The aim of this study is to determine the potency of drug available in our market in Bangladesh. 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. In vitro Dissolution study was performed to see that if potency is high but the drug is not bioavailable. Hardness is also checked to see that whether it interfere with the dissolution which ultimately effect the bioavailability. In this present study a simple, cost effective and spectrophotometric method for the potency determination of marketed Diclofenac Sodium tablets is used. Four samples were randomly collected from the market and coded as D01, D02, D03 and D04 and the potency determined are 99.30%, 103.38%, 98.22% and 102.16% respectively. Hardness and in vitro dissolution of the above four brands of Diclofenac Sodium tablets were also studied and reported in the paper. After 1 h Dissolution release of DO1, D02, D03 and D04 are 94.16%, 93.97%, 96.94% and 98.5% respectively. From all of the studies it seems that the samples were collected complies with the BP and USP requirements.
