On 13 May 2013, Servier released a Direct Healthcare Professional Communication which stated that new restrictions for the use of strontium ranelate are now in place, as randomised trials have shown an increased risk of myocardial infarction.
[3] On 21 February 2014 the European Medicine Agency recommended that strontium ranelate remain available with restrictions relative to patients with existing heart disease.
[4] In 2017, a large study of over 280,000 British and Spanish patients found no increased risk of venous thromboembolism in users of strontium ranelate compared to alendronate.
[6] 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.
The 5 years data confirmed that strontium ranelate can reduce the vertebral fractures significantly no matter the risk factors of the osteoporotic women have.
[12][13] Strontium ranelate stimulates the calcium-sensing receptors and leads to the differentiation of pre-osteoblast to osteoblast which increases the bone formation.
Strontium ranelate also stimulates osteoblasts to secrete osteoprotegerin in inhibiting osteoclasts formed from pre-osteoclasts in relation to the RANKL system, which leads to the decrease of bone resorption.
