How Does it Work?
Trastuzumab is not a traditional chemotherapy medication; it is in a class of medications called monoclonal antibodies, a type of targeted therapy.
Traditional chemotherapy drugs identify cancer cells by their rapid rate of reproduction, and then attack those cells. Unfortunately, there are many cells in our bodies that normally reproduce rapidly and these cells are also affected by traditional chemotherapy drugs, resulting in many unpleasant side effects.
Trastuzumab is designed to work differently. Instead of attacking rapidly reproducing cells, it targets the HER2/neu receptor on cancer cells .and prevents those cells from multiplying. It may also act by stimulating your own immune system to attack the cancer cells to which the trastuzumab has attached.
