Rational approach to long-term use of H2-antagonists.

| Abstract |
Although the approved indications for long-term histamine (H2) receptor-antagonists are limited to the management of hypersecretory states and prophylaxis against recurrent duodenal ulcer, these agents are often prescribed indiscriminately. Definitive guidelines concerning proper patient selection for prophylaxis against duodenal ulcer recurrence are lacking. Persons likely to benefit from maintenance therapy include those who smoke and those with a long duration of symptoms or prior history of an ulcer complication. Although not an approved indication, maintenance therapy to prevent recurrent gastric ulcer is appropriate for elderly persons receiving nonsteroidal anti-inflammatory drugs or in patients with poor cardiopulmonary status who may not tolerate surgery for an ulcer-related complication. The role of long-term H2-antagonist therapy in reflux esophagitis is not defined but may be appropriate in scleroderma and Barrett's esophagus. Finally, several miscellaneous conditions, including cystic fibrosis, Menetrier's disease, and pancreatic exocrine insufficiency, may benefit from long-term H2-antagonist therapy. Currently, clinical trials document the efficacy of maintenance therapy in duodenal ulcer for up to a three-year period; however, for gastric ulcer and chronic reflux esophagitis, the duration and benefit of long-term therapy is not established, and treatment regimens need to be individualized. Therapy may be required indefinitely in the miscellaneous states mentioned previously.
