The objective of the present study was to develop controlled release matrix tablets of Aceclofenac by wet granulation method and solid dispersion technique using Eudragit RL100 as a rate controlled material. Drug-excipient computability studies were conducted by FT-IR and DSC, results showed no chemical interaction was observed between drug and excipient. The granules were evaluated found free flow properties. The tablets were subjected to thickness, hardness, friability weight variation and in-vitro drug release studies. Results of in vitro drug release studies revealed that drug release was controlled for 12hrs prepared by wet granulation method over the formulations by solid dispersion technique. The drug release pattern followed zero order kinetics and the mechanism of drug release was governed by peppas model. The ‘n’ values were found to be more than 1 (n>1) which indicated that the drug release was predominately controlled by super case II diffusion.
