Zoledronic acid - Benefits, dosage and side effects

Zoledronic acid is a drug to treat calcium levels that are too high in the blood (hypercalcemia) due to cancer. In addition, zoledronic acid is also used in the treatment of postmenopausal osteoporosis, Paget's disease, or osteoporosis due to long-term use of corticosteroid drugs.

Hypercalcemia due to cancer occurs due to increased osteoclast activity, so bone resorption continues. Zoledronic acid will work by inhibiting the activity of osteoclasts in bone resorption.

With this way of working, calcium levels in the blood can be reduced and indirectly increase bone mass and strength.

This way of working will also reduce the risk of fractures. This drug is available in injectable form and should only be given by a doctor or medical officer under the supervision of a doctor.
