Objective:
To assess the risk of perforation or hemorrhage of peptic ulcer on treatment with nonsteroidal antiinflammatory drugs (NSAIDs), both as a class and as individual agents.
Methods:
A case-control study of medication histories in 494 patients and 972 matched control subjects.
Results:
The increase in risk (odds ratio) with NSAID therapy was 5.1 times the risk in controls. The odds ratio for piroxicam was 6.3 (95% confidence interval [CI] 3.3-12.0), as compared with 2.9 for diclofenac, ketoprofen, and sulindac combined (95% CI 2.0-4.2). The effect of other risk factors was also considered, and the adjusted odds ratios were 4.1 for all NSAIDs, 6.4 (95% CI 2.8-15.0) for piroxicam, and 3.3 (95% CI 2.0-5.5) for diclofenac, ketoprofen, and sulindac combined.
Conclusion:
The estimate of overall risk of peptic ulcer complications with NSAIDs is similar to that found in other studies. There appear to be differences in risk between agents.
