ABSTRACT

Microballoons are considered as one of the most promising buoyant drug delivery systems as they possess the advantages of both multiple-unit systems and good floating properties. The purpose of the present investigation was to characterize and evaluate microballoons of Allopurinol and to increase its boioavailability by increasing the retention time of the drug in the gastrointestinal tract. Sustained release floating microballoons containing allopurinol was formulated by solvent evaporation method using different polymer, DCM and ethanol as organic solvents and tween 80 as a processing medium. The prepared batches were evaluated for particle size, % entrapment efficiency, drug loading, floating time, total floating time and in-vitro drug release. The % entrapement efficiency was found to be 63.6 % to 84.83 %. Drug loading was found the range of 55.81 to 88.56 %. All the prepared microballoons remain on float condition over a period of 12 hrs. Formulation F1 showed the highest drug release of 83.93 % in 12 hrs. All other physical parameters were found satisfactorily. The results showed that the prepared floating microballoons of Allopurinol prove to be potential multiple-unit delivery devices for safe and effective sustained drug delivery.
