Allopurinol Sodium
Allopurinol Sodium is a xanthine oxidase inhibitor used to reduce uric acid production in the body. It is primarily prescribed for patients with gout, hyperuricemia, and certain cancer patients undergoing chemotherapy to prevent tumor lysis syndrome-related uric acid buildup. This medication requires consistent use and may initially trigger gout flares before providing symptom relief.
Allopurinol Sodium lowers uric acid levels to prevent gout attacks and related complications.

Chronic gout with recurrent attacks, tophi (uric acid deposits), gouty arthritis, hyperuricemia associated with chemotherapy (tumor lysis syndrome prevention), and recurrent calcium nephrolithiasis (kidney stones) associated with hyperuricemia.
Allopurinol inhibits xanthine oxidase, an enzyme responsible for converting hypoxanthine and xanthine to uric acid. By blocking this pathway, it reduces uric acid production and lowers serum and urinary uric acid levels.
May precipitate acute gout attacks during initial therapy; concurrent colchicine or NSAIDs are often prescribed. Requires adequate hydration to prevent kidney stone formation. Can cause serious skin reactions (Stevens-Johnson syndrome) and requires regular monitoring of liver function and blood counts. Should be taken with food to reduce GI upset.
