Inhibiteurus selectifs de la cyclo-oxygenase-2 et tube digestif

The use of non steroidal anti-inflammatory drugs [NSAIDS] is tempered by the development of side effects primarily in the gastro-intestinal tract. These effects result mainly from inhibition of the enzyme cyclo-oxygenase [COX]-1. Two NSAIDS [celecoxib and rofecoxib] COX-2 specific inhibitors had considerably lower ulcerogenic rates and lower serious gastro intestinal side effects when compared with other NSAIDs used in rhumatoid arthritis and osteoarthritis. However, the exact place of COX-2 specific inhibitors remain to be determined as compared with the association of other NSAIDs and proton pump inhibitors in the elderly. The efficacy of COX-2 specific inhibitors in digestive tumors is still unclear
