Condition characterized by abnormally elevated levels of uric acid in the blood, recurring attacks of joint inflammation... Gout attacks (gouty arthritis) are caused by crystals of uric acid deposits. Patients with impaired liver function had no elevated risk for severe side effects. ursulagresser@email.de. Xanthine oxidase inhibitors are the drugs which are used to treat severe pain, tenderness and redness in the joints and abnormally high level of the uric acid in the blood.It blocks the activity of an enzyme (xanthine oxidase) which is responsible for the production of the uric acid. The most frequently reported side effects (without severe side effects) were headache, abdominal pain, and diarrhea, as well as a change in the frequency of micturition. Uloric (febuxostat) is a xanthine oxidase inhibitor used to treat gout caused by excessive levels of uric acid in the blood (hyperuricemia). * Of the patients who received The more common side effects include increased serum creatinine, headache, influenza, and gastroesophageal reflux disease.[Ref]. Although renal dysfunction may contribute to the rise in urate, the issue is much more complex because the same enzyme (xanthine oxidase [XO]) produces both urate and reactive oxygen species (ROS) like superoxide anions, and the improvement in vascular biology seen after XO inhibition could be due to a reduction in either urate or ROS. Herbs used for medicine have been studied and cultivated over thousands of years, which has resulted in detailed kno… Febuxostat is used for decreasing the symptoms of gouty arthritis. 13 In contrast, allopurinol, a purine analogue XO inhibitor, produces ROS when metabolized to oxypurinol. So, one way to prevent gout attacks is to inhibit, or limit, xanthine oxidase so that it cannot produce so much uric acid. Distribution.
