Research progress and maturity assessment of continuous manufacturing of traditional Chinese medicine / 中国中药杂志

The pharmaceutical manufacturing model is gradually changing from intermittent manufacturing to continuous manufacturing and intelligent manufacturing. This paper briefly reviewed the supervision and research progress in continuous pharmaceutical manufacturing in China and abroad and described the definition and advantages of continuous pharmaceutical manufacturing. The continuous manufacturing of traditional Chinese medicine(TCM) at the current stage was summarized in the following three terms: the enhancement of the continuity of intermittent manufacturing operations, the integration of continuous equipment to improve physical continuity between units, and the application of advanced process control strategies to improve process continuity. To achieve continuous manufacturing of TCM, the corresponding key technologies, such as material property characterization, process modeling and simulation, process analysis technology, and system integration, were analyzed from the process and equipment, respectively. It was proposed that the continuous manufacturing equipment system should have the characteristics of high speed, high response, and high reliability, "three high(H~3)" for short. Considering the characteristics and current situation of TCM manufacturing, based on the two dimensions of product quality control and production efficiency, a maturity assessment model for continuous manufacturing of TCM, consisting of operation continuity, equipment continuity, process continuity, and quality control continuity, was proposed to provide references for the application of continuous manufacturing technology for TCM. The implementation of continuous manufacturing or the application of key continuous manufacturing technologies in TCM can help to systematically integrate advanced pharmaceutical technology elements and promote the uniformity of TCM quality and the improvement of production efficiency.

Formulation of technical guidelines in line with characteristics and principles of traditional Chinese medicine changes to improve quality of such preparations--interpretation of Technical guidelines for the study of pharmaceutical changes in traditional Chinese medicines / 中国中药杂志

In leading the high-quality development of Chinese medicine preparations, it is an important link to formulate the scientific, reasonable, and feasible guidelines for the change of Chinese medicines in accordance with the change characteristics and principles of the Chinese medicines is an important work to promote the Technical guidelines for the study of pharmaceutical changes in traditional Chinese medicines was formed by a broad consensus based on the characteristics and research results of the pharmaceutical changes in Traditional Chinese Medicines(TCM)with the principles of science and risk management. This guideline has clarified the basic principles and requirements for the evaluation of changes in TCM, specified the research and verification work of common change scenarios, defined the boundaries of changes in TCM, and proposed to encourage the use of new technologies, new methods, and new excipients that meet product characteristics. It will definitely promote the quality improvement and the secondary development of TCM. In this article, the revision background and main content of the guideline were introduced, and the main features of the Guideline were analyzed, in order to provide references for the industry.
