Risk of upper gastrointestinal events with the use of various NSAIDs: A case-control study in a general population

Objective. The gastrointestinal (GI) safety of different non-steroidal anti-inflammatory drugs (NSAIDs) in a real-life setting remains ill defined. The aim of this study was to examine the risk of upper GI events associated with various NSAIDs in a general population. Material and methods. A nationwide, register-based, matched case-control study was carried out in outpatient residents of Finland in 2000–04. Cases with upper GI events (n=9191) were drawn from the Hospital Discharge Register and individually matched to controls (n=41,780) from the Population Register. Results. The semi-selective NSAIDs (nimesulide, nabumetone, meloxicam, etodolac) had the highest odds ratio for upper GI events even after adjusting for various potential confounders (adjusted odds ratio (AOR) 3.63; 95% CI 3.08–4.28), followed by non-selective (2.98; 2.70–3.29) and COX-2 selective NSAIDs (2.53; 2.09–3.07). When the current use of semi-selective NSAIDs was compared with that of non-selective and COX-2 selective NSAIDs, the AORs...
