Neopax is used to treat several cancers in both adults and children. In particular, they apply: in the treatment of chronic myeloid leukemia (CML), if bone marrow transplantation is not expected, or after unsuccessful treatment with interferons, other forms of this type of cancer; with chemotherapy for newly diagnosed acute lymphoblastic leukemia; as monotherapy for acute lymphoblastic leukemia; for the treatment of certain types of myelodysplastic / myeloproliferative diseases; treating hypereosinophilic syndrome and / or chronic eosinophilic leukemia; treatment of metastatic malignant gastrointestinal stromal tumors; dermatofibrosarcoma treatment.
Main active ingredient: imatinib.
Excipients included in the preparation: lactose, starch, cellulose, crospovidone, silicon dioxide, magnesium stearate, etc.
Available in tablet form, 400 mg of imatinib.
Neopax belongs to the drug group of antineoplastic agents, protein kinase inhibitors, and is used in the treatment of various oncological diseases.
The main active ingredient is imatinib, an antineopolastic agent with the ability to inhibit protein kinase. A subclass of enzymes, protein kinases, has the ability to modify proteins (the position of proteins inside the cell, their interaction with other proteins).
Due to the ability of imatinib to suppress (inhibit) enzymes involved in the metabolism of cell lines, including cells affected by leukemia, myeloid leukemia, acute lymphoid leukemia.
Has antitumor activity against malignant neoplasms, when used as a monotherapeutic agent. It also has the ability to inhibit (inhibit) receptors that promote cell growth, to activate kit mutations.
It is highly effective due to the overall response rate of the hematological and cytogenetic systems of the body, especially in patients suffering from acute lymphoblastic leukemia, as well as in patients diagnosed with malignant gastrointestinal stromal tumors.

If the doctor has prescribed a daily dosage of 400 or 600 mg, the drug is taken once a day.
If a dosage of 800 mg is prescribed, the intake of this daily dose is divided into 2 doses per day.
The duration of the course of treatment depends on the reaction of the body to the treatment; it can last from 3 to 30 months or more.
Pediatric dosage is calculated based on the patient’s body area, from 340 to 570 mg per 1 square meter of the patient’s body surface.
Overdose cases are extremely rare.
An overdose of 1200 mg per day for more than 10 days can cause:
- nausea, vomiting, diarrhea, rash;
- thrombocytopenia, milagia, pancytopenia;
- headaches, decreased appetite, facial swelling.
These symptoms are reversible. In this case, symptomatic therapy is recommended.
Possible side effects:
- nausea, vomiting, muscle cramps, swelling of the limbs;
- increased transaminase levels, hyperbilirubinemia;
- herpes, nasopharyngitis, infections and inflammation of the upper respiratory tract, urinary tract, gastroenteritis, sepsis, mycoses;
- tumor lysis syndrome, tumor hemorrhage / necrosis;
- neutropenia, thrombocytopenia, anemia, pancytopenia, bone marrow suppression, eosinophilia, lymphadenopathy;
- anorexia, hypokalemia, dehydration, gout, hyperuricemia, hypercalcemia, hyperglycemia, hyponatremia, hyperkalemia, hypomagnesemia;
