Answer

Calcium Metabolism Modifiers

Bisphosphonates are complementary to chemotherapy and hormone therapy because they may lessen the damage to bone from metastatic disease. Bisphosphonates inhibit osteoclast function and reduce the resorption of bone. An intravenous bisphosphonate should be used in combination with oral calcium citrate and vitamin D supplementation in bone metastasis, according to the National Comprehensive Cancer Network (NCCN) guidelines. [77]

Pamidronate (Aredia)

Pamidronate disodium is a bone resorption inhibitor that absorbs calcium phosphate crystals and prevents the dissolution of this mineral. It also inhibits osteoclast activity in the bone.

Zoledronic Acid (Zometa, Reclast)

Zoledronic acid inhibits bone resorption by acting on osteoclasts or osteoclast precursors. It may be superior to pamidronate in patients with lytic bone metastases.
