Imarech contains Imatinib mesylate 400mg as an active ingredient and this tablet belongs to a class of medication known as tyrosine kinase inhibitors. Imatinib 400mg tablet is used for the treatment of a type of blood cancer known as CML (chronic myeloid leukemia) ALL (Acute lymphocytic leukemia) and gastrointestinal stromal tumor.

Imatinib 400mg tablet is an antineoplastic agent and a protein-tyrosine kinase inhibitor that inhibits the BCR-ABL tyrosine kinase, and it works as a specific inhibitor of several tyrosine kinase enzymes. Chronic myelogenous leukemia is associated with the Philadelphia chromosome promoting the generation of BCR-ABL (mutation, which results from the combination of two genes, known as BCR and ABL). BCR-ABL generates a fusion protein that acts as a constitutively active tyrosine kinase and imatinib tablet works to inhibit this constitutive enzymatic activity.
