imatinibin

Imatinib, marketed as Gleevec or Glivec, is a medication used to treat certain types of cancer. It belongs to a class of drugs called tyrosine kinase inhibitors. Imatinib works by blocking the action of specific proteins that are involved in the growth and spread of cancer cells.

This drug is primarily used to treat Philadelphia chromosome-positive chronic myeloid leukemia (CML) and certain types of gastrointestinal stromal tumors (GIST). It is also approved for treating other rare conditions like myelodysplastic/myeloproliferative diseases and hypereosinophilic syndrome. Imatinib has significantly improved outcomes for patients with these diseases.

The effectiveness of imatinib lies in its targeted approach. Instead of broadly affecting all rapidly dividing cells, like traditional chemotherapy, it focuses on cancer cells that have specific genetic mutations driving their growth. This targeted action often leads to fewer severe side effects compared to conventional treatments.

Imatinib is taken orally, usually once or twice a day, depending on the condition being treated. Like all medications, it can have side effects, which may include nausea, muscle cramps, fatigue, and swelling. Regular monitoring by a healthcare professional is essential to manage treatment and assess its effectiveness and any potential side effects. The development of imatinib represented a major advance in the field of targeted cancer therapy.
