Dasatinib is a tyrosine kinase inhibitor prescribed for the treatment of certain forms of chronic myeloid leukemia.
Dasatinib belongs to a class of medicines known as tyrosine-kinase inhibitors. It is designed to block specific signals that tell certain cancer cells to grow. In Hong Kong, dasatinib is available both as the brand name Sprycel and as generic dasatinib tablets.
The two main products that contain dasatinib are:
Both forms are taken by mouth and are approved for use in Hong Kong under the regulations of the Department of Health. The tablets are dispensed in packs that are convenient for short-term treatment cycles or longer maintenance therapy, depending on the prescribing information for each product.
Dasatinib is primarily used for blood-related cancers that involve the BCR-ABL protein. The main conditions include:
These diseases are driven by uncontrolled cell signalling, and dasatinib helps to restore normal control by targeting the underlying protein. The medication is usually prescribed for adult patients, but the exact age range depends on the individual product’s approved labeling.
Dasatinib blocks the activity of the BCR-ABL protein, which acts like a stuck accelerator in cancer cells. By turning off this signal, the drug slows or stops the growth of abnormal cells, allowing the body’s normal blood-forming system to recover. Effects are typically seen within days after the first dose, although full benefits may develop over several weeks of therapy.
Most people notice mild, temporary effects such as:
These reactions usually resolve on their own or with simple supportive care.

If any of these occur, immediate medical review is advised.
People who should take extra care when using dasatinib include:

Patients should review the full interaction list on the specific medication’s information sheet and discuss any over-the-counter products with their pharmacist.
Store dasatinib tablets at room temperature, away from excess moisture and direct sunlight. Keep the container tightly closed when not in use. Typical treatment periods vary; some patients use the drug for a few months, while others continue for many years as part of long-term disease management. Always follow the product-specific instructions that accompany each medication, as formulations and strengths differ between Sprycel and generic dasatinib.
Tyrosine-kinase inhibitor: A type of drug that blocks enzymes involved in cell growth signals, helping to control abnormal cell proliferation.
BCR-ABL protein: An abnormal protein produced by the Philadelphia chromosome that drives certain leukaemias.
