PRODUCT INTRODUCTION
Description
Allopurinol, a structural analog of hypoxanthine, is used primarily to treat hyperuricaemia and gout. Due to its inhibition of xanthine oxidase (E.C.1.2.3.2.), the enzyme that catalyzes the production of xanthine from hypoxanthine and uric acid from xanthine, both the plasma level of uric acid and its renal excretion is reduced. Allopurinol is a blocker and a substrate of xanthine oxidase; the oxidized metabolite, oxipurinol or alloxanthine, is also a potent inhibitor of xanthine oxidase. Recently, several new indications for allopurinol have emerged, for instance, prevention of tissue damage due to free radical formation, prevention of urinary stones, and treatment of protozoal diseases.
