SEM images reflect the surface properties prior and post drug diffusion studies, which indicates that release takes place predominantly by diffusion of TH through HCO matrix. DSC studies indicate no change in the respective spectra of initial and stability samples. FTIR studies indicate possibility of hydrogen bonding. Proton NMR data suggests characteristic peaks of TH being retained in the stability samples, indicating stable composition. Gamma radiation has led to significant reduction in viscosity of xanthan gum
