What is the recommended first-line treatment for chronic gout flares occurring two or more times per year?

• A. Xanthine oxidase inhibitors
• B. Colchicine
• C. Probenecid
• D. Pegloticase

Answer: (A)

When gout flares happen repeatedly, the goal is to prevent further attacks by lowering the level of uric acid in the blood. The best first-line approach is a xanthine oxidase inhibitor, such as allopurinol or febuxostat. These drugs reduce the production of uric acid in the liver, steadily lowering serum urate and decreasing crystal formation over time, which translates into fewer flares.

Starting urate-lowering therapy often needs a careful plan because lowering uric acid can transiently trigger more flares. To counter this, clinicians commonly give low-dose colchicine or a nonsteroidal anti-inflammatory drug for several months while the uric acid target is reached. The target is usually a serum urate below around 6 mg/dL (lower if tophi are present).

Colchicine is effective for treating acute flares and can be used to prevent initiation flares, but it isn’t used as the primary long-term strategy to prevent chronic gout by itself. Probenecid, a uricosuric agent, and pegloticase, used for refractory cases, are not considered first-line options.
