Role of COX-2 in nonsteroidal anti-inflammatory drug enteropathy in rodents

Abstract

The combination of COX-2 absence (or inhibition) and the topical effect of NSAIDs lead to changes characteristic of NSAID enteropathy without concomitant COX-1 inhibition and/or associated decreases in mucosal prostaglandins. COX-2 appears to be more important for maintaining small bowel integrity than COX-1.
