Biochem/physiol Actions

Risedronate sodium is a bisphosphonate bone resorption inhibitor. It has an affinity for hydroxyapatite crystals in bone and acts as an antiresorptive agent and is an inhibitor of farnesyl diphosphate (FPP) synthase, which results in downstream inhibition of osteoclast activity and reduced bone resorption and turnover. Risedronate sodium has been used to treat postmenopausal osteoporosis and Paget′s disease.

This randomized, double-blind study assessed the antifracture efficacy and safety of intermittent intravenous (IV) ibandronate versus oral daily risedronate in Japanese patients with primary osteoporosis. Ambulatory patients aged ≥60 years were randomized to receive 0.5 or 1 mg/month IV ibandronate

Alterations in resorption cavities and bone remodeling events during anti-resorptive treatment are believed to contribute to reductions in fracture risk. Here, we examine changes in the size of individual remodeling events associated with treatment with a selective estrogen receptor modulator

Bisphosphonates are widely used for the treatment of bone pathologies, mainly due to their ability to inhibit osteoclastic activity and thus bone resorption. Yet, their potential effect on bone formation is unclear. Our aim was to determine whether risedronate can

Low persistence with osteoporosis medication is associated with higher fracture risk. Previous studies estimated that 1-year persistence with osteoporosis medication is low. Our aim was to study persistence with osteoporosis medication among patients with long-term follow-up (to 5 years). The InterAction

This observational study showed that after 2 years, both risedronate and alendronate lowered the risk of hip and nonvertebral fractures compared with patients filling in a single bisphosphonate prescription. Post hoc analyses of the placebo-controlled trials suggested earlier effects for
