Our study aims to design a controlled drug delivery system for Levocetirizine dihydrochloride by using chitosan beads. The beads were prepared by ionotropic gelation process, with Sodium tri poly phosphate (TPP) as an ionic agent. The formed beads were then further crosslinked using glutaraldehyde and the excess glutaraldehyde were then washed. The physical properties of the prepared beads such as beads sizes, shapes, encapsulation efficiencies, invitro release and degree of swelling weredoi:10.7324/japs.2012.2839 fatcat:6li6j5f5nve3dljbliklhw6n4u
