Carbohydrate polymeric blend microspheres of sodium alginate and methylcellulose were prepared and characterized by differential scanning calorimetry, scanning electron microscopy, and particle size distribution. DSC thermograms have confirmed the uniform molecular distribution of the drug molecules in the microspheres. SEM micrographs exhibited a spherical morphology of the prepared microspheres. The drug was released in a controlled manner. The swelling studies of microspheres have shown that with an increasing amount of MC in the microspheres, water uptake has decreased. This effect is correlated with the release rates of the drug though the microspheres containing different amount of MC. The microspheres have shown lower densities and hence, these could be retained in the gastric environment for more than 12 h, which would help to improve the bioavailability of nifedipine.
