Extrusion-Spheronization VS Solution / Suspension Layering Technique

Purpose: The purpose of this study is to formulate itopride hydrochloride sustained release pellets by Extrusion¿Spheronization and Solution/ Suspension layering technique and to compare the pellet characteristics prepared from both the techniques. Methods: In the Extrusion-Spheronization technique, the drug pellets were prepared by mixing the drug with excipients along with a binder solution, the resultant mass was extruded through extruder followed by spheronizer. In Solution/suspension layering technology the pellets were prepared by coating the drug solution/suspension on the sugar spheres in a fluidized bed processor (FBP). The prepared drug pellets from both the techniques were seal coated with HPMC 5cps followed by sustained release coating of Ethyl cellulose 7cps in the FBP.
