Febuxostat is a xanthine oxidase inhibitor used for treating gout caused by excessive levels of uric acid in the blood (hyperuricemia). cimmino@unige.it . The sensitivity analyses confirmed the disproportionality for these two ULTs. Similar to allopurinol, febuxostat blocks the metabolism of hypoxanthine and xanthine (oxypurines) to uric acid, thus reducing uric acid blood and urine concentrations. The mechanism of action is achieved through binding in a long, narrow channel leading to the molybdenum-pterin active site of XO, filling most of the channel and the immediate environment of the cofactor. M. Cutolo, M.A. ACR considers febuxostat as a first line ULD [110], whereas for EULAR, the drug is indicated in … Uric acid is the end product of purine metabolism in humans and is generated in the cascade of hypoxanthine → xanthine → uric acid. ... in patients with a history of heart disease and to ask for a postlicensing cardiovascular safety trial comparing febuxostat to allopurinol, the results of which are still pending [168].

A dose-related reduction in the risk of dementia in older adults was noted with higher allopurinol dose and with febuxostat 40 mg daily dose. Xanthine oxidase inhibitors reduce serum uric acid concentrations by blocking the transformation of hypoxanthine to xanthine and of xanthine to uric acid. Last Update. Results: Forty-nine and 51 patients took febuxostat and allopurinol, respectively. The infusion takes place over 30 minutes and the peak plasma concentration of allopurinol is reached in about 30 minutes.

There was no significant difference in the rate of achievement of the target serum UA level (<6.0 mg/dl) between the two groups at the start of this study (45.1 % in the febuxostat group vs 50 % in the allopurinol group, P = 0.70), but after 1-year of treatment, in this study, the achievement rate was significantly higher in the febuxostat group than in the allopurinol group (68.6 % vs 31.8 %, P < 0.01). Gastro-intestinal system • Greater proportion of Febuxostat-treated patients have decreased size and number of tophi. Compared with allopurinol use for 1 to 180 days, longer allopurinol or febuxostat use durations were not significantly associated with differences in HR of dementia (range of 0.76 to 1.14). Xanthine oxidase is responsible for the successive oxidation of hypoxanthine and xanthine, resulting in the production of uric acid, the product of human purine metabolism. We used 1:5 propensity-matched Cox regression analyses to compare the hazard ratio (HR) of incident dementia with allopurinol vs. febuxostat, assessing use, dose and duration. mechanism of action reduces inflammation; drugs nonsteroidal anti-inflammatory drugs (NSAIDs) glucocorticoids (oral, intra-articular, and parenteral) colchicine ; Drugs to avoid low-dose salicylates .
