WebMannitol is the osmotic diuretic most widely used in the United States. A 20 % solution of mannitol, 0.25 g to 1 g/kg infused intravenously over 15 minutes, exerts its beneficial effects as a plasma expander and as an osmotic diuretic. Hypertonic saline causes similar vascular changes to mannitol. http://chikd.org/journal/view.php?id=10.3339/jkspn.2016.20.1.11

What is the osmotic gradient of Corticomedullary? The countercurrent multiplication along Henle loops, driven by active NaCl retrieval across the water-impermeable ascending limb, causes this rise in tissue osmolarity, or cortico-medullary osmotic gradient.
