The Benefits of Strontium in the treatment for Osteoporosis Questioned

Strontium ranelate for the treatment of osteoporosis is useful, but changes in bone// mineral density need careful interpretation. Nowadays the main treatment options are anti-resorptive agents that prevent bone breakdown. For patients with previous fractures, treatment with an anabolic agent ...

Osteoporosis may be treated with strontium ranelate

UK had licensed the use of strontium ranelate to be used for treating patients with osteoporosis//, but scientists caution that before prescribing the drug it is important to observe the changes in the bone mineral density. A study in the British Medical Journal has said that the drug strontiu...
