Precautions recommended for Glivec in patients with severe renal dysfunction, regular hemodialysis treatments, severe liver disease, cardiovascular disease or risk factors for heart failure.

Dosage and Administration

Glivec is taken orally with meals, abundantly (at least 1 cup) with water.

If necessary, tablets or capsules, the content can be dissolved in water or apple juice to form a slurry.The suspension was prepared immediately before taking a proportion of 50 ml liquid formulation or 100 mg per 100 ml - 400 mg.

dose and treatment period determined by a physician based on clinical indications.

Purpose of 400 and 600 mg taken once a day 1, 800 mg - 2 divided doses (morning and evening) 400 mg.

Recommended dosage:

  • Chronic myeloid leukemia: chronic phase - 400 mg per day, in accelerated phase and blast crisis - 600 mg per day.With good tolerability and absence of neutropenia, thrombocytopenia or other unwanted effects, showing increasing doses up to 800 mg in the progression of any stage CML absence after 3 months of therapy satisfactory hematological or 12 months - cytogenetic response and, in case of loss of the previously reached hematological and / orcytogenetic indices.For children (2 years of age), the dose determined on the basis of body surface area - 340 mg per 1 m2 but not more than 600 mg per day.The calculated dose the child can be taken once or in equal parts, 2 times a day;
  • PH-positive acute lymphoblastic leukemia: 600 mg per day;
  • Myeloproliferative and myelodysplastic disease: 400 mg per day;
  • metastatic and / or unresectable malignant gastrointestinal stromal tumors gastrointestinal tract (GIT): 400 mg per day, in low clinical effect and the absence of side reactions the dose may be increased to 600 or 800 mg.Patients with evidence of progression of disease receiving Glivec should be abolished;
  • Adjuvant therapy of gastrointestinal stromal tumor: 400 mg per day for 36 months or more;
  • dermatofibrosarcoma protuberans (inoperable, recurrent and / or metastatic): 800 mg per day;Systemic mastocytosis
  • absence D816V c-Kit mutations: 400 mg.Patients with unknown mutation status and with little effect of the previous treatment - 400 mg per day;
  • Systemic mastocytosis due to abnormal FIP1L1-PDGFR alpha fusion tyrosine kinase genes in the background Fip like1 and PDGFR: initial dose - 100 mg per day, with a possible increase to 400 mg per day;
  • hypereosinophilic syndrome and / or chronic eosinophilic leukemia (HES / CEL): adult patients - 400 mg per day.When HES / HAL from the anomalous FIP1L1-PDGFR-alpha kinase - initial dose should be 100 mg per day, and to increase the efficiency in the absence of serious adverse effects, the dose can be increased to 400 mg per day.

Receiving Imatinib lasts until the termination of the clinical effect.

patients with mild, moderate or severe form of the functional liver disorder drug administered in a daily dose of no more than 400 mg.With the development of toxic side effects, the dose should be reduced.Particular caution should be exercised when administering the drug to patients with severe hepatic insufficiency.

If the kidney function, including severe or systematic hemodialysis initial dose is 400 mg 1 time per day.

Patients with poorly tolerated imatinib starting dose may be reduced at low efficiency - increase.

correction dosing regimen for elderly patients is not required.

In case of serious non-hematologic adverse events in patients receiving Glivec treatment should be repealed before the elimination of the symptoms of disorders of the patient.

drug overturned by increasing the concentration of bilirubin in 3 times, liver transaminases in blood serum - 5 times higher than in congenital adrenal hyperplasia (CAH).After the restoration of the bilirubin concentration (less than 1.5 × ULN) and the liver transaminases (less than 2.5 × ULN) the drug is resumed.Treatment continues by lowering the initial daily dose: 800 mg to 600 mg, from 600 mg to 400 mg, from 400 mg to 300 mg;in children - from 340 to 260 mg per 1 m2.

Temporary cancellation of therapy or dose reduction is required for the appearance of neutropenia and thrombocytopenia.

for systemic mastocytosis and HES / CEL (caused by abnormal FIP1L1-PDGFR alpha-tyrosine kinase), chronic phase CML (adults and children), malignant stromal gastrointestinal tumors, myelodysplastic or myeloproliferative pathologies, systemic mastocytosis and HES / CEL after reaching an absolute neutrophil count1500 / l and platelet count more than 75,000 / microliter shown resumption of treatment in the initial dose.In case of repeated reduction in the number of neutrophils and platelets after another cancellation treatment should be initiated at a dose: adults - 300 mg, children - 260 mg per 1 m2.

patients with an absolute neutrophil count less than 500 / l and / or platelet count less than 10,000 / microliter patients with PH-positive acute lymphoblastic leukemia and CML in accelerated phase and blast crisis (children and adults) after one or more months of therapy, make surethat is not associated with cytopenia leukemia.If cytopenia is not due to leukemia dose of Glivec is reduced to 400 mg in adults and up to 260 mg per 1 m2 in children, while maintaining cytopenia after 2 weeks of therapy dose should be again reduced to 300 mg and 200 mg per 1 m2, respectively.If no effect after 4 weeks of drug therapy to restore the overturned absolute neutrophil count to 1000 / mm and more platelets 20,000 / ul.Adults begin receiving a dose of 300 mg, children - 260 mg per 1 m2.

When dermatofibrosarcoma protuberans in unresectable, recurrent and / or metastatic after discontinuation resume treatment at a dose of 600 mg, with repeated decrease in the number of neutrophils and / or platelet count - 400 mg after recovery state.
