Abstract: Objective To systematically investigate the factors of preparation of ethyl cellulose ethoce matrix sustained-release tablets for water-soluble drug. Methods Cordilox was taken as a water-soluble model drug, accumulative release rate was taken as index testing by ultraviolet spectrophotometry,to study the influencing factors through single-factor test, to determine the release degree of ethyl cellulose ethoce matrix sustained-release tablets. Results These preparation parameters such as preparation method, amount, viscosity and grain size and manufacturer of ethyl cellulose ethoce, tablet hardness and specific surface area that were proved to had significantly influence on the accumulative release rate. Conclusion After a series of comprehensive researches, some references could be provided for further study on in vitro release of water-soluble drug from ethyl cellulose ethoce matrix sustained-release tablets.
