MedKoo CAT#: 510301

CAS#: 1151516-14-1 (sodium)

Description: Lesinurad, also known as RDEA594, is a selective uric acid re-absorption inhibitor (SURI) and is also a selective inhibitor of URAT1, a transporter in the kidney that regulates uric acid excretion from the body. RDEA594 has been shown to normalize the amount of uric acid excreted by gout patients previously classified as under-excretors. Lesinurad received FDA approval on December 22, 2015.
