Xanthine-Oxidase Inhibitor

Xanthine-Oxidase Inhibitors (XOIs) are a class of drugs that work by inhibiting the enzyme xanthine oxidase, which is responsible for the breakdown of purine, a substance found in many foods. XOIs are used to treat gout and other conditions caused by excess uric acid in the body. They are also used to prevent kidney stones and to reduce symptoms of some cancers. XOIs work by blocking the action of xanthine oxidase, which prevents the breakdown of purine and thus reduces the amount of uric acid in the body. This helps to reduce pain and inflammation associated with gout and other conditions caused by excess uric acid. XOIs can also be used to reduce the risk of kidney stones and to reduce symptoms of some cancers.
