A sustained-release tablet formulation should ideally have a proper release profile insensitive to moderate changes in tablet hardness that is usually encountered in manufacturing. In this study, matrix aspirin (acetylsalicylic acid) tablets with ethylcellulose (EC), Eudragit RS100 (RS), and Eudragit S100 (S) were prepared by direct compression. The release behaviors were then studied in two co...

Many strategies have been developed to improve vaccine delivery in the past decade. The aim of the current study was to develop a nanoparticulate system based on ionic gelation between chitosan and tripolyphosphate in order to load Androctonus Crassicauda scorpion venom. The best formulation was selected according to the highest association efficiency, loading capacity, optimum particle size an...
