Abstract Background: The aim of this work was to compare the dissolution behaviour of nine diclofenac sodium prolonged release tablets of different brands obtained from the Bangladesh market. The formulations contain the same amount of drug substance but different types and/or amount of excipients. Diclofenac Sodium is a potent Non-Steroidal Anti-Inflammatory Drug (NSAID) and that are widely used and it is an Over the Counter (OTC) drug in Bangladesh. Potency determination was performed to evaluate that the marketed sample comply with the declared specification or not. Study design: Total nine different brands (Diclofen, A-Fenac, Ultrafen, Mobifen, Genac, BtFenac, Clofenac, Diclofenac, Diclofenac-50) of diclofenac sodium tablets from different manufacturers were selected in the study. Place & duration of study: The cross sectional study was conducted in Southeast University Lab, Dhaka, Bangladesh from October 2018 to December 2018. Materials and Method: Diclofenac Sodium is a type of non-drug which is established to treat different symptoms by lessens the substances in the body that cause the pain and swelling to occur. Total ten different brands of Diclofenac tablets from different manufacturers were selected in the study. Dissolution testing was conducted according to USP from each brand for 25 minutes by using dissolution testing apparatus USP type-I (Basket). The tablets were subjected to various post-production tests such as hardness, physical parameters like weight variation, chemical parameters like assay, disintegration also considered for this study. Assay and Dissolution was checked by using a UV Spectrophotometer where Phosphate Buffer was used as dissolution medium. Result and Discussions: The disintegration, hardness and weight variation test of Tablets were performed as mentioned in BP or USP in world class equipment. All the results of these tests were matched USP standards. If the disintegration time, hardness, weight variation of Tablets varies a lot from the standard time, the tablets will not be able to show the desired therapeutic effect on time in the patients, which in result will increase the risk of patients. Conclusions: From the analysis of the results, this was observed that there was a considerable variation in the dissolution rates and also in the pattern of hardness, assay, friability, disintegration and weight of tablets.
