  • Forty nine patients (26 normal excretors and 23 under excretors) were given allopurinol 300 mg/day and 37 under excretors benzbromarone 100 mg/day. (bmj.com)
  • Benzbromarone was introduced in the 1970s and was viewed as having few associated serious adverse reactions. (wikipedia.org)
  • It truly is estimated that, in Europe, if all reported cases of hepatotoxicity have been attributed to benzbromarone, then the risk would be 1 in 17,000. (lckinhibitor.com)
  • This was confirmed when she was rechallenged with benzobramone two years later.33 Inside the late 1990s and early 2000s in Japan, a number of situations of fulminant liver failure top to death have been attributed to benzbromarone.346 Ultimately, the drug was withdrawn from the market place by Sanofi-Synth abo in 2003 just after reports of extreme hepatotoxicity. (lckinhibitor.com)
  • It's worth noting that only one particular case (the Dutch lady) showed clear causation between benzbromarone and hepatotoxicity. (lckinhibitor.com)
  • The first alternative drug of choice was the xanthine oxidase inhibitor allopurinol. (nih.gov)
  • Benzbromarone is highly effective and well tolerated, and clinical trials as early as 1981 and as recently as April 2008 have suggested it is superior to both allopurinol, a non-uricosuric xanthine oxidase inhibitor, and probenecid, another uricosuric drug. (wikipedia.org)
  • Many patients with gout do not achieve their serum urate (sUA)-lowering targets during treatment with a xanthine oxidase inhibitor (XOI), for example, allopurinol or febuxostat, alone. (bmj.com)
