Bazedoxifene was Effective in preventing glucocorticoid-indu
A Study was conducted to evaluate the effectiveness of bazedoxifene in preventing bone loss in patients with rheumatoid arthritis (RA) receiving low-dose glucocorticoids (GCs).

In this randomized, controlled, open-label study, researchers assigned postmenopausal women with osteopenia who had been receiving low-dose GCs for RA to two groups: a group receiving bazedoxifene (20 mg/day) with elemental calcium 1200 mg and vitamin D 800 IU daily (bazedoxifene group) and a group receiving the same doses of calcium and vitamin D only (control group).

As primary outcome, bone mineral density (BMD) change in the lumbar spine (L-spine) from baseline to 48 weeks was assessed. Changes in BMD in the femur, trabecular bone score, bone turnover markers, and development of fracture were assessed as secondary outcomes. For intention-to-treat analysis, 20 completed data sets were created by applying multiple imputations by chained equations.

Results:
--A total of 114 patients (57 patients in each group) were recruited. A significant increase in L-spine BMD (0.015 g/cm2) was observed in the bazedoxifene group, and the increase was significantly higher than in the control group.

--Reductions in bone turnover markers in the bazedoxifene group were significantly greater than in the control group.

--Only one fracture was observed in the bazedoxifene group, while four fractures developed in the control group.

Conclusively, in postmenopausal patients with RA receiving low-dose GCs, bazedoxifene improved BMD and reduced bone turnover markers. However, the change in BMD did not exceed the least significant change.
