Pegloticase is a pegylated recombinant uricase. Main outcome measure: ‘Immunomodulation’ helps make pegloticase, a medication for chronic gout, much more effective Uric acid-lowering medications such as allopurinol and febuxostat are staples of gout treatment, but for some patients these medications don’t work well enough to reduce gout flares, or they’re not tolerated. Colchicine first doze is 1.2mg followed by 0.6 mg after 12 hours and then once daily at 0.6mg. The primary endpoint was the proportion of patients who achieved plasma uric acid less than 6 mg/dL for at least 80% of the time during month 3 and month 6.

To systematically review the evidence on the efficacy, safety, and cost-effectiveness of urate-lowering therapy for gout: xanthine oxidase inhibitors (allopurinol and febuxostat), uricosuric medications (benzbromarone, probenecid and sulfinpyrazone), and uricases (pegloticase and rasburicase). Among patients with chronic gout, elevated serum uric acid level, and allopurinol intolerance or refractoriness, the use of pegloticase 8 mg either every 2 weeks or every 4 weeks for 6 months resulted in lower uric acid levels compared with placebo. Pegloticase has been granted EU marketing authorisation in patients who continue to have severe gout attacks despite treatment with a xanthine oxidase inhibitor such as allopurinol. Objective. Urate-lowering therapies (aka xanthine oxidase inhibitors) like allopurinol (Zyloprim), febuxostat (Uloric), pegloticase (Krystexxa), and probenecid Uloric and Allopurinol Similarities Uloric and allopurinol both reduce gout flares by decreasing the amount of uric acid in your blood. In total, 338 patients received pegloticase, prescribed by approximately 150 unique clinicians.
