Trastuzumab is a medication used in the treatment of certain types of cancer, particularly HER2-positive breast cancer and stomach cancer. It is a targeted therapy that specifically targets the HER2 protein, which is overexpressed in some cancer cells.
Trastuzumab is typically administered as an intravenous (IV) injection. The drug works by binding to the HER2 receptors on cancer cells, inhibiting their growth, and signaling pathways that promote cancer cell proliferation.
The dosing and schedule of trastuzumab injections can vary depending on the specific cancer being treated and the treatment plan prescribed by the oncologist. It is essential to follow the healthcare provider's instructions regarding the dosage, timing, and duration of treatment.
