How Dasatinib works
Dasatinib is a tyrosine kinase inhibitor.
It operates by hindering the function of multiple tyrosine kinases, enzymes that stimulate cancer cell growth. Its chief target is the abnormal BCR-ABL tyrosine kinase produced due to the Philadelphia chromosome abnormality. By obstructing these proteins, Dasatinib manages to slow or halt the growth and proliferation of leukaemia cells in the body.
