Advance in studies on film-controlled synchronized release multi-component preparations of Chinese materia medica for oral / 中草药

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.
