What Pamidronate Disodium is and what it is used for

Pamidronate Disodium 3mg/ml concentrate for solution for infusion contains active substance 3 mg of
pamidronate disodium equivalent to 2.53mg of pamidronic acid.
This is one of a group of medicines called bisphosphonates which can help to regulate the amount of
calcium in the blood.
High blood calcium levels (hypercalcaemia) occur in a number of conditions, including some types of
cancer. Often, hypercalcaemia is caused by the release of calcium from bones. Pamidronate Disodium
sticks to bones and helps to reduce the release of calcium into the blood. If untreated, hypercalcaemia can
cause symptoms such as nausea, tiredness and confusion.
Pamidronate Disodium is used to treat high blood calcium levels caused by some cancers. In some
patients with cancer, it is also used to treat bone disease and to help relieve bone pain.
Pamidronate Disodium is also used to treat Paget’s disease.
