Lesinurad (Zurampic) is used to treat patients with gout. In gout, high levels of uric acid cause excess urate crystals to deposit in the joint, creating a hot, swollen, painful joint; the primary manifestation of gout. Lesinurad decreases uric acid by increasing the amount excreted in the urine.
Lesinurad is taken once daily as a tablet by mouth in combination with a xanthine oxidase inhibitor, such as allopurinol or febuxostat. It is not recommended to take lesinurad without a xanthine oxidase inhibitor. If taken alone, it has a high chance of causing kidney failure. Trying to adhere to a gout-specific diet can also help to improve uric acid levels.
The most concerning side effect of lesinurad is that it can cause kidney damage and kidney failure. You should not use lesinurad if you are allergic to it, have kidney or liver failure, are a dialysis patient, have a renal transplant, or have Lesch-Nyhan syndrome.
It should also be avoided if you have tumor lysis syndrome. Minor side effects include headache, flu-like symptoms, and heartburn. Effects of lesinurad on an unborn baby are unknown. It is also unknown if it passes into breast milk.
