Description
Curator's Comment: Description was created based on several sources, including https://www.drugs.com/uloric.html

Febuxostat (ULORIC) is a novel, xanthine oxidase/dehydrogenase (XO/XDH) inhibitor being developed by Teijin, TAP Pharmaceuticals, and Ipsen for the treatment of gout. The currently available XO inhibitor, allopurinol, has been associated with serious instances of severe hypersensitivity, in some cases leading to fatalities. There is some suggestion that febuxostat is less prone to excacerbate systemic inflammatory events in animal studies. Febuxostat, a xanthine oxidase inhibitor, achieves its therapeutic effect by decreasing serum uric acid. Febuxostat is not expected to inhibit other enzymes involved in purine and pyrimidine synthesis and metabolism at therapeutic concentrations. Febuxostat is used for the treatment of hyperuricemia in patients with gout.
