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.
