Imasup

Azathioprine, the active ingredient in Imasup, is an immunosuppressant presented as an oral formulation for oral use. It is employed to prevent organ rejection after transplantation and to manage autoimmune disorders such as rheumatoid arthritis and inflammatory bowel disease.

GNH USA supplies Imasup as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, pharmacies and clinics worldwide.

Azathioprine is an immunosuppressive agent used in several chronic immune‑mediated conditions. - Organ transplantation: helps prevent graft rejection by suppressing the immune response. - Rheumatoid arthritis: reduces joint inflammation and slows disease progression. - Inflammatory bowel disease: controls chronic intestinal inflammation in Crohn's disease and ulcerative colitis.

Azathioprine may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Nausea or vomiting: gastrointestinal discomfort often occurring early in therapy. - Leukopenia: reduced white blood cell count, increasing infection risk. - Hepatotoxicity: elevated liver enzymes indicating liver stress. - Rash or mild skin irritation.

Serious or Rare Side Effects: - Severe bone marrow suppression: pancytopenia requiring immediate medical attention. - Opportunistic infections: due to profound immunosuppression. - Increased risk of certain malignancies, such as lymphoma. - Pancreatitis: acute abdominal pain with elevated enzymes.

Before initiating therapy, clinicians should assess baseline laboratory values and monitor regularly. - Baseline labs: obtain complete blood count and liver function tests. - Infection risk: screen for latent infections (e.g., TB, hepatitis) before treatment. - Pregnancy: avoid use unless benefits outweigh risks; discuss with a specialist. - Drug interactions: review concomitant medications for potential additive immunosuppression. - Renal/hepatic impairment: adjust dose or monitor closely in patients with organ dysfunction. - Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture and direct sunlight.

Azathioprine can interact with several drug classes, altering efficacy or safety.

Major Interactions (Avoid): - Allopurinol or febuxostat: may cause severe bone marrow suppression. - Warfarin: increased anticoagulant effect, requiring INR monitoring. - Live vaccines: heightened risk of infection; avoid concurrent use.

Moderate Interactions (Monitor Closely): - Antacids containing magnesium or aluminum: may reduce absorption. - Ribavirin: additive hematologic toxicity. - Mycophenolate mofetil: combined immunosuppression may increase infection risk.
