Physical description & handling notes

• Solid
• Pamidronic acid is a second generation, nitrogen containing bisphosphonate that inhibits osteoclast mediated bone loss It has a wide therapeutic index and a long duration of action as it can be given every 3-4 weeks for certain indications. Patients should be counselled regarding the risk of elevated blood urea nitrogen, renal tubular necrosis, and nephrotoxicity.

Documented Uses

• Use (kg; approx.) in Germany (2009): >10
• Consumption (g per capita; approx.) in Germany (2009): 0.000122
• Consumption (g per capita) in the USA (2002): 5.1e-05
• Pamidronate is in a class of drugs called bisphosphonates. Pamidronate reduces breakdown of the bones. Pamidronate is used in the treatment of Paget's disease of bone; to reduce high levels of calcium in the blood associated with malignancy (cancer); and to reduce the breakdown of bone due to metastases of breast cancer or multiple myeloma. For the treatment of moderate or severe hypercalcemia associated with malignancy
• Pamidronate is indicated to treat moderate to severe hypercalcemia of malignancy, moderate to severe Paget's disease of bone, osteolytic bone metastases of breast cancer, and osteolytic lesions of multiple myeloma.
• Pamidronate belongs to the drug class known as bisphosphonates, whose therapeutic value stems from their ability to inhibit osteoclast-mediated bone resorption.
