What Is Zoledronic Acid?

Zoledronic acid is a nitrogen-containing bisphosphonate that inhibits osteoclast-mediated bone resorption. It is administered intravenously, offering a convenient dosing schedule compared to oral options. Approved by FDA in 2001, it is used for various indications:

• Postmenopausal osteoporosis
• Hypercalcemia of malignancy
• Bone metastases in cancer (e.g., breast, prostate, multiple myeloma)
• Paget’s disease of bone

Active formulations include:	Brand Name	Manufacturer	Indications	Dosing Schedule
Zometa	Novartis	Cancer-related bone disease	4 mg IV every 3–4 weeks
Reclast	Novartis	Osteoporosis, Paget's	5 mg IV once yearly
