• 产品描述： Strontium Ranelate (S12911) is an antiosteoporotic agent that acts by reducing bone resorption and promoting bone formation, thereby inducing a positive bone balance. Strontium Ranelate can also activate the calcium-sensing receptor (CaSR) in non skeletal cells, resulting in the activation of inositol 1, 4, 5-triphosphate production and mitogen-activated protein kinase signaling

• 体内研究：
  Strontium Ranelate increases bone formation and decreased bone resorption, which results in increased bone mass in the vertebrae of intact adult mice. In intact adult rats, Strontium Ranelate also increases bone mass, as measured by dual-energy X-ray absorptiometry, in lumbar vertebra and femur, and this is confirmed by histological assessment of trabecular bone volume in the tibial metaphysis. Strontium Ranelate is found to decrease bone resorption and to increase bone formation in alveolar bone in normal adult monkeys (Macaca fascicularis), which exhibits extensive bone remodeling. In ovariectomized rats, short-term (3 months) treatment with Strontium Ranelate prevents trabecular bone loss induced by oestrogen deficiency, as demonstrated by bone ash, bone mineral content and histomorphometric analysis in the tibial metaphysis. This effect results from decreased bone resorption while bone formation was maintained. These beneficial effects of Strontium Ranelate on bone mass and microarchitecture in ovariectomized rats are confirmed in long-term experiments. In this long-term study (2 years), the increase in bone mass and microarchitecture induced by Strontium Ranelate results in a marked improvement in bone strength, supporting the beneficial effect of this drug on bone resistance.
