1. What Imatinib Krka d.d. is and what it is used for
Imatinib Krka d.d. is a medicine that contains the active substance imatinib. This medicine works by inhibiting the growth of abnormal cells in the diseases described below. These include some types of cancer.
Imatinib is a treatment for adults and children for:
- Chronic myeloid leukemia (CML).Leukemia is a cancer of the white blood cells. These white blood cells normally help the body fight infections. Chronic myeloid leukemia is a type of leukemia in which certain abnormal white blood cells (called myeloid cells) start to grow out of control.
- Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL).Leukemia is a cancer of the white blood cells. These white blood cells normally help the body fight infections. Acute lymphoblastic leukemia is a type of leukemia in which certain abnormal white blood cells (called lymphoblasts) start to grow out of control. Imatinib inhibits the growth of these cells.
Imatinib is also a treatment for adults for:
- Mycloproliferative disorders (MPD).These are a group of diseases of the blood in which some blood cells start to grow out of control. Imatinib inhibits the growth of these cells in a certain subtype of these diseases.
- Hypereosinophilic syndrome (HES) and/or chronic eosinophilic leukemia (CEL).These are diseases of the blood in which certain blood cells (called eosinophils) start to grow out of control. Imatinib inhibits the growth of these cells in a certain subtype of these diseases.
- Gastrointestinal stromal tumors (GISTs).GIST is a cancer of the stomach and intestine. It originates from uncontrolled cell growth of the supporting tissues of these organs.
- Dermatofibrosarcoma protuberans (DFSP).DFSP is a cancer of the tissue under the skin in which certain cells start to grow out of control. Imatinib inhibits the growth of these cells.
In the rest of this leaflet, the abbreviations will be used when referring to these diseases.
If you have any questions about how imatinib works or why this medicine has been prescribed for you, ask your doctor.
