Strontium Ranelate – A “dual action bone agent” (DABA)

One should know about Strontium :

Strontium, which has the atomic symbol Sr and the atomic number 38, belongs to the group II in the periodic table of the elements, just beneath calcium. Because its nucleus is very nearly the same size as that of calcium, the body easily takes up strontium and incorporates it into bones and tooth enamel in the place of calcium. Surprisingly, this is not a health problem and in fact, it can provide a health benefit. For example, in clinical trials, the drug strontium ranelate was found to aid bone growth, increase bone density, and lessen vertebral, peripheral, and hip fractures in women.

What is Strontium Ranelate :

Strontium ranelate is an antiosteoporotic agent which both increases bone formation and reduces bone resorption, resulting in a rebalance of bone turnover in favor of bone formation. This is similar to the effects of choline stabilized orthosilicic acid.

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.

Contra indications : API Apollo

Strontium ranelate is contraindicated in hypersensitivity to the active substance or to any of the excipients. It is not recommended in patients with severe renal disease, i.e. creatinine clearance below 30 mL/min due to lack of data. Precaution is advised in patients at increased risk of venous thromboembolism (VTE), including patients with a history of VTE. Precaution is advised in patients with phenylketonuria, as strontium ranelate contains phenylalanine. Precaution as it interferes with colorimetric measurements of calcium in blood and urine.
