As a first generation NSAID inhibitor, oxaprozin binds to and inactivates both isoforms of cyclooxygenase (COX-1 and-2), thereby blocking the conversion of arachidonic acid to pro-inflammatory prostaglandins.  When inhibiting COX-2, this agent may be effective in relieving pain and inflammation; when inhibiting COX-1, it may produce unacceptable gastrointestinal side effects. (NCI04)"}]
