Mode of Action

Azathioprine is an imidazolyl derivative of mercaptopurine, which inhibits DNA, RNA and protein synthesis and antagonises purine synthesis. It also inhibits mitosis and interferes with cellular metabolism of susceptible organisms. Azathioprine inj should be converted to oral therapy as soon as the drug can be tolerated.

Interaction

Increased risk of haematotoxicity with aminosalicylates, drugs that affect myelopoesis e.g. co-trimoxazole or trimethoprim. Increased risk of infections with intra-uterine devices and live vaccines. Increased risk of leucopenia with ACE inhibitors. Concurrent use may reduce the anticoagulant effect of vitamin K antagonists e.g. warfarin. Increased risk of myelosuppressive effects when used with drugs that inhibit TPMT (thiopurine methyltransferase) or xanthine oxidase e.g. olsalazine, allopurinol. Potentially Fatal: Increased risk of serious haematotoxicity or hepatotoxicity with leflunomide. Increased risk of bone marrow suppression with mycophenolate mofetil. Increased risk of infections and malignancies with efalizumab.
