Eudragit NE30D based metformin/gliclazide extended release tablets: formulation, characterisation and in vitro release studies.

Metformin/Gliclazide extended release tablets were formulated with Eudragit NE30D by wet granulation technique. Two batches were prepared in order to study influence of drug polymer ratio on the tablet formation and in vitro drug release. The formulated tablets were characterized by disintegration time, hardness, friability, thickness, weight variation, and in vitro drug release.
