Immunosuppressive therapy aims to protect transplanted organs from host responses. The success achieved during the last two decades in patient and graft survival is mainly related to the development and clinical use of efficacious immunosuppressive drugs. Nevertheless, the challenge of achieving a balance of adequate graft protection while minimizing the adverse consequences of excessive immunosuppression in the long-term continues. Current maintenance immunosuppression for renal transplant recipients generally consists of a calcineurin inhibitor plus an adjunctive antiproliferative agent, and steroids. The addition of induction therapy with a variety of monoclonal or polyclonal antibodies provides a more potent immunosuppression and its use is more relevant in patients with a high immunological risk. More recently, mammalian target of rapamycin inhibitors have been incorporated in different schemes proven its efficacy in a number of protocols. The incidence of acute rejection is now in its lower historical percentage and excellent results are reported from many transplant centers all over the world due mainly to a judicious combination of these drugs evaluated through many clinical studies. However, long-term use of immunosuppressive drugs convey inherent risks which translate in an increase of cancers and infections, among others. Ongoing investigations and clinical protocols involving new immunosuppressive drugs and biological agents are yielding important information on how to obtain tolerance or the nearest to this goal. Furthermore, there should be a continuous improvement in patient and graft survival, as the use of different immunosuppressive agents for induction and maintenance are individualized (adapted to each patient).
