How strontium ranelate, via opposite effects on bone resorption and formation, prevents osteoporosis



Oestrogen deficiency increases the rate of bone remodelling which, in association with a negative remodelling balance (resorption exceeding formation), results in impaired bone architecture, mass and strength. Current anti-osteoporotic drugs act on bone remodelling by inhibiting bone resorption or by promoting its formation. An alternative therapeutic approach is based on the concept of inducing opposite effects on bone resorption and formation. One therapeutic agent, strontium ranelate, was shown to induce opposite effects on bone resorption and formation in pre-clinical studies and to reduce fracture risk in postmenopausal osteoporotic patients. How strontium ranelate acts to improve bone strength in humans remains a matter of debate, however. This review of the most recent pre-clinical and clinical studies is a critical analysis of strontium ranelate’s action on bone resorption and formation and how it increases bone mass, microarchitecture and strength in postmenopausal osteoporotic women.
