In another example of a hybrid DDS, ranitidine hydrochloride, the H2 histamine receptor inhibitor, was intercalated in MMT and coated with the cationic polymer Eudragit ElOO using an oil-in-water solvent evaporation method. The material obtained had the form of microparticles. It vras found that in the presence of Eudragit ElOO, both the release rate and the amount of drug released noticeably increased, because of the effective exchange of the polycation with intercalated drug molecules. In a similar...
