Active Ingredient: Imatinib
Imatinib is indicated for the treatment of:
For this indication, competent medicine agencies globally authorize below treatments:
Oral, between 170 milligrams imatinib per square meter of body surface and 285 milligrams imatinib per square meter of body surface, 2 times daily.
Dosing for children should be on the basis of body surface area (mg/m²). The dose of 340 mg/m² daily is recommended for children with chronic phase CML and advanced phase CML (not to exceed the total dose of 800 mg). Treatment can be given as a once daily dose or alternatively the daily dose may be split into two administrations – one in the morning and one in the evening. The dose recommendation is currently based on a small number of paediatric patients. There is no experience with the treatment of children below 2 years of age.
Dose increases from 340 mg/m² daily to 570 mg/m² daily (not to exceed the total dose of 800 mg) may be considered in children in the absence of severe adverse drug reaction and severe non-leukaemia-related neutropenia or thrombocytopenia in the following circumstances: disease progression (at any time); failure to achieve a satisfactory haematological response after at least 3 months of treatment; failure to achieve a cytogenetic response after 12 months of treatment; or loss of a previously achieved haematological and/or cytogenetic response. Patients should be monitored closely following dose escalation given the potential for an increased incidence of adverse reactions at higher dosages.
The prescribed dose should be administered orally with a meal and a large glass of water to minimise the risk of gastrointestinal irritations.
