The sustained release fatty matrix tablet of Diclofenac sodium and Theophyllinee were prepared using melt granulation technique. The tablets were prepared using carnauba wax (CW) and stearic acid (SA) / emulsifying wax (EW) in the varying ratios. The evaluation of granules was done for angle of repose, Hausner`s ratio, Carr`s compressibility index, and sieve analysis. Tablets were evaluated for hardness, friability, content uniformity, weight variation and dissolution test. The dissolution study show the controlled release of the drug from tablets depending on concentration of wax. The invitro dissolution study show that for the formulation of Diclofenac prepared by using highest concentration of carnauba wax show maximum sustained activity whereas for tablets of Theophylline, the formulation containing highest concentration of stearic acid show maximum sustained release activity.
