IntroductionGout is a common form of inflammatory arthritis caused by deposition of monosodium urate crystals. The central strategy for effective long-term management of gout is serum urate lowering. Current urate-lowering drugs include both xanthine oxidase inhibitors and uricosuric agents. Lesinurad is a URAT1 inhibitor that selectively inhibits urate rebsorption at the proximal renal tubule. Lesinurad 200mg daily in combination with a xanthine oxidase is approved for urate-lowering therapy in patients with gout. Areas covered: The published literature was searched using Pubmed and additional information was obtained from publically available regulatory documents. Pre-clinical data and clinical trials of lesinurad are described. Serum urate-lowering efficacy and effects on other clinical endpoints are discussed. Adverse event data, focusing on renal safety are also presented. Expert opinion: Lesinurad is an effective urate-lowering drug that has a generally acceptable safety profile when used at 200mg daily dosing in combination with a xanthine oxidase inhibitor. The recent approval of fixed dose combination pills of lesinurad with allopurinol is an important step in improving adherence and reducing risk of renal adverse events. It remains to be seen if this therapy will provide additional benefit for gout management above improved use of widely available generic therapies.
