摘要

The aim of this work was to study the possibility to obtain an oral extended-release dosage forms with zero order kinetic release by coating minitablets (containing metoprolol tartrate) with insoluble methacrylate film coating (Eudragit NE 40D) in a fluidized bed system. To achieve this aim a full factorial experimental design with two factors and three levels was used in order to study de influence of the amount of polymer film formatting (Eudragit NE 40D) and the amount of pore generating excipient in polymeric insoluble film (low viscosity hydroxypropyl methylcellulose-Methocel E 15LV) on the in vitro drug release profile.
