Description and Uses
Oxaprozin is a non-steroidal antiinflammatory agent indicated for use in various forms of rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis. A long T1/2 allows once/twice daily dosing. Structurally it is somewhat unique, being a 3- substituted, rather than a 2-substituted propionic acid.
