Systemic biosynthesis of prostacyclin by cyclooxygenase (COX)-2: The human pharmacology of a selective inhibitor of COX-2

Prostacyclin Synthesis by COX-2 Endothelial Cells: Selective Up-Regulation of in Prostanoid Production by Human Roles of Cyclooxygenase (COX)-1 and COX-2

Growth stimulation of COX-2-negative pancreatic cancer by a selective COX-2 inhibitor.

Cyclooxygenase 2 (COX-2) inhibitors are promising antiangiogenic agents in several preclinical models. The aim of the present study was to evaluate the effect of selective COX-2 inhibitors on vascular endothelial growth factor (VEGF) production in vitro and angiogenesis and growth of pancreatic cancer in vivo, focusing on putative differences between COX-2-negative and COX-2-positive tumors. VE...

The pharmacology of selective inhibition of COX-2.

Selective inhibitors of cyclooxygenase (COX)-2 were developed to improve the safety of anti-inflammatory therapy in patients at elevated risk for gastrointestinal complications which are thought to be caused primarily by depression of COX-1 derived mucosal prostanoids. They were not expected to be more efficacious analgesics than compounds acting on both cyclooxygenases, the traditional (t) non...

Gastrointestinal tolerability of the selective cyclooxygenase-2 (COX-2) inhibitor rofecoxib compared with nonselective COX-1 and COX-2 inhibitors in osteoarthritis.

BACKGROUND Most nonsteroidal anti-inflammatory drugs (NSAIDs) are nonselective cyclooxygenase (COX-1 and COX-2) inhibitors and are associated with a variety of upper gastrointestinal (GI) tract symptoms. The roles of COX-1 and COX-2 in the pathogenesis of these symptoms are unclear. To test whether COX-2 inhibition with rofecoxib would have greater GI tolerability than nonselective COX-1 and CO...
