Imuran

Azathioprine, the active ingredient in Imuran, is an immunosuppressant (antimetabolite) presented as a tablet for oral use. It is employed to prevent organ transplant rejection and to manage autoimmune disorders such as rheumatoid arthritis and inflammatory bowel disease, including Crohn's disease and ulcerative colitis, in adult patients.

GNH USA supplies Imuran as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides reliable logistics for global distribution.

Azathioprine is employed in the management of immune‑mediated conditions where suppression of lymphocyte activity is required.

- Organ transplantation prophylaxis: helps prevent rejection of transplanted organs by suppressing the immune response. - Rheumatoid arthritis: reduces joint inflammation and disease progression in adult patients. - Crohn's disease: controls intestinal inflammation and maintains remission in moderate to severe cases. - Ulcerative colitis: diminishes colonic inflammation and supports sustained remission in affected individuals.

Azathioprine may cause a range of adverse reactions, varying from mild to potentially life‑threatening.

Common Side Effects: - Nausea - Vomiting - Loss of appetite - Mild leukopenia - Rash - Fever

Serious or Rare Side Effects: - Severe bone marrow suppression (agranulocytosis, anemia) - Hepatotoxicity - Pancreatitis - Increased susceptibility to infections - Malignancies such as lymphoma - Hypersensitivity reactions including Stevens‑Johnson syndrome

When using Imuran, careful monitoring and specific precautions are recommended to minimize risks.

- Monitor blood counts: regular CBC testing to detect leukopenia or anemia. - Assess liver function: periodic liver enzyme tests are recommended. - Screen for infections: evaluate for active infections before initiating therapy. - Avoid use in pregnancy: drug is classified Category D and may cause fetal harm. - Store at ambient temperature: keep below 25°C in original packaging, protect from moisture.

Azathioprine interacts with several medicines; awareness of major and moderate interactions helps prevent adverse outcomes.

Major Interactions (Avoid): - Allopurinol: may increase azathioprine toxicity, leading to severe bone marrow suppression. - Live vaccines: concurrent use can result in uncontrolled infection. - Warfarin: azathioprine may enhance anticoagulant effect, increasing bleeding risk.

Moderate Interactions (Monitor Closely): - Rituximab: combined immunosuppression may raise infection risk. - Sulfasalazine: may increase risk of myelosuppression. - ACE inhibitors: monitor renal function and blood pressure.
