中药缓控释制剂研究起步较晚，发展也较慢，处在初级阶段，但近年来，中药复方缓控释制剂的研究报道逐年增加，研究广度和深度显著加强，已成为当前中药制剂研究的前沿和热点。现就中药缓释制剂的研究进展情况、制剂的类型进行综述并提出研究思路，为中药缓控释制剂的研究和开发提供参考。

Research on sustained and controlled release preparation of traditional Chinese medicine is in primary stage now because of its start late and its development slow. But the amount of the reports increase year by year, the scope become more and more wide and the depth get more and more deep in recent years. In order to study and to exploitate them, we summarize research progress about drug study, dosage form and in vitro evaluation of sustained release preparation of CMM and research ideas of sustained release preparation of CMM in this text.
