The U.S. FDA approved AstraZeneca Pharmaceuticals’ Zurampic (lesinurad) to treat high levels of uric acid in the blood (hyperuricemia) associated with gout, when used in combination with a xanthine oxidase inhibitor (XOI), a type of drug approved to reduce the production of uric acid in the body.

Gout is a serious and debilitating form of inflammatory arthritis caused by hyperuricemia (elevated sUA). It affects millions of people around the globe, many of whom do not reach recommended sUA treatment goals on XOIs, which decrease production of uric acid. For those inadequately controlled patients, the addition of a urate-lowering therapy to increase excretion of uric acid may help them achieve treatment goals.  Zurampic  inhibits the urate transporter, URAT1, which is responsible for the majority of the renal reabsorption of uric acid. By inhibiting URAT1, Zurampic increases uric acid excretion and thereby lowers sUA.
