Prevention and treatment of ulcers induced by nonsteroidal anti-inflammatory drugs.

Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) can cause varying degrees of gastroduodenal mucosal damage. These agents are most frequently used for the treatment of rheumatic diseases because they are highly effective in reducing joint pain and swelling. Histamine H2-receptor antagonists, omeprazole, sucralfate, and misoprostol are drugs available for the treatment of gastric mucosal damage caused by NSAIDs. In controlled clinical studies, all these drugs effectively heal gastric and duodenal injury if NSAIDs are discontinued. However, current data suggest that if NSAIDs are continued while gastrointestinal damage is present, only misoprostol and omeprazole have demonstrated efficacy in healing gastric mucosal injury. Misoprostol also effectively heals NSAID-induced duodenal injury. At this time, no data exist on the efficacy of other antiulcer drugs in healing duodenal erosions or ulceration if NSAID administration is continued. Regarding prevention of NSAID-induced gastric ulcer, controlled clinical studies with H2 antagonists and sucralfate have failed to show any therapeutic benefit. Ranitidine, however, has shown efficacy in preventing NSAID-induced duodenal ulcers. The coadministration of misoprostol with NSAIDs to patients who have either osteoarthritis or rheumatoid arthritis prevents the development of gastric and duodenal ulcers. Based on current published information, this property distinguishes misoprostol from other antiulcer drugs.
