The present study involves the ionic gelation of alginate molecules which offers a flexible and easily controllable process for the manipulating the characteristics of the beads which is important in controlling the release rate and consequently the absorption of Gliclazide from the GIT, variation in polymer, concentration, time of gelation in the external phase were examined systemically for their effects on rate release and entrapment efficiency by Plackett Burman’s factorial design. The swelling behavior strongly depends on the polymer concentration.
