What is Dasatinib Used For?
Dasatinib is a medication primarily used to manage certain types of cancers, especially those affecting the blood and bone marrow. Specifically, it is used to treat chronic myeloid leukemia (CML) and acute lymphoblastic leukemia (ALL) when these are Philadelphia chromosome-positive (Ph+). Dasatinib works by targeting and inhibiting a protein known as BCR-ABL, which contributes to the uncontrolled growth of cancer cells. By blocking this protein, Dasatinib helps to prevent the spread of cancer cells, offering a way to manage and control the disease effectively.How Does Dasatinib Work?
Dasatinib belongs to a class of drugs known as tyrosine kinase inhibitors. These drugs block specific proteins that signal cancer cells to grow. In the case of Philadelphia chromosome-positive leukemias, the abnormal protein BCR-ABL is present, which makes the cancer cells multiply rapidly. Dasatinib inhibits the activity of BCR-ABL, slowing down or stopping the progression of the disease.How to Take Dasatinib
