Selvom samtidig administration af methylprednisolon med en enkelt 40 mg dosis aprepitant ikke er undersøgt, forårsager en enkelt 40 mg dosis aprepitant en svag hæmning af CYP3A4, og det forventes ikke at ændre methylprednisolons plasmakoncentration i klinisk signifikant grad.
Although the concomitant administration of methylprednisolone with the single 40 mg dose of aprepitant has not been studied, a single 40 mg dose of aprepitant produces a weak inhibition of CYP3A4 and it is not expected to alter the plasma concentrations of methylprednisolone to a clinically significant degree.
