Trastuzumab, commonly known under the brand name Herceptin, is a monoclonal antibody used in the treatment of certain types of breast cancer. It is pronounced as tras-TOO-zoo-mab and belongs to the drug class of HER2/neu receptor antagonists. Trastuzumab is available by prescription and is typically administered through intravenous infusion under the supervision of a healthcare professional. The drug works by targeting the HER2 protein, which can promote the growth of cancer cells.
What conditions or symptoms is Trastuzumab used to treat?
Trastuzumab is primarily used to treat HER2-positive breast cancer, which is a form of cancer that tests positive for a protein called human epidermal growth factor receptor 2. This protein promotes the growth of cancer cells. In addition to breast cancer, Trastuzumab is also used in the treatment of metastatic stomach cancer. If you are experiencing symptoms such as persistent pain, swelling, or unusual lumps, it is important to consult a healthcare provider.

How does Trastuzumab work in the body?
Trastuzumab works by binding to the HER2 receptor on the surface of cancer cells. This binding inhibits the proliferation of cancer cells by blocking the signals that promote cell growth. Additionally, Trastuzumab can recruit immune cells to attack the cancer cells, enhancing the body's immune response against the tumor. By targeting the HER2 protein, Trastuzumab helps to slow down or stop the growth of cancer cells, thereby aiding in the treatment of HER2-positive cancers.
In what forms is Trastuzumab available?
Trastuzumab is available in several dosage forms, primarily as a lyophilized powder for injection. This powder is reconstituted and administered intravenously. The drug is typically given in a healthcare setting, such as a hospital or clinic, where medical professionals can monitor the infusion process. The dosage and frequency of administration depend on the specific condition being treated and the patient's response to therapy.
What are the most common side effects of Trastuzumab?
Common side effects of Trastuzumab include fever, nausea, vomiting, diarrhea, and headache. Patients may also experience fatigue, rash, and infections due to the immunosuppressive nature of the drug.
