Title: Therapy for Acute Gout: Does Initial Use of Allopurinol Effect Duration and/or Recurrence Rate of Acute Attacks
Brief Summary: Medical teaching suggests allopurinol should not be initiated in the setting of an acute attack of gout, as rapid lowering of serum urate may exacerbate the attack. This study tests the hypothesis that there is no difference in patient reported daily pain or flair occurrences with early versus delayed institution of allopurinol during an acute gout attack.


Options:
A: Inclusion Criteria:

* First medical contact for acute attack of gout.
* ACR criteria for acute attack of gout
* Crystal proven by arthrocentesis on day of enrollment
* Primary gout

Exclusion Criteria:

* Secondary Gout
* Tophaceous Gout
* Prior steroid, colchicine, or uric acid lowering therapy in the past 6 months.
* Uncontrolled CHF
* Unstable angina
* Renal insufficiency (entry CREAT \> 1.3)
* Anticoagulant therapy
* Immunosuppressive therapy or chemotherapy in the past 6 months
* Pregnancy; OR
* Known allergy to NSAID, colchicine, or allopurinol
B: Inclusion Criteria:

* Hyperuricemia (serum urate ≥8.0 mg/dL and gout by American Rheumatism Association Criteria
* Renal function defined as a serum creatinine level of \< 2.0 mg/dL and creatinine clearance of \> 20 milliliters per minute (mL/min) by Cockroft and Gault formula.

Exclusion Criteria:

* History of xanthinuria
* Intolerance to allopurinol
* Presence of renal calculi,
* Alcohol intake of ≥ 14 drinks/week
* Clinically significant medical condition
C: Inclusion Criteria:

* Has one or more of the American Rheumatism Association criteria for the diagnosis of gout.
* Females of childbearing potential who are sexually active must agree to use adequate contraception, and can neither be pregnant nor lactating from Screening throughout the duration of the study.
* Must have a serum urate level greater than or equal to 8.0 milligram per deciliter (mg/dL).

Exclusion Criteria:

* Have a severe, unstable, or life threatening medical condition that would likely prevent them from completing this study.
* Has a known body reaction to febuxostat, allopurinol, naproxen, any other non-steroidal anti-inflammatory drug (NSAID), aspirin, lansoprazole, colchicine, or any components in their formulation.
* History of xanthinuria.
* Alcohol consumption greater than 14/week.
* History of significant concomitant illness.
* Active liver or peptic ulcer disease.
* Has rheumatoid arthritis requiring treatment.
* Has estimated creatinine clearance less than 30 milliliter per minute (mL/min) calculated using the Cockcroft-Gault formula corrected for ideal body weight.
* Requires therapy with any other urate-lowering drug other than the study drug; long-term use of NSAIDs and COX-2 inhibitors; salicylates; thiazide diuretics; losartan; azathioprine; mercaptopurine; theophylline; intravenous (IV) colchicine; cyclosporine; cyclophosphamide; pyrazinamide; sulfamethoxazole;trimethoprim.
D: Inclusion Criteria:

* Male or female greater than 18 years of age;
* Previously met the preliminary criteria of the American Rheumatism Association (ARA) for the classification of the acute arthritis of primary gout;
* At least 2 gout flares in the year prior to the screening visit.

Exclusion Criteria:

* Acute gout flare within 2 weeks of the screening visit and during screening;
* Persistent chronic or active infections;
* History of an allergic reaction to allopurinol;
* History or presence of cancer within 5 years of the screening visit.
