Preventie van NSAID-gastropathie: verschil tussen een coxib en toevoeging van een PPI.

Several strategies are available for the prevention of NSAID gastropathy: the addition of misoprostol or proton pump inhibitors (PPIs) to conventional NSAIDs, or selective use of cyclo-oxygenase 2 inhibitors, the 'coxibs'. The recently published CONDOR study was a randomized trial comparing celecoxib with omeprazole in patients at high risk for NSAID gastropathy. A statistically significant reduction in the primary endpoint was found: hazard ratio: 4.3 (95% CI: 2.6-6.7; p < 0.0001). However, the reduction was largely based on a higher incidence of anaemia in the diclofenac plus omeprazole group. The study has strengths and weaknesses. The most important conclusion is that the nature of the gastro-protective effects of celecoxib and diclofenac/misoprostol are different.
