Brief Summary

The purpose of this clinical trial is to determine whether dipyridamole can treat restless legs syndrome in patients with uremia. In addition, the safety of dipyridamole will also be evaluated. The main questions this study aims to answer include: Can dipyridamole improve the symptoms of restless legs syndrome in participants? Can dipyridamole improve participants' anxiety, depression, sleep quality, and quality of life? What adverse reactions might participants experience while taking dipyridamole? This study is a self-controlled trial in which all participants receive active drug treatment. Participants will take dipyridamole daily (50 mg per dose, three times a day) for 12 weeks. The efficacy of dipyridamole will be evaluated by comparing relevant scale scores and laboratory indicators before and after treatment. In addition, adverse reactions during the treatment follow-up will be monitored to assess the safety of dipyridamole in this patient population.
