Perdesonide is a glucocorticoid steroid. It is closely related to budesonide and differs by having a difluorinated steroid skeleton. The introduction of the 2 fluorines to the steroid skeleton was shown to increase systemic activity to a greater degree than local activity.[1] Perdesonide resembles clocortolone in that both have two halide atoms; perdesonide has two fluorine atoms and clocortolone has one chlorine atom and one fluorine atom.[2] Perdesonide is racemic at the carbon of the acetal. The R-isomer of the acetal as in (R)-Perdesonide is more active.
