A new sustained release microencapsulated drug delivery system employing bhara gum derived from Terminalia bellerica (roxb) has been proposed in this present study. The microcapsules were formulated by ionic gelation technique using famotidine as the model drug and were evaluated for particle size, sphericity measurement, yield percentage, drug entrapment efficiency, wall thickness, swelling property, in vitro drug release profile and drug release kinetic study. The effect of different drug: bhara gum ratio on in vitro drug release profile was examined and compared with guar gum remaining all the parameters constant. The gum microcapsules with good structure and satisfactory yield were produced. Microcapsules employing bhara gum exhibited slow release of famotidine over 10 hr. Fickian release was observed from most of the formulation with bhara gum. It was concluded that the gum possess substantial release controlling properties that could be used for sustained drug delivery.
