After such high-dose initial immunosuppression, the patient is put on a lifelong course of relatively high doses of antirejection drugs to prevent long-term ("chronic") rejection. For patients with end-stage organ failure, solid organ transplantation is life-saving and cost-effective; however, transplant recipients require use of immunosuppressive agents for the rest of their lives to maintain a functioning graft. The antimetabolite immunosuppressive drugs commonly used after transplant include azathioprine (AZA) and mycophenolic acid (MPA). Background.
