Which drug also targets xanthine oxidase in its mechanism of action?

• A. Probenecid
• B. Febuxostat
• C. Allopurinol
• D. Corticosteroids

Answer: (B)

Febuxostat is a medication specifically designed to inhibit xanthine oxidase, an enzyme that plays a crucial role in the production of uric acid from purines. By inhibiting this enzyme, febuxostat effectively reduces uric acid levels in the blood, making it useful in the management of gout and other conditions associated with hyperuricemia. In comparison, allopurinol, while it also targets xanthine oxidase, is an older drug in this category. It functions similarly to febuxostat by decreasing uric acid production but has a different chemical structure and pharmacological properties. Probenecid works by a different mechanism, primarily promoting the excretion of uric acid in the urine, rather than inhibiting its production. Corticosteroids, on the other hand, are anti-inflammatory agents used to treat symptoms associated with gout flares but do not directly affect xanthine oxidase or uric acid levels. Thus, febuxostat is the correct choice as it specifically targets xanthine oxidase in the same way that allopurinol does, but it represents a more modern option with distinct pharmacological attributes.
