Uloric Disease Interactions

No studies with febuxostat or lesinurad have been conducted in patients with secondary hyperuricemia (including organ transplant recipients). The use of these drugs is contraindicated in patients where the uric acid formation is greatly increased, such as patients with malignant disease, tumor lysis syndrome or Lesch-Nyhan syndrome.

Major adverse cardiovascular events (cardiovascular deaths, non- fatal myocardial infarctions and non- fatal strokes), were reported during clinical trials with some antihyperuricemic agents, such as febuxostat and lesinurad. Although a causal relationship has not been established, caution is advised when used in patients with cardiovascular disease. Monitoring for signs or symptoms of myocardial infarction or stroke is recommended.

There are insufficient data on the use of febuxostat in patients with severe renal impairment (ClCr less than 30 mL/min), therefore caution should be exercised on these patients. No dose adjustment is needed in patients with mild or moderate renal impairment.

No studies have been conducted in patients with severe hepatic impairment (Child-Pugh Class C), therefore caution should be exercised if using febuxostat or lesinurad on these patients. No dose adjustment is necessary in patients with mild or moderate hepatic impairment.
