Imatinib is a protein-tyrosine kinase inhibitor that blocks the abnormal protein that signals cancer cells to multiply. It is indicated for chronic myeloid leukaemia and gastrointestinal stromal tumours. This ingredient is available in high-quality generic formulations, providing vital access to advanced oncology care. Our platform ensures UK patients can find verified treatments containing Imatinib with ease.
Imatinib belongs to a class of medicines called tyrosine-kinase inhibitors. It works by blocking specific enzymes that help certain abnormal cells grow and spread. Imatinib is best known for being the active ingredient in the cancer medicine Gleevec.
The most widely prescribed product that contains imatinib in the UK is Gleevec (generic name: imatinib). Gleevec is available as oral tablets, typically in strengths of 100 mg and 400 mg. The tablets are colour-coded and may be supplied as a brand-name product (Gleevec) or as a generic version that contains the same active ingredient. Both forms are approved by the Medicines and Healthcare products Regulatory Agency (MHRA) for use in the UK.
Imatinib is primarily used in the treatment of several types of blood-forming (haematological) cancers and some solid tumours. The main conditions include:
These diseases involve abnormal cell signalling pathways that rely on the enzymes imatinib blocks. By interfering with those pathways, imatinib helps to control the growth of malignant cells.
Imatinib targets specific proteins called tyrosine kinases. These proteins act like switches that tell cells when to grow, divide, or die. In the cancers listed above, the switches are stuck in the “on” position, leading to uncontrolled cell proliferation. Imatinib binds to the switch and keeps it turned off, which slows or stops the growth of the abnormal cells. This action usually begins to have an effect within a few weeks of starting therapy.
People taking imatinib-containing medicines often notice mild, temporary effects such as:
These symptoms typically improve with continued use or by adjusting everyday habits, but they should be monitored.
Although rare, some reactions require immediate medical attention:
If any of these occur, seek urgent care.
Imatinib should be used carefully in certain groups:
Imatinib can interact with other medicines and some lifestyle factors:
For a complete list of possible interactions, refer to the information provided with each specific product.
Store Gleevec tablets at room temperature, away from excess moisture and direct sunlight. Keep the medication out of reach of children. Treatment length varies - some patients use it for months, others for several years, depending on the condition being managed. Always follow the instructions that come with your particular product, as strengths and dosing schedules differ between brands and formulations.
For detailed usage, dosing, and administration, refer to the specific medication’s information.
