GI toxicity of rofecoxib compared to naproxen
Arthritis Research & Therapy volume 3, Article number: 66873 (2001)
The hypothesis that selective inhibitors of cyclo-oxegenase (COX)-2 (coxibs) would have less serious upper gastrointestinal (GI) toxicity than traditional non-selective nonsteroidal anti-inflammatory drugs (NSAIDs) has recently been affirmed for celecoxib (see Additional information). This study tests the hypothesis for rofecoxib in rheumatoid arthritis (RA).
Confirmed GI events were less with rofecoxib than naproxen (2.1 versus 4.5 per 100 patient-years, relative risk 0.5), as were the rates of complicated events (0.6 versus 1.4 per 100 patient-years, relative risk 0.4). The incidence of myocardial infarction (MI) was higher with rofecoxib than naproxen (0.4% versus 0.1%, relative risk 0.2).
This study confirms the hypothesis that selective inhibition of COX-2 in the treatment of RA is associated with significantly less GI toxicity than NSAIDs. However, treatment with neither celecoxib (see Additional information) nor rofecoxib completely eliminates serious GI toxicity in RA or osteoarthritis patients. The increased incidence of MI in the rofecoxib-treated patients occurred primarily in patients for whom low-dose aspirin would have been appropriate, but not allowed by the trial.
