Definition:A synthetic glucocorticoid drug that is particularly effective as an immunosuppressant, and affects virtually all of the immune system. Prednisone is a prodrug that is converted by the liver into prednisolone (a β-hydroxy group instead of the oxo group at position 11), which is the active drug and also a steroid.
