Is Bosutinib available in China?

Bosutinib (Bosutinib) is an oral targeted therapy drug, mainly used for the treatment of chronic myeloid leukemia (Chronic Myeloid Leukemia, CML). CML is a hematological malignancy caused by mutations in the BCR-ABL fusion gene in leukemia stem cells. The production of the BCR-ABL fusion gene is closely related to the presence of the Philadelphia chromosome.

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.

Bosutinib belongs to the second generation of tyrosine kinase inhibitors. Its unique feature lies in its inhibitory activity against multiple kinases, especially its high selectivity againstABLkinase. ABLkinase is a protein encoded by the BCR-ABL fusion gene and is a key factor in the excessive proliferation of leukemia cells in CML patients. The mechanism of action of bosutinib is mainly by inhibiting the activity of ABL kinase, thereby blocking the growth and division of abnormal leukemia cells.

Clinical research and practice have shown that bosutinib has achieved significant efficacy in the treatment ofCML. Patients usually observe improvements in routine blood parameters, reductions in spleen size, and relief of a range of clinical symptoms after taking bosutinib. This drug is a treatment option for CML, especially in patients who are resistant or intolerant to other treatment options.

It should be noted that the use of bosutinib is also accompanied by a series of possible side effects, including digestive system problems, fatigue, skin reactions, etc. Therefore, patients need to pay close attention to any symptoms of discomfort during use and make treatment adjustments under the guidance of a doctor.
