Mannitol therapy should be discontinued if progression in renal damage or dysfunction, heart failure, or pulmonary congestion occurs. A test dose should be administered in patients with severe renal impairment. Diuresis caused by mannitol administration may exacerbate electrolyte imbalances.
How does mannitol cause renal failure?
Volume depletion and hypernatremia — Mannitol is freely filtered by the glomerulus and does not undergo tubular reabsorption. Thus, it acts as an osmotic diuretic, increasing urinary losses of both sodium and electrolyte-free water.
Why mannitol is contraindicated in acute renal failure?
Mannitol is not metabolized in the body and is not toxic. Be- cause it is not reabsorbed by the renal tubules, it is a highly effective osmotic diuretic.
