How it works
Reclast (Zoledronate) is a bisphosphonate. It slows down osteoclasts, the cells that break down bone. This results in greater bone mass and lowers the possibility of fractures.Prolia (Denosumab) is a monoclonal antibody. It blocks a protein that sends signals to break down your bones, and therefore prevents bone loss.
