Development and Characterization of Mucoadhesive Microspheres Containing a Model Antidiabetic Drug

Abstract

The present work was envisaged to reduce the dosing frequency and improve patient compliance by designing and evaluating sustained release mucoadhesive (SRM) microspheres of metformin hydrochloride (MH) for an effective control of diabetes type-2. Microspheres were prepared by emulsification solvent evaporation method using sodium alginate, carbopol 934P (CP), and sodium carboxy methyl cellulose (SCMC) as a mucoadhesive polymers. The microspheres exhibits good mucoadhesive properties and showed high drug entrapment efficiency. MH release from these microspheres was slow and extended and dependent on the type of polymer used. The data obtained thus suggest that mucoadhesive microspheres can be successfully designed for sustained delivery of metformin hydrochloride and to improve patient compliance.
