Interventions

For patients with serum uric acid levels&gt
6.0mg/dl,dotinurad 0.5mg/day will be added,or the dotinurad dosage will be adjusted so that serum uric acid levels are 2-6mg/dl and serum uric acid fluctuations are within 0.5mg/dl with follow-up ever
s wishes,personality,compliance,etc.For uric acid levels &lt
2.0mg/dl,dotinurad will be reduced or discontinued. (i)New dotinurad administration group:For patients with hyperuricemia (&gt
6.0mg/dl),dotinurad 0.5mg/day will be started after obtaining consent. Increase dotinurad to keep serum uric acid levels within 2-6mg at follow-up every 4(+/-2) weeks (ii) Dotinurad addition group t
Dotinurad 0.5mg 1mg Febuxostat 10mg 20mg 40mg
