Description: White or almost white powder; Practically odourless. Very slightly soluble in water and in alcohol, insoluble in chloroform and in ether. It dissolves in dilute solutions of alkali hydroxides.
Usage: Allopurinol and its metabolic product are the only kind of drug which can inhibit the synthesis of cidum uricum. It has the ability to inhibit xanthine oxidase, which can prevent hypoxanthine or xanthine from transforming into acidum uricum. When the acidum uricum reduce, the concentration of acidum uricum in blood will lower, the deposition of urate on bone, joint and kidney will also reduce. Indication: Gout, gouty nephropathy, uric acid calculus.

Uses: The primary use of allopurinol is to treat hyperuricemia (excess uric acid in blood plasma) and its complications. Allopurinol does not alleviate acute attacks of gout, but is useful in chronic gout to prevent future attacks. Similarly, allopurinol commonly is used as prophylaxis with chemotherapeutic treatments, which can rapidly produce severe hyperuricemia. Other established indications for allopurinol therapy include ischaemic reperfusion injury, kidney stones with a uric acid component (uric acid nephrolithiasis) and protozoal infections (Leishmaniasis). Also used to prevent tumor lysis with certain types of cancer.
