Message: | Strontium ranelate is registered as a prescription drug in more than 70 countries for the treatment of post-menopausal osteoporosis to reduce the risk of vertebral and hip fractures. In the United Kingdom, strontium ranelate is prescribed under the National Health Service as a medicine for the treatment of post menopausal osteoporosis.
2 major phase III clinical studies, SOTI (Spinal Osteoporosis Therapeutic Intervention) and TROPOS (Treatment of Peripheral Osteoporosis), were started in 2000 to investigate the efficacy of strontium ranelate in reducing vertebral fractures and peripheral fractures, including hip fractures.
In the 3 years results, reported in 2004, strontium ranelate showed significant reduction in vertebral fractures with 41% and hip fractures with 36% compared with patients treated with placebo.
The efficacy was sustained in 5 years data. The 5 years data confirmed that strontium ranelate can reduce the vertebral fractures significantly no matter the risk factors of the osteoporotic women have.
Strontium ranelate shows anti-fracture efficacy in very old elderly and osteopenic patients.
