Where to buy Trastuzumab

Trastuzumab (Trastuzumab) is a targeted therapy drug, also known as a HER2 blocker. It is mainly used to treat HER2-positive breast cancer and stomach/esophageal cancer. HER2 (human epidermal growth factor receptor 2) is a protein that is involved in regulating cell growth and division under normal circumstances. However, in some tumors, abnormal increases in HER2 can lead to excessive growth and spread of tumor cells.

Trastuzumab is a humanized monoclonal antibody that inhibits the growth and signaling of tumor cells by binding to the HER2 receptor. It blocks the proliferation of HER2-positive tumor cells and promotes apoptosis (self-death) of these tumor cells. In addition, trastuzumab can also enhance the body's immune response and activate natural immune cells to attack tumor cells. Trastuzumab is usually given as an intravenous injection and needs to be used under the supervision of a professional medical provider. In the treatment of breast cancer and stomach/esophageal cancer, trastuzumab is often used in combination with chemotherapy drugs to increase the effectiveness of the treatment.

Trastuzumab is sold under the brand name Herceptin in China and has entered the scope of Class B medical insurance, but it may be limited to patients who meet the indications for this drug, such as patients with HER2-positive metastatic breast cancer and its adjuvant and neoadjuvant treatment or HER2-positive metastatic gastric cancer. The price is around 6,000 yuan. The original trastuzumab drug has also been launched overseas. The drug ingredients of domestic and foreign original drugs are basically the same. For specific prices and drug details, you can consult the medical consultant. There is currently no generic drug of trastuzumab on the market.
