Indications & Clinical Uses

  • Imatinib acts on malignant cells driven by BCR‑ABL, c‑KIT or PDGFR signaling pathways.
  • Chronic Myeloid Leukemia: provides targeted inhibition of leukemic cell proliferation.
  • Gastrointestinal Stromal Tumor: controls tumor growth by blocking KIT‑driven signaling.
  • Philadelphia‑positive Acute Lymphoblastic Leukemia: offers targeted therapy to improve remission rates.

How It Works

  • Imatinib binds to the ATP‑binding site of BCR‑ABL, c‑KIT and PDGFR tyrosine kinases, stabilizing them in an inactive conformation. This blocks downstream phosphorylation cascades that drive cell proliferation and survival, thereby suppressing the growth of malignant clones that depend on these oncogenic kinases.

Side Effects

Imatinib may cause a range of adverse reactions that vary in frequency and severity.

Common Side Effects

  • Nausea and vomiting
  • Fluid retention or peripheral edema
  • Muscle cramps or weakness
  • Fatigue
  • Diarrhea
  • Rash or mild skin irritation

Serious or Rare Side Effects

  • Hepatotoxicity (elevated liver enzymes or hepatitis)
  • Severe neutropenia or thrombocytopenia
  • Cardiac failure or reduced left‑ventricular function
  • Pulmonary arterial hypertension
  • Severe skin reactions such as Stevens‑Johnson syndrome
  • Tumor lysis syndrome in high‑burden disease

Precautions & Warnings

  • Before initiating therapy, clinicians should assess baseline organ function and monitor patients regularly.
  • Monitor blood counts: perform complete blood count at baseline and periodically.
  • Assess liver function: check hepatic enzymes before treatment and during therapy.
  • Evaluate cardiac status: perform ECG or echocardiogram in patients with cardiac risk factors.
  • Avoid in severe hypersensitivity: discontinue if anaphylactic reaction occurs.
  • Use caution in renal impairment: adjust monitoring in patients with reduced clearance.
  • Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Avoid Interactions

Imatinib interacts with several medicines that affect its metabolism or pharmacodynamic profile.

Major Interactions (Avoid)

  • Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): may increase imatinib exposure.
  • Strong CYP3A4 inducers (e.g., rifampin, carbamazepine): may reduce therapeutic levels.
  • Concomitant use with potent P‑glycoprotein inhibitors (e.g., verapamil): may raise plasma concentrations.

Moderate Interactions (Monitor Closely)

  • CYP3A4 substrates with narrow therapeutic index (e.g., midazolam, tacrolimus): monitor levels.
  • Anticoagulants such as warfarin: watch INR for potential changes.
  • Diuretics (e.g., furosemide): monitor electrolytes and renal function.

Frequently Asked Questions

Imatinib Teva is indicated for the treatment of chronic myeloid leukemia, gastrointestinal stromal tumor, and Philadelphia‑positive acute lymphoblastic leukemia. In each case, the drug targets specific tyrosine kinases that drive the growth of malignant cells, providing a targeted therapeutic approach.

Imatinib binds to the ATP‑binding pocket of BCR‑ABL, c‑KIT and PDGFR tyrosine kinases, locking them in an inactive state. This blocks downstream signaling pathways that promote cell proliferation and survival, thereby inhibiting the expansion of cancerous cells that rely on these kinases.

The dosage of Imatinib Teva is individualized by the prescribing clinician based on the specific indication, disease stage, patient weight, renal and hepatic function, and other clinical factors. Patients should follow the exact regimen provided by their healthcare professional.

Imatinib is classified as contraindicated in pregnancy because it may cause fetal harm. Women of childbearing potential should use effective contraception. Breastfeeding is not recommended while receiving imatinib, as the drug can be excreted in milk and affect the infant.

To place an order, submit an enquiry on the Imatinib Teva product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Imatinib was the first BCR‑ABL tyrosine kinase inhibitor approved for chronic myeloid leukemia and remains a standard first‑line option. Newer agents such as dasatinib or nilotinib may offer different potency or side‑effect profiles, but imatinib’s long‑term safety data and cost‑effectiveness make it a widely used choice.

Imatinib Teva should be stored at room temperature, below 25 °C, in its original packaging. Protect the tablets from moisture, excessive heat and direct sunlight to maintain product stability throughout its shelf life.

Imatinib Teva is taken orally, usually as a whole tablet with a glass of water. It can be taken with or without food, but patients should follow any specific instructions from their prescriber regarding timing relative to meals.

Serious risks include hepatotoxicity, severe neutropenia or thrombocytopenia, cardiac failure, pulmonary arterial hypertension, and rare severe skin reactions such as Stevens‑Johnson syndrome. Patients should be monitored regularly for signs of these events, and therapy should be discontinued if they occur.

Imatinib Teva is contraindicated in patients with known hypersensitivity to imatinib or any of its excipients. It should also be avoided in pregnant women and used with caution in individuals with severe hepatic impairment, significant cardiac disease, or uncontrolled infections.
