NCI Drug Dictionary

  

piroxicam 
A nonsteroidal oxicam derivative with anti-inflammatory, antipyretic and analgesic properties. As a non-selective, nonsteroidal anti-inflammatory drug (NSAID), piroxicam binds and chelates both isoforms of cyclooxygenases (COX1 and COX2), thereby stalling phospholipase A2 activity and conversion of arachidonic acid into prostaglandin precursors at the rate limiting cyclooxygenase enzyme step. This results in inhibition of prostaglandin biosynthesis. As a second, independent effect, piroxicam inhibits the activation of neutrophils thereby contributing to its overall anti-inflammatory effects. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
