Abstract

This paper surveys the release drug systems and preparation technologies of sustained and controlled release preparations,and analyzes the problems and prospect during the study of sustained and controlled release preparations. There are three types of release drug systems in sustained and controlled release preparations, including time-controlled,site-controlled and speed-controlled. The preparation technologies mainly include film coating,combined matrix,osmotic pump,ect.
