Research Context

Research context compiled from published sources

How does Alendronic Acid work?

Binds to hydroxyapatite in bone, inhibiting osteoclast-mediated bone resorption. Osteoclasts take up the bisphosphonate during bone resorption and undergo apoptosis. This shifts the balance of bone remodelling in favour of osteoblast-mediated bone formation, increasing bone mineral density over time.

Research Depth

Well Studied

Extensive human research over many years, including randomized controlled trials.
