How does osteoclasts work
WebJan 3, 2024 · Interactions. 1. How it works. Reclast is a brand (trade) name for zoledronic acid which may be used to strengthen bones and to treat or prevent osteoporosis. Reclast (zoledronic acid) works by inhibiting osteoclasts which are responsible for breaking down and reabsorbing bone (by a process known as bone resorption). Webosteoclasts, which break down old bone osteoblasts, which build new bone This process is called bone remodelling and is very well controlled. There is a fine balance between the rates of bone breakdown and growth, which keeps bones strong and healthy. Denosumab works by targeting a protein called RANKL which controls the activity of osteoclasts.
