Dasatinib
In StockDasatinib is a prescription medicine used to treat certain types of blood cancers, including chronic myeloid leukemia (CML) and acute lymphoblastic leukemia (ALL). It belongs to the tyrosine kinase inhibitor class and works by blocking abnormal proteins that promote cancer cell growth. This action helps slow or stop the spread of cancer cells. Use as directed on the product label.
What is Dasatinib?
Dasatinib is a prescription medication used to treat certain types of blood cancers. It belongs to a drug class called **tyrosine kinase inhibitors (TKIs)**. These medicines block signals that tell cancer cells to grow.
Dasatinib is approved for:
* Chronic myeloid leukemia (CML)
* Philadelphia chromosome–positive acute lymphoblastic leukemia (Ph+ ALL)
It is used in adults and in some children, depending on the diagnosis and specialist guidance.
Available Forms and Strengths
Dasatinib is available as:
* Oral tablets in multiple strengths
It is not available as an injection or liquid formulation in most markets.
What is the Recommended Dosage of Dasatinib?
The dosage depends on:
* Type and stage of leukemia
* Age
* Body weight (especially in children)
* Liver function
* Response to treatment
Dasatinib is taken by mouth, usually once daily.
Important guidance:
* Take at the same time each day.
* Swallow tablets whole.
* Do not crush or split unless instructed by a specialist.
* Follow oncology specialist instructions carefully.
Dose adjustments may be needed based on lab results or side effects. Exact dosing must always be determined by a licensed oncologist.
How Dasatinib Works
Certain leukemia cells grow because of an abnormal protein signal. In CML and Ph+ ALL, this signal is linked to the **Philadelphia chromosome**.
Dasatinib works by:
* Blocking abnormal tyrosine kinase enzymes
* Stopping cancer cell growth signals
* Slowing or preventing cancer cell multiplication
It controls disease progression but does not permanently cure leukemia in most cases. Long-term treatment and regular monitoring are often required.
