• Description: Nimesulide is a relatively COX-2 selective, non-steroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic properties. It is indicated for the treatment of acute pain, symptomatic treatment of osteoarthritis and primary dysmenorrhoea in adolescents and adults. However, due to the risk of causing hepatotoxicity, it should not be taken long-term. It has also been withdrawn from the markets in many countries. It mechanism of action is through targeting on various key mediators in the inflammatory process such as COX-2 mediated prostaglandins, free radicals, proteolytic enzymes and histamine. Nimesulide is a non-steroidal anti-inflammatory drug (NSAID) and COX-2 inhibitor (IC50s = 1.27 and 0.03 μM for the human and ovine enzymes, respectively). It is selective for COX-2 over COX-1 (IC50s = 70 and 22 μM for the human and ovine enzymes, respectively). Nimesulide also inhibits sodium-dependent neutral amino acid transporter (B0AT1) with an IC50 value of 23 μM for the rat kidney transporter. It inhibits infection-induced increases in brain prostaglandin E2 (PGE2; ) levels, as well as reduces pyresis (ED50 = 0.3 mg/kg), in yeast-infected rats. Nimesulide (2.9 mg/kg) inhibits formalin-induced hindpaw thermal hyperalgesia in rats.

The IC50 values are 70 and 1.27 μM for human recombinant COX-1 and -2 (at 20 μM arachidonic acid), respectively, and 22 and 0.03 μM for ovine COX-1 and -2 (at 100 μM arachidonic acid), respectively.[Cayman Chemical]
• Clinical Use: Nimesulide is a nonsteroidal antiinflammatory/analgesic agent useful in the treatment of rheumatoid arthritis, as well as acute inflammation such as that induced by periodontal surgery or urinary tract infections.
