Activity Description

Allopurinol, a xanthine oxidase inhibitor, is a urate-lowering medication that is FDA approved for managing gout, preventing tumor lysis syndrome, and preventing recurrent calcium nephrolithiasis in patients with hyperuricosuria. Other non-FDA-approved indications include Lesch-Nyhan syndrome-associated hyperuricemia and the prevention of recurrent uric acid nephrolithiasis. It is important to note that asymptomatic hyperuricemia is not an indication of allopurinol or any urate-lowering therapy. This activity outlines the indications, mechanism, pharmacology, contraindications, and adverse events associated with allopurinol drug therapy.
