Indications
Zoldix is used to treat high calcium levels in blood caused by cancer. Zoldix is also used for bone problems related to cancer, including bone metastases, and osteolytic lesions from multiple myeloma. Zoldix helps treat osteoporosis caused by corticosteroids and increases bone mass in men with osteoporosis. Zoldix is used in postmenopausal women for osteoporosis and Paget’s disease of the bone. Zoldix can also prevent postmenopausal osteoporosis.
Pharmacology
Zoldix belongs to a group of medications called bisphosphonates, which work mainly on the bones. Zoldix helps stop bone breakdown by blocking the activity of bone cells called osteoclasts. After Zoldix is given through an IV, Zoldix quickly moves to the bones. Zoldix works by targeting an enzyme that plays a role in bone breakdown. Zoldix also has anti-cancer effects, helps reduce pain, and prevents the growth of blood vessels that supply tumors. Zoldix does not build up in the blood after repeated doses and is excreted unchanged through the kidneys.
Dosage & Administration
Hypercalcemia of malignancy: The recommended dose is 4 mg given as an intravenous infusion. If calcium levels do not return to normal, retreatment can be considered after 7 days.
Multiple myeloma and bone metastases: The recommended dose is 4 mg every 3-4 weeks. Patients should also take a daily calcium supplement (500 mg) and Vitamin D (400 IU).
Interaction
Zoldix can be safely used with common cancer treatments, diuretics, antibiotics, and pain relievers. However, caution is advised when used with aminoglycosides, as they may cause prolonged low calcium levels. In patients with multiple myeloma, using Zoldix with thalidomide may increase the risk of kidney problems. When used with loop diuretics, Zoldix can increase the risk of low calcium levels. Caution is also needed with other drugs that may harm the kidneys.
Contraindications
Zoldix should not be used by people who are allergic to Zoldix or any of its ingredients, or by those with severe kidney problems (creatinine clearance <30 ml/min). Zoldix is not recommended during pregnancy or while breastfeeding.

Pregnancy & Lactation

Precautions & Warnings
Patients should be well-hydrated before receiving Zoldix, especially the elderly or those on diuretics. They should drink two glasses of water before and after the infusion. Blood calcium, phosphate, magnesium, potassium, and kidney function should be monitored regularly. If low calcium, phosphate, or magnesium levels occur, short-term supplements may be needed.
