延期药制备工艺的研究进展

该文主要阐述了国内外延期药制备过程中的原料纯度、原料粒度、混药造粒工艺的研究现状和发展。根据国外的先进经验,结合我国的实际情况,提出一些延期药制备技术的具体研究和发展思路,为今后研究延期药精度提供一定的参考作用。

Progress in preparation of delay compositions

The current and development about purity、particle size、mixing technology and granulator in process of preparating delay compositions both at home and aborad are reviewed. According to the foreign advenced experiments and uniting the actual status of our country,some ideas in the research and development of preparation process of delay compositions are suggested to provide reference for the further study of precision extension of delay compositions.
