The frequency of gastrointestinal ulcers and ulcers complications induced by non steroidal anti inflammatory drugs (NSAID) increases continuously. This is a major health problem, since 1.5% of general population (mostly elderly people) take regularly NSAID'S. NSAID'S gastropathy is asymptomatic in nearly 50% of cases, even in case of big gastric ulcer. A severe hemorrhage or a gastric perforation can occurred in the absence of previous symptoms. When the patient had epigastric symptoms during a treatment with NSAID'S, upper GI endoscopy is normal in 50% of cases. NSAID'S are ulcerogenic by decreasing the capacity of the gastric mucosa to produce prostaglandin (PG) and by weakening gastric mucosal barrier. H2 blockers are not effective to prevent such lesions. Elderly women, are at high risk of gastric mucosal lesions and complications. In a prospective study, it was shown that misoprostol was effective to reduce the rate of NSAID'S induced gastric and duodenal ulcers. Up to date, epidemiologic studies don't show any population group at no risk of NSAID'S induced gastric lesions. The actual problem, now, is to determine which groups of patients are at high risk of complication in order to clarify the indications of preventive treatment. Today, in France, it's believed that old patients, with organic pathology (respiratory, cardiac, hepatic or urinary) and/or using two or more NSAID'S are at high risk.
