Update on transplant pharmacology: sirolimus.

Rapamune (Sirolimus), the latest immunosuppressant agent for solid organ transplants, is prescribed for induction therapy, refractory rejection, steroid withdrawal, and combination therapy. As the use of this agent increases among various transplant populations, it is essential for critical care nurses to be cognizant of the indications, pharmacodynamics, current research findings, side effects, and implications. This knowledge will ultimately improve patient education and outcomes in this ever-growing field of nursing.
