Imatinib 400 mg

Imatinib 400 mg is a widely prescribed anticancer medication used in the treatment of specific types of cancers, particularly Chronic Myeloid Leukemia (CML) and Gastrointestinal Stromal Tumors (GIST). It belongs to a class of drugs known as tyrosine kinase inhibitors (TKIs), which are designed to target and block abnormal proteins responsible for the growth of cancer cells.

Imatinib works by inhibiting the activity of the BCR-ABL tyrosine kinase enzyme, a protein that promotes uncontrolled cell division in certain cancers. By blocking this enzyme, Imatinib 400 mg tablets help slow down or stop the progression of cancer, making it an essential part of targeted cancer therapy.

🔬 Mechanism of Action

Imatinib specifically inhibits abnormal proteins known as tyrosine kinases, particularly the BCR-ABL enzyme produced by the Philadelphia chromosome in certain cancers. This enzyme signals cancer cells to grow and divide uncontrollably.

By blocking this activity, Imatinib 400 mg tablets help stop the proliferation of cancer cells, induce apoptosis (programmed cell death), and slow disease progression. It may also inhibit other kinases such as c-KIT and PDGFR, which are involved in tumor growth in GIST and other malignancies.

🩺 Uses of Imatinib 400 mg

Imatinib 400 mg is prescribed for the treatment of:

• Chronic Myeloid Leukemia (CML)
• Acute Lymphoblastic Leukemia (Ph+ ALL)
• Gastrointestinal Stromal Tumors (GIST)
• Myelodysplastic/Myeloproliferative diseases (MDS/MPD)
• Dermatofibrosarcoma Protuberans (DFSP)

This medication is a key component in modern oncology treatment plans, improving survival rates and disease management.
