xanthine oxidase inhibitors

Xanthine oxidase inhibitors are medications used to lower levels of uric acid in the body, which can help prevent gout attacks and certain types of kidney stones. They work by blocking the enzyme xanthine oxidase, which is responsible for producing uric acid during the breakdown of purines, substances found in many foods and drinks. By inhibiting this enzyme, these medications help reduce uric acid production, alleviating symptoms and preventing complications related to high uric acid levels. Common examples include allopurinol and febuxostat.
