Imatinib
About Imatinib
Imatinib belongs to a class of drugs known as 'anti-cancer medication', primarily used to treat various types of cancer. It is used to treat cancer of the blood (chronic myeloid leukaemia and acute lymphocytic leukaemia) and gastrointestinal stromal tumour. Cancer is a genetic change in which the cells divide uncontrollably and spread into surrounding tissues. There are more than 100 types of cancer, including blood cancer, lung cancer, breast cancer, etc.
Imatinib contains Imatinib, which is primarily used to treat cancer. It works by inhibiting an enzyme responsible for cancer cell proliferation and induces cell death (apoptosis). As a result, the growth and spread of cancer cells are stopped or slowed down.
You are advised to take Imatinib for as long as your doctor has prescribed it for you, depending upon your medical condition. In some cases, you may experience nausea, vomiting, oedema, fatigue, muscle cramps, musculoskeletal pain, diarrhoea, rash, and abdominal pain. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.
Do not take Imatinib if you are allergic to any of its ingredients. While taking Imatinib, you might become more sensitive to sunlight, so it is important to protect your skin with a high sun protection factor (SPF). Regular blood tests are required to monitor liver function and blood cells in the blood while taking Imatinib. Imatinib can cause swelling and water retention, so if you have unexpected rapid weight gain, please consult your doctor. If you ever had a hepatitis B infection, please tell your doctor before starting Imatinib as it can make hepatitis B active again.

Patients Concern
Disease/Condition Glossary
Cancer: It is a genetic change in which our cells divide uncontrollably and spread into surrounding tissues. There are two types of cancer: benign (localized) and metastatic (spread to the whole body). There are more than 100 types of cancer, including blood cancer, lung cancer, breast cancer, etc. Cancer growth can be prevented by chemotherapy (by strong antibiotics), radiation and stem cell therapy. To date, there is no cure for cancer.
Chronic myeloid leukaemia: It is a type of cancer that affects the white blood cells and tends to progress slowly over many years. It can occur at any age but is most common in adults around 60-65.
Acute lymphocytic leukaemia: A type of leukaemia (blood cancer) that comes on quickly and is fast-growing. In acute lymphoblastic leukaemia, there are too many lymphoblasts (immature white blood cells) in the blood and bone marrow.
A gastrointestinal stromal tumour (GIST): It is a type of tumour in the stomach or small intestine. The tumours develop into the specialized cells called interstitial cells of Cajal (ICCs).
