A multiple unit oral floating drug delivery system of famotidine was developed to prolong gastric residence time, target stomach mucosa and increase drug bioavailability. Drug and polymer compatibility was studied by subjecting physical mixtures of drug and polymers to differential scanning calorimetry. DSC study decreases in sharpness and enthalpy of drug characteristic peak indicate the drug goes in to microspheres and reduces its crystalline as well as formulations goes in to amorphous state which indicates glass transition temperature.
XRD graph of pure 5-Fluorouracil drug. It is concluded that drug was crystalline in nature due to the sharpness in peak height. Sharpness in peaks was decreased in microspheres that indicated drug in the both the formulation goes to the amorphous nature which can enhance bioavailability.SEM showed that microspheres of drug with ethyl cellulose and eudragit RS 100 were smooth and porous almost spherical microspheres. The rough surface which may be due to presence of drug crystals on the surface of microspheres.
