Is Trastuzumab domestically produced or imported?

Trastuzumab (Trastuzumab) is either domestically produced or imported. The ingredients of the two drugs are basically the same. Their prices and specifications may be different, but they can both be used to treat cancers with prescription information. Trastuzumab targets human epidermal growth factor receptor 2 (HER2), also known as ERBB2. HER2 belongs to the tyrosine kinase receptor family, which is involved in signaling pathways that regulate cell growth and differentiation under normal circumstances. However, in some breast cancer patients, the HER2 gene is overexpressed or mutated, leading to the development of HER2-positive breast cancer.

Trastuzumab bindsHER2, forming a complex on the patient's tumor cells and inhibiting the activity of HER2. This inhibits the growth, division and spread of HER2-positive breast cancer cells, thereby halting the cancer's progression. By targeting the mechanism of action of the specific molecular target HER2, trastuzumab has become one of the key drugs in the treatment of HER2-positive breast cancer, helping patients prolong survival and improve treatment effects.

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.
