Pamidronate disodium

About pamidronate disodium

Pamidronate disodium, a bisphosphonate, is prescribed for a number of different problems which affect bones. It can be prescribed to ease bone pain or to reduce hypercalcaemia associated with some cancers. It is also prescribed for people with Maladie osseuse de Paget to prevent bone damage.

In some cancers there can be an excessive breakdown of bone. As this happens, calcium is lost from the bone and seeps into the blood, leading to higher than normal levels of calcium in the blood. This is called hypercalcaemia. Pamidronate disodium binds to bone and reduces the rate at which it is broken down. This helps strengthen bones by preventing the loss of calcium and this reduces the high levels of calcium in the blood.

In Paget's disease of bone, pamidronate disodium works on bones to make them stronger and help prevent bone thickening. This helps ease symptoms such as pain, bone damage and fracture.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start treatment it is important that your doctor knows:

• Si vous êtes enceinte ou si vous allaitez.

• If you are due to have any dental treatment in the near future, or if you have pas recently had a dental check-up.

• Si vous avez une maladie cardiaque.

• If you have any problems with the way your kidneys work, or the way your liver works.

• If you have ever had any surgery on your thyroid gland.
