introduction
- a xanthine oxidase inhibitor introduced in 2015, as a new Rx to lower uric acid levels in patients with chronic tophaceous gout
- trials suggest it may be more effective than allopurinol but does risk cessation due to causing abnormal LFTs, and commencement needs to be covered with non-steroidal anti-inflammatory drugs (NSAIDs) or colchicine for 6 months as flare ups at commencement are more likely.
- other side effects appear to be similar to those of allopurinol
drug interactions
- xanthine oxidase inhibitors create serious interactions with azathioprine and mercaptopurine
dose
- for patients with tophi, start at 40mg/d, if urate levels > 0.36mM after 2-4wks Rx, then increase to 80mg/d
- trials have used doses up to 240mg/d but effectiveness was little better than 120mg/d and presumably had greater adverse effects
- no dose reduction is needed if creatinine clearance > 30 mL/min and liver function is not severely impaired
