Xanthine Oxidase Inhibitor

A potent medication used to reduce the production of uric acid in the body, primarily indicated for the chronic management of gout, the prevention of tumor lysis syndrome during chemotherapy, and the treatment of recurrent calcium oxalate or uric acid kidney stones

Pharmaceutical Active Ingredient

A purine analogue that undergoes hepatic metabolism to its active metabolite, oxypurinol, both of which competitively inhibit the enzyme xanthine oxidase to lower serum and urinary urate concentrations

Antigout Agent

A standard-of-care therapeutic utilized to prevent gouty arthritis and the formation of tophi by maintaining serum uric acid levels below saturation points

Research Tool

A biochemical reagent used in scientific studies to investigate purine catabolism, reactive oxygen species generation, and the role of adenosine signaling in nociceptive pathways.
