Introduction to Gleevec (Imatinib) 400mg 

Gleevec (Imatinib) 400mg is a targeted prescription medicine used in the treatment of certain cancers, particularly blood cancers and gastrointestinal tumors. It is widely known for its effectiveness in treating chronic myeloid leukemia (CML).

In some markets, Imanix 400mg is available as a local brand containing the same active ingredient Imatinib, offering similar therapeutic effects when prescribed by a qualified healthcare professional.
