Reduction in urinary oxalate values by allopurinol.
A variety of substances have been used to prevent recurrence of stone disease. Recently there has been considerable interest in the ability of allopurinol to prevent stone recurrence. This article discusses the effect of allopurinol on the urinary oxalate in a group of stone formers. A significant reduction was obtained especially in subjects in whom the blood urate levels exceeded 300 mumol./L. Possible mechanisms explaining the mode of action of the drug are discussed.
