Immunosuppressive drugs in organ transplantation to prevent allograft rejection: Mode of action and side effects

Abstract

Organ transplantation is a life-saving therapeutic intervention that contributes to a better quality of life in patients with end-stage organ failure. Drastically improved outcome after organ transplantation occurred with the discovery and use of immunosuppressive drugs to prevent or treat allograft rejection. Development of several immunosuppressive agents offers the option for a multidrug approach with non-overlapping toxicities. Still, the side effects of these agents can be severe, resulting in a shorter life expectancy for transplant patients compared to the general population. Therefore, the development of new immunosuppressive therapies that promote immune tolerance without the side effects observed today is needed. In this review, we will discuss the mechanism of allograft rejection as well as the mode of action and side effects of currently used immunosuppressive agents.
