Mechanism of Action
Aceclofenac is a NSAID that inhibits both isoforms of Cyclooxygenase enzyme, a key enzyme involved in the inflammatory cascade. COX-1 enzyme is a constitutive enzyme involved in prostacyclin production and protective functions of gastric mucosa whereas COX-2 is an inducible enzyme involved in the production of inflammatory mediators in response to inflammatory stimuli. Aceclofenac displays more selectivity towards COX-2 than COX-1, which promotes its gastric tolerance compared to other NSAIDs. Although the mode of action of aceclofenac is thought to mainly arise from the inhibition of synthesis of prostaglandins (PGE2), aceclofenac also inhibits the production of inflammatory cytokines, interleukins (IL-1β, IL-6), and tumor necrosis factors (TNF). It is also reported that aceclofenac also affects the cell adhesion molecules from neutrophils.
