Denosumab Injection: Uses, Dosage, Side effects, Brands & Price In India
What is Denosumab?
Denosumab is a targeted monoclonal antibody injection used to strengthen bones and prevent fractures, especially in patients with osteoporosis or cancer-related bone problems.
Unlike regular calcium medicines, Denosumab works at a cellular level to protect bones from damage.

How Denosumab Works

Denosumab blocks a protein (RANKL) responsible for activating these cells. - Result: -
