Trastuzumab, marketed under the brand name Herceptin, is a medication used in the treatment of certain types of cancer, primarily breast cancer. It is a monoclonal antibody that targets a specific protein called human epidermal growth factor receptor 2 (HER2). HER2 is a protein that promotes the growth of cancer cells, and in some cases, its overexpression is associated with aggressive forms of breast cancer.
Trastuzumab is primarily used for the following purposes:
It’s important to note that trastuzumab is typically prescribed by oncologists and administered under their supervision. The treatment regimen, dosage, and duration can vary depending on the specific type and stage of cancer, as well as individual patient factors. Trastuzumab has shown significant benefits in improving the outcomes for individuals with HER2-positive breast cancer and certain types of stomach cancer. However, like all medications, it can have side effects, and its use should be carefully monitored by healthcare professionals.
