Which of the following drugs is contraindicated for acute gout treatment?

Allopurinol is contraindicated for the treatment of acute gout because it is a xanthine oxidase inhibitor that lowers uric acid levels, and it is primarily used for long-term management of chronic gout rather than for treating acute attacks. Initiating allopurinol during an acute gout flare can potentially exacerbate the condition and increase pain, as it may result in a mobilization of uric acid from tissues into the bloodstream, leading to higher uric acid levels and additional inflammation.

In contrast, drugs like indomethacin, colchicine, and naproxen sodium are anti-inflammatory agents that are effective in managing acute gout attacks by reducing pain and inflammation. Indomethacin and naproxen sodium are nonsteroidal anti-inflammatory drugs (NSAIDs) that alleviate symptoms effectively during a flare, while colchicine specifically targets the inflammatory process associated with gout. Thus, allopurinol should not be used until the acute episode has resolved and it is appropriate for long-term uric acid management.
