Prednisolone is a derivative of cortisol and a metabolite of prednisone; it exhibits immunosuppressive and anti-inflammatory activities. Prednisolone activates glucocorticoid receptors and is clinically used to treat inflammatory and autoimmune disorders. In mononuclear cells from subjects with multiple sclerosis, prednisolone decreases expression of T-bet, IFNγ, and phosphorylated STAT1, decreasing lymphocyte apoptosis. Additionally, prednisolone delays the progression of Duchenne muscular dystrophy (DMD), altering muscle fiber types in vivo. This form of prednisolone is water soluble.
