Strontium ranelate in postmenopausal osteoporosis treatment: a critical appraisal
نویسندگان
چکیده
Osteoporosis is a progressive and debilitating disease characterized by a massive bone loss with a deterioration of bone tissues, and a propensity for a fragility fracture. Strontium ranelate is the first antiosteoporotic treatment that has dual mode of action and simultaneously increases bone formation, while decreasing bone resorption, thus rebalancing bone turnover formation. Strontium ranelate rebalances bone turnover in favor of improved bone geometry, cortical thickness, trabecular bone morphology and intrinsic bone tissue quality, which translates into enhanced bone strength. This review describes the mechanism of the strontium ranelate action and its effects on bone mineral density, bone turnover, and osteoporotic fractures. The efficacy of strontium ranelate in postmenopausal osteoporosis treatment to reduce the risk of vertebral and hip fractures has been highlighted in several randomized, controlled trials. Treatment efficacy with strontium ranelate has been documented across a wide range of patient profiles: age, number of prevalent vertebral fractures, body mass index, and a family history of osteoporosis. Because strontium ranelate has a large spectrum of efficacy, it can be used to treat different subgroups of patients with postmenopausal osteoporosis. Strontium ranelate was shown to be relatively well tolerated and the safety aspects were good. Strontium ranelate should be considered as a first-line treatment for postmenopausal osteoporotic patients.

Efficacy of Strontium Ranelate in Combination with a D-Hormone Analog for the Treatment of Postmenopausal Osteoporosis
BACKGROUND Vitamin D supplements are recommended in individuals with vitamin D insufficiency and established osteoporosis to reduce risk of fracture and falling. Active vitamin D metabolites have been found to be more effective for fall prevention than native vitamin D. OBJECTIVES The aim of this study was to compare the efficacy of strontium ranelate in combination with alfacalcidol and stro...

This series of articles facilitated by the Cochrane Musculoskeletal Group (CMSG) aims to place the findings of recent Cochrane musculoskeletal reviews in a context immediately relevant to general practitioners. This article considers whether the availability of strontium ranelate affects the management of postmenopausal osteoporosis.
متن کاملA new contralateral atypical femoral fracture despite sequential therapy with teriparatide and strontium ranelate
Atypical femoral fractures (AFFs) are a rare association of anti-resorptive therapy for osteoporosis. Limited evidence-based management guidelines on their optimal treatment exist, with observational studies suggesting a role for teriparatide (TPTD) in AFF healing. We report a case of a 65-year-old woman with postmenopausal osteoporosis who sustained an AFF following long-term bisphosphonate th...
