The spherical microspheres consisting of Furosemide loaded sodium alginate and along with HPMC E50 or sodium CMC as mucoadhesive polymers in different ratios were prepared using ionic gelation technique. Calcium chloride was used as crosslinking, to retard the drug release from the mucoadhesive microspheres. The prepared mucoadhesive microspheres were subjected for evaluation of various parameters like production yield, particle size, encapsulation efficiency, mucoadhesion test and in vitro dissolution profile studies. Formulations were subjected to DSC study and SEM analysis. The in vitro release data were well fit into Higuchi and Korsmeyer-Peppas model and followed non-Fickian diffusion mechanism.

Keywords: Furosemide, Ionic gelation, Mucoadhesive polymers, Sodium alginate.
