Valdecoxib selectively binds to and inhibits cyclooxygenase (COX)-2, thereby preventing the conversion of arachidonic acid into prostaglandins, which are involved in the regulation of pain, inflammation, and fever. This NSAID does not inhibit COX-1 at therapeutic concentrations and therefore does not interfere with blood coagulation."}]
