Pamidronate is used to treat high blood calcium levels and certain bone problems (bone metastases/lesions) that may occur with some types of cancer. It is also used to treat a certain type of bone disease (Paget's disease) that causes abnormal and weak bones.
Pamidronate belongs to a class of drugs known as bisphosphonates. It works by slowing the release of calcium from bones to lower blood calcium levels, reducing the risk of broken bones (fractures) and reducing bone pain.
This medication is given by slow injection into a vein for at least 2 hours, but up to 24 hours, or as directed by your doctor.
The dosage is based on your medical condition, laboratory tests, and response to treatment. Your doctor will order blood tests to check your kidney function prior to each treatment with this medication. The usual maximum adult dose of this medication is 90 milligrams for a single dose.
