Imatinib
Imatinib (typically known by the brand Glivec) is a targeted therapy medication used primarily for specific types of blood cancer and digestive tract tumours. Gleevec is available as a central option, an essential film-coated tablet formulation. This medication is widely utilised in the management of complex oncological conditions.
Key points
- Treats chronic myeloid leukaemia and gastrointestinal stromal tumour by targeting the tyrosine kinase enzymes that drive their growth.
- Sold as the originator Glivec alongside generic versions such as Gleevec, both formulated as film-coated tablets.
- Reported reactions include fluid retention, digestive upset, skin reactions and altered blood cell counts, which need monitoring.
What is Imatinib?
Imatinib belongs to a class of medications called tyrosine kinase inhibitors. These compounds work by targeting specific proteins that signal cells to divide and multiply. By blocking these signals, the medication may slow or halt the progression of certain cell abnormalities. Because Imatinib requires precise formulation to ensure appropriate absorption, it is manufactured as a film-coated tablet to maintain stability.
What Imatinib is used for
This medication acts as a specific therapeutic intervention. It is used in the treatment of Chronic Myeloid Leukaemia, a type of blood cancer where bone marrow makes too many white blood cells. It is also used to address Gastrointestinal Stromal Tumour, a rare type of tumour that develops in the digestive tract. These applications require ongoing monitoring carried out by clinical teams.
How Imatinib works
Imatinib functions as a molecular level “switch” that turns off specific enzymes responsible for abnormal cell proliferation. In healthy cells, these enzymes are tightly regulated. In the conditions noted above, these enzymes may become overactive. The medication binds to these specific protein sites, preventing the enzymes from activating, which can reduce the number of affected cells over time.
Imatinib brands and forms
The range of medicines for this therapy involves the originator brand, Glivec, and various generic versions such as Gleevec. While the active compound remains the same across these products, generics provide necessary options for patients. This medication is part of broader Oncology Support strategies. It is standardly available in film-coated tablet form to ensure consistency in how the body processes the medication.

What is imatinib used for?
Imatinib is used to treat chronic myeloid leukaemia, a blood cancer in which the bone marrow makes too many white blood cells. It is also used to treat gastrointestinal stromal tumour, a rare tumour that develops in the digestive tract. These uses need ongoing monitoring by clinical teams.
How does imatinib work?
Imatinib is a tyrosine kinase inhibitor. It binds to specific protein sites and stops certain enzymes from activating, which may slow or halt the growth of abnormal cells. In this way it can reduce the number of affected cells over time.
How long does imatinib take to work?
Imatinib starts working within 2 to 4 hours of taking a dose, and its effects last around 24 hours. Any reduction in affected cells happens gradually over time rather than straight away.
What are the side effects of imatinib?
Common reports include nausea, muscle cramps, oedema and fatigue, along with digestive upset, skin reactions and changes in blood cell counts. Some people get diarrhoea, headache or neutropaenia. Serious reactions such as congestive heart failure or severe gastrointestinal haemorrhage need immediate medical attention, so speak to your doctor or pharmacist if you notice anything unusual.
Can imatinib be taken with other medicines?
Some other substances, including other tablets, vitamins and herbal supplements, can change how imatinib works in your body. Known interactions include ketoconazole, warfarin and grapefruit. Tell your doctor or pharmacist about everything you are taking, because additive or counteracting effects can occur.
Who should not take imatinib?
Imatinib is not suitable for anyone with a hypersensitivity to imatinib. Before starting it, tell your care team about any history of liver, kidney or heart conditions so they can check whether it suits your diagnosis. Ask your doctor or pharmacist if you are unsure.
