Evaluation of Treatment Success Rate Among Antihyperuricemic Using Real-World Data.

Abstract

In this study, treatment and the serum uric acid (UA) level were compared using medication history generated by prescription order records of antihyperuricemic to examine the treatment success rate. We examined the treatment success rate among these patients based on the serum UA level during 120-180 days after the initiation of treatment, which was set as the endpoint. The number of patients whose UA level before the start of treatment was > 8.0 mg/dL but decreased to < 6.0 mg/dL after the treatment, which is the target treatment success, was 92 (success rate of 14.2%), 50 (53.2%), 76 (41.5%), 35 (31.9%), and 45 (37.8%) in the allopurinol 100 mg/day (A1) and 200 mg/day (A2), febuxostat 10 mg/day (F1) and 20 mg/day (F2), and benzbromarone 50 mg/day (B), respectively. Compared with that of the other drugs, the treatment success rate was high with A2 and low with A1. From the generated medication history, the treatment success rate with antihyperuricemic can be extracted mechanically.
