Non-steroidal anti-inflammatory drug-induced gastroduodenal injury: therapeutic recommendations.

Non-steroidal anti-inflammatory drug (NSAID) use is associated with gastro-duodenal erosions and ulcers. Bleeding and perforation are reported complications in NSAID users. Therapeutic recommendations for NSAID-induced gastroduodenal injury are necessary because of our rapidly growing geriatric population, a steady increase in prescriptions for NSAIDs, and the widespread use of over-the-counter NSAIDs. Studies seem to indicate that there is no relationship between acute NSAID-induced mucosal injury and potential damage from chronic NSAID ingestion. Ranitidine (150 mg) b.d. effectively reduces the incidence of duodenal ulcer in NSAID users, but the same dose does not reduce the incidence of gastric ulcer. Misoprostol is effective in reducing the incidence of gastric ulcer in NSAID users, although confirmatory data on its effectiveness in preventing NSAID-induced duodenal ulcer are lacking. In addition to anti-ulcer therapy, treatment of NSAID-induced ulcers includes discontinuing the drug, reducing the dose, or switching to a less potent NSAID. Longer courses of anti-ulcer treatment may be required to achieve expected healing rates when NSAIDs are not discontinued. Results of treatment of NSAID-related ulcers with currently available anti-ulcer medications vary. Several studies have shown that 150 mg ranitidine b.d heals both gastric and duodenal NSAID-induced ulcers. Sucralfate has also been shown to heal NSAID-induced duodenal ulcers. Misoprostol treatment of NSAID-induced ulcers is not well documented, although there are placebo-controlled data that substantiate its benefit in gastric ulcer patients not taking NSAIDs.
