How Bortezomib for Injection works

Bortezomib for injection (Bortezomib) is a targeted therapy drug mainly used to treat malignant tumors such as multiple myeloma and certain non-Hodgkin lymphomas. Its mechanism and effects include the following aspects:

1.Proteasome inhibition: Bortezomib is a proteasome inhibitor that acts on the proteasome structure in cells. Proteasomes are special structures within cells that are responsible for breaking down and degrading proteins. This process is important for maintaining normal cell function and metabolism. However, cancer cells usually require more proteins to support their abnormal growth and proliferation, so they are highly dependent on the activity of the proteasome. Bortezomib alters the intracellular protein degradation process by inhibiting the function of the proteasome.

2.Protein accumulation: By inhibiting the activity of the proteasome, bortezomib causes the accumulation of proteins in cancer cells. These accumulated proteins are important for the survival and proliferation of cancer cells. Therefore, the effect of bortezomib can be understood as blocking the protein degradation mechanism of cancer cells, causing a large amount of protein to accumulate inside the cancer cells.

3.Apoptosis: Bortezomib ultimately triggers apoptosis (cell death) in cancer cells due to protein accumulation and other intracellular changes. This is a key therapeutic effect because it reduces the number of cancer cells, thereby slowing tumor growth and spread.

4.Targeted therapy: Bortezomib is a targeted therapy drug with a relatively specific mechanism of action that mainly affects cancer cells and has a relatively small impact on normal cells. This is an advantage over traditional broad-spectrum chemotherapy drugs, which are often toxic to normal cells as well.

Bortezomib is already on the market in China and has been included in medical insurance. Patients can purchase it domestically at a price of around 3,000 to 4,000 yuan. Please consult the local hospital pharmacy for specific prices and reimbursement policies. The cheaper ones abroad are mainly Indian generic drugs, which cost around 1,000 yuan and have basically the same ingredients as the domestic bortezomib drug.
