This higher strength tablet suits patients on standard maintenance doses, taken once daily with food.

Glivec 400mg Tablet Ingredients and Usage

Glivec 400mg Tablet contains imatinib mesylate, a small molecule tyrosine kinase inhibitor. Doctors prescribe it for Philadelphia chromosome positive chronic myeloid leukemia, where the standard maintenance dose for newly diagnosed chronic phase disease is 400mg once daily.

Glivec 400mg Tablet also treats gastrointestinal stromal tumors, Philadelphia chromosome positive acute lymphoblastic leukemia, myelodysplastic and myeloproliferative diseases, systemic mastocytosis, hypereosinophilic syndrome, and dermatofibrosarcoma protuberans. Some indications require higher doses of 600mg or 800mg daily, guided by a specialist experienced in these disorders.

How Does Glivec 400mg Tablet Work?

Imatinib inhibits the Bcr-Abl tyrosine kinase, an abnormal enzyme produced by the Philadelphia chromosome that drives uncontrolled white blood cell growth in chronic myeloid leukemia. It also inhibits related kinases, including KIT and platelet derived growth factor receptors.

By blocking these kinases, Glivec 400mg Tablet stops the proliferation signal that keeps cancer cells dividing and triggers apoptosis, or programmed cell death, in cells that depend on this abnormal signaling. This targeted mechanism underlies its activity across leukemia, GIST, and other kinase driven conditions.
