Gout is the most common type of arthritis in developed countries that is often inadequately managed. Evidence regarding role of hyperuricaemia in poor outcomes in gout patients (e.g., disability, recurrent hospital admissions) with/without other chronic cardiometabolic comorbidities prompts the search of newer and more effective drugs. Current management of gout is limited to NSAIDS and intra-articular corticosteroids in acute gout and Allopurinol or Febuxostat with or without probenecid in chronic gout. Other drugs used as add-on therapy in refractory cases of gout who fail on monotherapy include benzbromarone and pegloticase but with limited role. Though these drugs have been available for several years, significant proportion of compliant patients fail to achieve consistent control of uric acid levels resulting in acute gout flares. Recent advances in the role of urate transporters in proximal tubules of kidney have resulted in the development of new generation uricosuric drugs including lesinurad. It is recently approved by US Food and Drug Administration (US FDA) and European Medicines Agency (EMA) in patients with uncontrolled gout along with Allopurinol or Febuxostat. Hopefully, it will contribute to fulfill the unmet goals in management of gout.
This review aims at exploring the current therapeutic strategies for the management of chronic gout patients as well as their limitations and the role of Lesinurad in patients who have failed on monotherapy. The published studies and poster presentations were identified by conducting a literature search from electronic database from 1980 till January 2017, using various medical subject headings and terminologies. These studies were screened and publications considered relevant to the topic were included in the study.
