Effects of Cycle Therapy vs Sequential Therapy With Romosozumab and Denosumab in Postmenopausal Osteoporosis Patients

Summary

This study is a prospective, randomized, controlled clinical trial comparing the efficacy of a 24-month cyclic therapy regimen (6 months of Romosozumab followed by 6 months of Denosumab, repeated for two years) versus a traditional sequential treatment regimen (12 months of Romosozumab followed by 12 months of Denosumab). The goal is to determine which approach yields better therapeutic outcomes and to optimize drug strategies for osteoporosis patients.
