Various exogenous and endogenous stimuli incite a complex reaction in vascularized connective tissue called inflammation. Non sterodial antiinflammatory drugs are used to reduce inflammation Preferential COX-2 inhibitors namely diclofenac and aceclofenac was taken for my present work and anti inflammatory effect was compared with control and with each other. Student-t-test-was done to compare result. It was found that inflammation varied significantly across the three groups (P=000) compared to control, in~lammation was less in both diclofenac and aceclofenac (P=00). Reduction of inflammation with diclofenac was less, in comparision to aceclofenac at end. Aceclofenac is more efficacious than diclofenac.
