Anti-rejection pills refer to immuno-suppressive drugs, correct?  They are taken after a surgery so that the body's immune system is more likely to accept an organ.  Here are some examples:

Immunosuppressive drugs used to treat transplant rejection

    * Calcineurin inhibitors

          o Cyclosporin

          o Tacrolimus

    * mTOR inhibitors

          o Sirolimus

          o Everolimus

    * Anti-proliferatives

          o Azathioprine

          o Mycophenolic acid

    * Corticosteroids

          o Prednisolone

          o Hydrocortisone

    * Antibodies

          o Monoclonal anti-IL-2Rα receptor antibodies

                + Basiliximab

                + Daclizumab

          o Polyclonal anti-T-cell antibodies

                + Anti-thymocyte globulin (ATG)

                + Anti-lymphocyte globulin (ALG)

Answer 2

They are typically drugs used to suppress the immune system so that it does not attack and reject a foreign organ. Usually, they are specifically trying to suppress the leukocytes (white blood cells) from attacking the new organ.
