About

The aim of this study is to evaluate the efficacy and safety of simiaowan in prevention of acute flares in chronic gout patients initiating febuxostat therapy.

Full description

The study is a multicenter, randomized, double-blind, placebo-controlled, 12-week trial. To determine whether oral simiaowan at standard clinical doses (6g twice daily), compared to placebo, can reduce the incidence of acute gout flares and decrease the serum uric acid level.
