中药膜控型缓释制剂具有较高的释放调节操作性, 不同的包衣材料、包衣厚度及膜控型缓释技术可以控制口服中药膜控缓释制剂的释药速率、释放时间或释放部位, 易于实现中药中各成分的同步释放, 已成为主要的研究方向。通过整理归纳近几年中药缓释制剂的相关文献, 对口服中药膜控型缓释制剂进行综述, 以期为口服中药膜控缓释制剂的研究与开发提供参考。

The progress in the researches on film-controlled sustained-release preparations of Chinese material medica (CMM) for oral was introduced to provide the reference for further investigation and development of film-controlled sustained-release preparations of CMM for oral. This paper searched relevant literatures with sustained-release preparations of CMM. Choice of different coating material, coating thickness and preparation method can control the drug release rate of film-controlled sustained-release preparations of CMM for oral. This is beneficial to increasing operational regulation, so as to realize synchronized release of multi-component in the CMM.
