Is Bosutinib a targeted drug or a chemotherapy drug?

Bosutinib (Bosutinib) is a targeted therapy drug rather than a traditional chemotherapy drug. It belongs to the category of tyrosine kinase inhibitors, a class of drugs specifically designed to interfere with abnormal signaling pathways, specifically targeting abnormal kinase activity present in leukemia cells.

In leukemia, specific genetic mutations can cause cells to produce abnormal proteins, such as theBCR-ABLfusion protein, which is a common mutation in patients with chronic myelogenous leukemia (CML). The mechanism of action of bosutinib is mainly focused on inhibiting the ABL kinase activity in this abnormal protein. ABLkinase is a tyrosine kinase, and its overactivation is related to the abnormal proliferation and survival of leukemia cells.

Compared with traditional chemotherapy drugs, targeted therapy drugs are more selective and can more accurately interfere with the survival and proliferation of cancer cells while reducing damage to normal cells. This makes targeted therapy an important treatment option in certain cancer types.

Bosutinib is commonly used in clinical applications in patients with chronic myelogenous leukemia, especially those who are resistant or intolerant to other treatment options. Its targeting effect helps control the development of leukemia, improves patient survival rates, and its side effects are more controllable than traditional chemotherapy drugs.

Bosutinib is not yet available in China, so patients cannot purchase it domestically and need to purchase it through overseas channels. There are original drugs and generic drugs of bosutinib abroad. The original drugs include the Turkish original drug and the European version of the original drug. The Turkish version of the original drug costs about 2,000 to 3,000 yuan, and the European version of the original drug costs about 30,000 yuan. In addition, there are cheaper generic drugs, which cost more than one thousand yuan, and the ingredients of the original drugs and generic drugs are basically the same.
