Strontium ranelate is composed of an organic moiety (ranelic acid) and of two atoms of stable nonradioactive strontium. In vitro, strontium ranelate increases collagen and noncollagenic proteins synthesis by mature osteoblast enriched cells. The effects of strontium ranelate on bone formation were confirmed as strontium ranelate enhanced pre-osteoblastic cell replication. The stimulation by strontium ranelate of the replication of osteoprogenitor cell and collagen, as well as noncollagenic protein synthesis in osteoblasts, provides substantial evidence to categorize strontium ranelate as a bone-forming agent. In the isolated rat osteoclast assay, a pre-incubation of bone slices with strontium ranelate induced a dose- dependent inhibition of the bone resorbing activity of treated rat osteoclast. Strontium ranelate also dose-dependently inhibited, in a chicken bone marrow culture, the expression of both carbonic anhydrase II and the alpha-subunit of the vitronectin receptor. These effects showing that strontium ranelate significantly affects bone resorption due to a direct and/or matrix-mediated inhibition of osteoclast activity and also inhibits osteoclasts differentiation, are compatible with the profile of an anti-resorptive drug. Pharmacological and clinical studies suggest that strontium ranelate optimizes bone resorption and bone formation, resulting in increased bone mass, which may be of great value in the treatment of osteoporosis. Strontium ranelate is approved by EMA for the treatment of severe osteoporosis in postmenopausal women and in adult men.

CNS Activity

Curator's Comment:: Strontium ranelate had no behavioural effects, no CNS toxicity nor CNS accumulation demonstrated with Strontium ranelate in the non-clinical studies.

Approved Use

Treatment of severe osteoporosis: - in postmenopausal women, - in adult men, at high risk of fracture, for whom treatment with other medicinal products approved for the treatment of osteoporosis is not possible due to, for example, contraindications or intolerance. In postmenopausal women, strontium ranelate reduces the risk of vertebral and hip fractures.

Sample Use Guides

The recommended dose is one sachet containing 2 g of strontium ranelate once daily by oral administration.
Route of Administration: Oral
Osteoblastic MC3TE-E1 cell cultures exposed to Strontium ranelate (SR) at 0.5 mM exhibited a decrease in both cell proliferation and cell viability in all time points assayed. High levels of protein and mRNA for Type I Collagen and Osteopontin were detected in cultures exposed to SR, particularly at 0.5 mM. SR allowed the expression of fibronectin in osteoblastic cell cultures as observed by epifluorescence analysis. The mineralized bone-like nodule formation was affected in a concentration-dependent manner by SR, with large bone-like nodules being detected in osteoblastic cell cultures exposed to SR at 0.5 mM.
