Methylprednisolone belongs to the group of synthetic glucocorticoids. Glucocorticoids penetrate cell membranes and form complexes with specific cytoplasmic receptors. Then these complexes penetrate the cell nucleus, bind to DNA (chromatin), stimulate mRNA transcription and subsequent protein synthesis of various enzymes, which explains the effect of systemic use of glucocorticoids. Glucocorticoids not only have a significant effect on the inflammatory process and immune response, but also affect carbohydrate, protein and fat metabolism, the cardiovascular system, skeletal muscles and the central nervous system.
