaceutical processes of traditional Chinese medicines (TCM) mainly contains five parts, including the definition of critical processes and their evaluation criteria, the determination of critical process parameters and critical material attributes, the establishment of quantitative models, the development of design space, as well as the application and continuous improvement of control strategy. In this work, recent research advances in QbD concept implementation methods in the secondary development of Chinese patent medicines were reviewed, and five promising fields of the implementation of QbD concept were pointed out, including the research and development of TCM new drugs and Chinese medicine granules for formulation, modeling of pharmaceutical processes, development of control strategy based on industrial big data, strengthening the research of process amplification rules, and the development of new pharmaceutical equipment.
