Newer cyclo-oxygenase-2 selective inhibitors, other non-steroidal anti-inflammatory drugs and the risk of acute pancreatitis.Aliment Pharmacol Ther. 2006 Jul 01; 24(1):111-6.AP
Case reports have suggested that the use of newer cyclo-oxygenase-2 selective inhibitors may cause acute pancreatitis, but there has been no formal study of the association.
To assess the relationship between the use of cyclo-oxygenase-2 inhibitors and other non-steroidal anti-inflammatory drugs, and risk of acute pancreatitis.
A population-based case-control study was conducted using hospital discharge and prescription data from Denmark. Using conditional logistic regression with adjustment for multiple covariates, we estimated the relative risk of acute pancreatitis for use of the cyclo-oxygenase-2 inhibitors celecoxib and rofecoxib and for other non-steroidal anti-inflammatory drugs.
A total of 3083 cases of acute pancreatitis and 30 830 population controls were identified. For current use the relative risk estimate for celecoxib was 1.4 (95% CI: 0.8-2.3) and for rofecoxib was 1.3 (95% CI: 0.7-2.3). The overall relative risk for other non-steroidal anti-inflammatory drugs was 2.7 (95% CI: 2.4-3.0) with a substantial variation in risk between the individual drugs. The highest relative risk was for diclofenac (odds ratio 5.0, 95% CI: 4.2-5.9) and the lowest for naproxen (odds ratio 1.1, 95% CI: 0.7-1.7).
Cyclo-oxygenase-2 selective inhibitors are associated with a lower risk of acute pancreatitis than most other non-steroidal anti-inflammatory drugs.
