Currently, the main treatments for hyperuricemia in clinical practice include the following types. One category is drugs that inhibit uric acid synthesis, primarily allopurinol and febuxostat. Allopurinol is a xanthine oxidase inhibitor, which mainly works by preventing the conversion of hypoxanthine and xanthine into uric acid through the inhibition of xanthine oxidase. Febuxostat, on the other hand, is a newer xanthine oxidase inhibitor and may be more effective than allopurinol in lowering blood uric acid levels. Another category includes drugs that promote the excretion of uric acid, suitable for patients with normal renal function and hyperuricemia. These mainly include probenecid, benzbromarone, and some use of thiazide diuretics, though their effectiveness for hyperuricemia is somewhat controversial. (Specific medications should be taken under the guidance of a physician.)
