 BASILIXIMAB BRAND NAME:- Simulect   BASILIXIMAB is another anti CD - 25 antibody with higher affinity for the IL-2 receptor, but shorter plasma t½ (1 week) . is a monoclonal antibody used to prevent rejection in kidney transplants. It is a chimeric mouse-human monoclonal antibody to the α chain (CD25) of the IL-2 receptor of T cells. It is used in combination with other medicines used to prevent organ rejection. PHARMACODYNAMIC:- Basiliximab functions as an IL-2 receptor antagonist. Specifically it inhibits IL-2-mediated activation of lymphocytes, a critical pathway in the cellular immune response involved in allograft rejection.  MECHANISM OF ACTION:-  Basiliximab competes with IL-2 to bind to the alpha chain subunit of the IL2 receptor on the surface of the activated T lymphocytes and thus prevents the receptor from signaling. This prevents T cells from replicating and also from activating B cells, which are responsible for the production of antibodies, which woul...
