Introduction
Envarsus XR is an immunosuppressive drug used to prevent rejection in organ transplantation, especially kidney transplantation. It is a calcineurin inhibitor that blocks the production of interleukin-2 (IL-2), a necessary component of the immune response, thereby preventing the immune system from attacking a transplanted organ.
Uses_for
Envarsus XR is used for the prevention of kidney, heart, and liver graft rejection. It is also used to treat severe rheumatoid arthritis and a certain skin disease (atopic dermatitis).
