Allopurinol is a xanthine oxidase inhibitor that prevents attacks of gout and renal stones in affected patients, and also treats some complications of cancer chemotherapy. It works by reducing the amount of a chemical called uric acid, which in high doses is responsible for these conditions. Allopurinol is not used to treat gout or renal stones, rather to prevent further attacks in patients already affected by these conditions.
