Does Allopurinol Prolong a Treated, Acute Gout Flare?
Traditional teaching holds that starting allopurinol during an acute gout attack will prolong the attack. Recent expert opinion from the American College of Rheumatology Guidelines is that allopurinol may be started during an acute, treated gout attack. This study is designed to test the hypothesis that allopurinol does not prolong an acute, treated gout attack. Patients will either take allopurinol capsules or and identical capsule containing no allopurinol (placebo) over 28 days, starting within 72 hours of a gout attack that is being treated with other standard measures. During the study, neither the patient nor the examiner will know what pills are being taken. The time to resolution of the attack is the primary outcome measure. Pain level, serum uric acid level, and complications of therapy will also be monitored. A minimum of 32 patients completing the study are needed for a meaningful conclusion.

- The primary outcome unit of measurement is time (in days) to resolution of the acute gout attack [ Time Frame: 1-28 Days ] [ Designated as safety issue: Yes ]
- Change in patient rated pain over time [ Time Frame: Pateints are assessed at five time intervals over 28 days: days 1, 3-4, 10-15, 20-25, and 28 ] [ Designated as safety issue: Yes ]Patient rated pain on a Likert pain score of 1-10
- Change in physician global assessment of gout activity [ Time Frame: Pateints are assessed at five time intervals over 28 days: days 1, 3-4, 10-15, 20-25, and 28 ] [ Designated as safety issue: Yes ]Physician rated gout activity on a Likert scale 1-10.
- Change in serum uric acid level [ Time Frame: Pre-study and at day 28 ] [ Designated as safety issue: No ]Blood test (serum) for uric acid level
