Abstract
Early postmenopausal women (n = 160) were randomised to receive placebo or strontium ranelate (SR) 125 mg/day, 500 mg/day or 1 g/day for 2 years (40 participants per group). All participants received calcium 500 mg/day. The primary efficacy parameter was the percent variation in lumbar bone mineral density (BMD), measured using dual-energy X-ray absorptiometry. Secondary efficacy criteria included hip BMD and biochemical markers of bone turnover. At month 24, SR 1 g/day significantly increased lumbar BMD compared with placebo [mean (SD) +5.53% (5.12); ppppp = 0.048). No effect on markers of bone resorption was observed. SR was as well tolerated as placebo. The minimum does at which SR is effective in preventing bone loss in early postmenopausal non-osteoporotic women is therefore 1 g/day.Keywords
