Nonsteroidal anti-inflammatory drugs (NSAIDs) are probably the most common
cause of gastroduodenal injury in the United States today, Approximately ha
lf of patients who regularly take NSAIDs have gastric erosions, and 15%-30%
have ulcers when they are examined endoscopically. However, the incidence
of clinical gastrointestinal (GI) events caused by NSAIDs is much lower. Cl
inical upper GI events may occur in 3%-4.5% of patients taking NSAIDs, and
serious complicated events develop in approximately 1.5%. However, the risk
varies widely in relationship to clinical features such as history of ulce
rs or GI events, age, concomitant anticoagulant or steroid use, and NSAID d
ose. This review discusses the risks of clinical GI disease in NSAID users,
the predictors of increased risk, and strategies for prevention of NSAID-a
ssociated GI disease.
