In this present study combination tablets containing diclofenac sodium, dried aluminium hydroxide gel and magnesium trisilicate were prepared using customized formula and common properties of tablets like hardness, thickness, diameter, weight and disintegration time along with the flow properties of granules were determined. Our results showed that most properties of the tablets complied with the official limit of acceptance. The pH, water absorption index, dissolution behavior and organoleptic property of tablets were also checked. Results showed that pH of combination tablets was 8.27 ± 0.04 when dissolved in purified water. Water absorption index varied from 0.1% to 0.2%. Tablets were undergone dissolution by 85% and 96% in 45 and 90 minutes respectively. In the study the organoleptic properties of the tablets remained the same over a period of 60 days.
