Mechanism of action of Nabumetone

Nabumetone (nab ue' me tone) is a naphthyl alkanone and orally available antiinflammatory agent.  Like other NSAIDs, nabumetone is a potent cyclo-oxygenase (Cox-1 and -2) inhibitor, which blocks the formation of prostaglandins that are important mediators in pain and inflammatory pathways.  Nabumetone is a pro-drug and exerts anti-cyclo-oxygenase activity only after absorption and activation in the liver.  Like other NSAIDs, it has analgesic, antipyretic and antiinflammatory activities.
