About

Imatinib is a potent tyrosine kinase inhibitor primarily used in the treatment of various cancers, most notably Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML) and gastrointestinal stromal tumors (GIST). It works by selectively inhibiting the Bcr-Abl tyrosine kinase, which is a constitutively active enzyme found in CML cells, and also inhibits other receptor tyrosine kinases such as KIT and PDGF-R, which are implicated in GIST and other malignancies.

By targeting these specific molecular pathways, imatinib effectively blocks the proliferation and induces apoptosis of cancer cells, leading to significant clinical responses and improved survival rates in patients with these conditions. Its introduction revolutionized the treatment landscape for CML, transforming it from a rapidly fatal disease into a manageable chronic condition for many patients. Regular monitoring of blood counts and liver function is essential during treatment.

Uses

Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML).
Gastrointestinal stromal tumors (GIST) that are unresectable or metastatic.
Myelodysplastic/myeloproliferative diseases (MDS/MPD).
Hypereosinophilic syndrome (HES) and/or chronic eosinophilic leukemia (CEL).

Directions For Use

Take orally once daily with a meal and a large glass of water, as prescribed by your oncologist.

Safety Measures

Alcohol - Avoid excessive alcohol consumption as it may increase the risk of liver toxicity, a known side effect of imatinib.
Pregnancy - Imatinib can cause fetal harm. It is not recommended during pregnancy, and effective contraception should be used by women of childbearing potential.
Breastfeeding - Imatinib is excreted in human milk. Due to the potential for serious adverse reactions in breastfed infants, breastfeeding is contraindicated.
Liver - Use with caution in patients with hepatic impairment. Liver function tests should be monitored regularly, and dose adjustments may be necessary.
Kidney - Use with caution in patients with renal impairment. Dose adjustments may be required, especially in severe cases.
Lung - Rare but serious pulmonary adverse events, including interstitial lung disease and pulmonary hypertension, have been reported. Monitor for new or worsening respiratory symptoms.
