ABSTRACT

Objective To evaluate the clinical efficacy of domestic bisphosphonates (etidronate and alendronate) in the treatment of postmenopausal osteoporosis. Methods Eighty three patients with postmenopausal osteoporosis were divided randomly into three groups group Ⅰ(37 cases),group Ⅱ(15 cases) and group Ⅲ(31 cases). Etidronate(400 mg/d) and placebo were given with intermittent cyclical therapy in group Ⅰ and group Ⅲ respectively, and alendronate(10 mg/d) was given continuously in groupⅡ for 9 months. Eeach group was given calcium agents(equal to elementary calcium 500 mg/d). Before and after treatment, the bone mineral density(BMD) was measured by dual energy X ray absorptiometry. The biochemical markers such as blood calcium, phosphate, alkaline phosphatase and urine calcium/creatinin were examined. Results After treatment the BMD of groupⅠ and groupⅡ wee increased obviously(P0.05). The BMD of group Ⅱ was increased more than that of groupⅠ(P
