[Aggressiveness of NSAIDs versus digestive system mucosa]

NSAID induced gastropathy is linked to the inhibition of endogenous synthesis of prostaglandins. Gastropathies are made of erythematous, erosive or ulcerative lesions. Their localization is mainly antral or prepyloric. Their incidence is quite large and very severe in the elderly patient treated for long time with NSAID. The author presents several strategies either to prevent (with administration of misoprostol) or to treat (with prescription of omeprazole) this iatrogenic gastropathy.
