In this study, a hydrophobic material, ethylcellulose, which was used as its aqueous suspension Surelease®, was combined with a swelling agent as the swelling layer to prepare delayed-release pellets for Danshensu, which is a hydrophilic drug with low MW. A rupturable, delayed-release pellet consist...
