CAS#: unknown

Description: Oxaprozin-d5 is intended for use as an internal standard for the quantification of oxaprozin by GC- or LC-MS. Oxaprozin is a non-steroidal anti-inflammatory drug (NSAID) and COX inhibitor (IC50s = 2.2 and 36 μM for human COX-1 and COX-2, respectively). It decreases acetic acid-induced writhing times and carrageenan-induced paw edema in mice when administered at doses of 100 and 70 mg/kg, respectively. Formulations containing oxaprozin have been used in the treatment of pain associated with osteoarthritis and rheumatoid arthritis.
