NCIt definition : A sulfonamide derivative and non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory,
analgesic, and antipyretic activities. 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.;
Alternative definition : NCI-GLOSS: A substance that is being studied as a treatment for pain and other side
effects of cancer therapy. It belongs to the family of drugs called COX-2 inhibitors.;
