Nonsteroidal anti-inflammatory drugs--the clinical dilemmas.
Physicians using nonsteroidal anti-inflammatory drugs (NSAIDs) are concerned that effective anti-inflammatory doses cause few gastrointestinal side effects. Among the causes of discontinuing therapy, upper gastrointestinal symptoms and the development of 'ulcer' complications are major concerns; endoscopic findings in asymptomatic users are not. Initial symptoms, poorly correlated with endoscopic findings, are relieved by anti-ulcer drugs and ameliorate with time of NSAID use in most patients. Symptoms accompanied by epigastric tenderness, or unrelieved by H2 antagonists, or resulting in cessation of NSAID therapy are more predictive of underlying ulcers. Complications probably arise in several ways, including as hemorrhages due to interference with platelet function, and as complications due to exacerbations of underlying ulcer disease or of ulcers caused by the NSAIDs. Pathogenesis and effective prophylaxis (yet to be established) may therefore vary in different patients, a clinical dilemma.
