1 BACKGROUND & AIMS: Selective inhibitors of cyclooxygenase (COX)-2 are being developed as gastrointestinal-sparing anti-inflammatory drugs based on the premise that this isoform is solely responsible for prostaglandin synthesis at sites of inflammation, whereas COX-1 produces prostaglandins important for maintenance of mucosal integrity. Prostaglandins cytochrome c oxidase II, mitochondrial Rattus norvegicus
2 BACKGROUND & AIMS: Selective inhibitors of cyclooxygenase (COX)-2 are being developed as gastrointestinal-sparing anti-inflammatory drugs based on the premise that this isoform is solely responsible for prostaglandin synthesis at sites of inflammation, whereas COX-1 produces prostaglandins important for maintenance of mucosal integrity. Prostaglandins cytochrome c oxidase II, mitochondrial Rattus norvegicus
3 The degree of suppression of prostaglandin synthesis at the site of inflammation correlated significantly with inhibition of COX-1 but not COX-2. Prostaglandins cytochrome c oxidase II, mitochondrial Rattus norvegicus
4 To achieve desirable anti-inflammatory effects, COX-2 inhibitors needed to be given at doses in which selectivity was lost, leading to suppression of gastric prostaglandin synthesis and to mucosal injury. Prostaglandins cytochrome c oxidase II, mitochondrial Rattus norvegicus
