Abstract:- Chitosan-Gelatin/montmorillonite Cloisite 30 B (MMT) hybrid nanocomposites were prepared by blending chitosan-Gelatin with Cloisite 30B in aqueous solution. The nano composites were characterized by using FTIR, SEM and XRD analysis. From the FTIR spectra the various groups present in the chitosan-Gelatin blend were monitored. The homogeneity, morphology and crystallinity of the blends were ascertained from SEM and XRD data, respectively. The results indicated that an intercalated or partially exfoliated nanocomposite could be achieved, and the properties of the composite were significantly improved. The drug release kinetics was investigated using ketorolac as the drug. The kinetics of the drug delivery system has been systematically studied. Drug release kinetics was analyzed by plotting the cumulative release data vs. time by fitting to an exponential equation which indicated the non-Fickian type of kinetics. The drug release was investigated at different pH medium and it was found that the drug release depends upon the pH medium as well as the nature of matrix.
