Aredia (pamidronate)

Aredia (pamidronate) is an intravenous bisphosphonate drug made by Novartis Pharmaceuticals Corporation, and is used to treat hypercalcemia (excess calcium in the blood) that may occur with some types of cancer. Aredia is also used to treat bone metastasis, or the spread of cancer, and Paget's disease, a medical condition in which the body replaces healthy bones with weak bones.

Why Prescribed

Aredia is a medicine that inhibits bone resorption and is used for treating high calcium content in blood associated with cancer, and sometimes in bone pain palliation and to control osteoporosis prompted by hormonal therapy.

Warnings and Alerts

In September 2004, Novartis Pharmaceuticals and the FDA notified dental healthcare professionals of the occurrence of Osteonecrosis of the Jaw (ONJ) observed in cancer patients receiving treatment with intravenous bisphosphonates, such as Aredia. The revised prescribing information that followed recommended that cancer patients receive a dental examination prior to taking Aredia, and that they avoid invasive dental procedures while on this medication.

Drug Contraindications

Aredia is contraindicated in patients with clinically significant hypersensitivity to bisphosphonates, and those patients undergoing extensive dental procedures.

FAQ's

What is the most important information I should know about Aredia?

Do not use Aredia without first talking to your doctor if you have had an allergic reaction to pamidronate or another similar medication such as alendronate (Fosamax), etidronate (Didronel), risedronate (Actonel), tiludronate (Skelid), or zoledronic acid (Zometa).

A dental examination with appropriate preventive dentistry should be considered before starting treatment with Aredia. This is especially important if you:

• Have poor dental health
• Have cancer
• Are receiving chemotherapy
• Are taking corticosteroids.

How do cancer cells affect bones?

Before using Aranesp, tell your doctor if you have:

It is possible in some patients for cancer cells to spread from its original site, i.e. the breast(s) to the bones. The cancer cells then grow into small tumors which release chemicals that upset the normal balance between bone formation (osteoblast cells) and bone reabsorption (osteoclast cells).

These chemicals stimulate osteoclasts to excessively reabsorb bone, release calcium into the blood stream, and reduce bone density, leading to holes in the bones and weakness. Weak bones lead to bone pain and fracture.

What is Osteonecrosis of the Jaw?

Osteonecrosis of the Jaw (ONJ), also known as ‘dead jaw’ is a medical condition in which the jawbone partially disintegrates and dies. ONJ may cause severe pain, loose teeth, exposed bone, loss of function, and disfigurement.

What should I do if I think I have been injured as a result of taking Aredia?

While all medications have certain, anticipated side effects, a drug manufacturer has a duty to inform physicians adequately regarding the known risks associated with its drugs. If a manufacturer fails to do so, it can be held responsible to patients who are injured as the result of inadequate warnings, under a legal theory known as "product liability."

If you or a loved one has experienced health complications while taking Aredia, you should contact your doctor immediately. You may also wish to contact an experienced drug litigation attorney to discuss the legal options available to you.
