Can cyclooxygenase (COX)-2 inhibitors
be used to treat gout?

The COX-2 inhibitors reduce
inflammation while producing
less GI toxicity than traditional
NSAIDs. The efficacy
of COX-2 inhibitors has been
tested in patients with rheumatoid
arthritis (RA), osteoarthritis (OA),
dental pain, postoperative pain, and
dysmenorrhea—and is equivalent
to that of traditional NSAIDs. COX-2
inhibitors have not been formally
studied in acute gout; thus, there is
no evidence-based answer to your
question.
Nonetheless, one would intuitively
expect these agents to be as effective
as traditional NSAIDs for treatment
of the inflammation associated
with gout; there is anecdotal evidence
that they are. The main reasons for
prescribing a COX-2 inhibitor for a patient
with acute gout would be a history
of GI intolerance with traditional
NSAIDs or the presence of other risk
factors for peptic ulceration. The efficacy
of COX-2 inhibitors would probably
be no greater than that of traditional
NSAIDs at recommended
doses.
