Pertuzumab is an anti-cancer or cytotoxic chemotherapy drug used for the treatment of HER2-positive breast cancer. This is a type of cancer that tests positive for a protein called human epidermal growth factor receptor 2 (HER2). In which it promotes the growth of cancer cells. Breast cancer symptoms vary widely; from lumps to swelling to skin changes and many breast cancers have no obvious symptoms at all. Some signs and symptoms may include:
- Skin irritation or dimpling
- Swelling of all or part of the breast
- Nipple pain or the nipple turning inward
- Breast pain
- A nipple discharge other than breast milk
- Scaliness, redness, or thickening of the nipple orbreast skin
- A lump in the underarm area
These changes can also be signsof less serious conditions that are not cancerous. It’s important to get anybreast changes checked out promptly by a doctor. HER2 is present in excessiveamounts on the surface of some cancer cells. Its presence stimulates the growthof these cancer cells.
This medication is in the classof medications called monoclonal antibodies. This blocks the growth and spreadof cancer. They target and interfere with processes in the cells that causecancer to grow. This binds to a different area of the HER2 protein. Pertuzumab injectionis a sterile, clear to slightly opalescent, and colorless to pale brown liquidfor intravenous use. Each single-use vial contains 420 mg of Pertuzumab at aconcentration of 30mg/mL.
Howdoes Pertuzumab work?
Pertuzumab works in a similar wayto the natural antibodies produced by our immune system. Our natural antibodiesrecognize foreign invaders and bind to them. This helps our immune systems toattack them and protect us from infections. Monoclonal antibodies like thisdrug are effective in attacking cancer cells.
This drug specifically recognizesand binds to the HER2 protein on breast cancer cells. This stops the cancercells from growing and multiplying. Pertuzumab also triggers the immune systemto attack and kill the cancerous cells. This prescription only works in peoplewho have high levels of the HER2 protein. There may be various tests to measurethe levels of HER2.
