The aim of this study was to formulate and evaluate polymeric tablets of Ketoprofen for the release rate, and mechanism. Formulations with different types and grades of Ethyl Cellulose Ether derivatives were prepared in several drug-to-polymer ratios (D:P ratio 10:1, 10:2 and 10:3). These formulations were compressed into tablets using the direct compression method. They were examined for the physical properties and appearance. Tablet dimensional tests i.e., (thickness, diameter) and QC tests (hardness, friability, and disintegration) were performed according to the USP methods. Invitro dissolution was performed. In order to analyze the drug release kinetics from each of the prepared matrices, five standard mathematical models were applied to the release data. The study showed that in case of tablets containing Ethocel premium polymers of 7, 10, and 100 grades show approximately 90-98% release of the drug from tablet in 24 hours compared to the Ethocel FP premium of 7, 10, and 100 which showed less release in 24 hours following nearly zero order kinetics.
