  2. Aim of workThe objective of this study was formulation of controlled drug release beads by loading the antiinflammatoryketorolactromethamine (KT)to gelritenatural polymer as a drug carrier. Eight formulations were prepared adopting 23 factorialdesign .

  3. Conclusion the formula of choice was that prepared with 2% gelrite , air dried and subjected to wax treatment (FIII) , FIII showed a lower ulcer index when compared to KT powder and the commercial formula(FB) , due to microencapsulation process and the protective effect of the natural polymer used on GIT. The prepared beads showed very good correlation between the in-vitro release studies and their anti-inflammatory effect.
