Microballoons is a novel technology of pharmaceutical field in the floating drug delivery for achieving gastric retention. Microballoons are gastro retentive drug delivery systems that are based on the non-effervescent approach. Generally microballoons are in spherical shape without a core. These microballoons are free flowing powder which consists of protein and synthetic polymers and the size ranges from 200 μm. These microballoons are low density systems which have sufficient buoyancy to float over the gastric fluid for prolonged period of time without any irritation to gastrointestinal tract. Microballoons are prepared by using different techniques such as simple solvent evaporation method, double emulsion method, phase separation coacervation method, polymerization method, spray drying method, spray congealing method and hot melt encapsulation method.
