Comparison of several early drug interventions in postmenopausal women with osteopenia

Two hundreds postmenopausal women with osteopenia, aged 45-80, were randomly divided into 4 groups, and received different drug interventions. After treatment for 12 months, the lumbar spine bone mineral density(BMD)and total hip BMD in alendronate group increased significantly(3.5% and 2.6%, both P＜0.05), the lumbar spine BMD raised 2.0% in selective estrogen receptor regulator group(P＜0.05). Bone turnover indices improved in both groups(all P＜0.05). No change in BMD or bone turnover indices was found in patients treated with active vitamin D3and calcium.
