Introduction
An osmotic diuretic.a b
Uses for Mannitol (Diuretic)
Oliguric Acute Renal Failure
Used to promote diuresis for the prevention and/or treatment of the oliguric phase of acute renal failure, which may occur after massive hemorrhage, trauma, shock, burns, transfusion reactions caused by mismatched blood, or major surgery before there is evidence of tubular necrosis or multiple vascular thrombosis.a b
Has been used to reduce nephrotoxicity caused by amphotericin B.a
Has no effect and may be harmful if used after tubular necrosis and irreversible renal failure become established.a b
Reduction of Intracranial Pressure
Used prior to and during neurosurgery to reduce greatly increased intracranial pressure and for the treatment of cerebral edema.a b Also may be used for early treatment of cerebral edema in patients with diabetic ketoacidosis or in those in hypoglycemic coma who fail to respond to increases of blood glucose concentrations.a
Reduction of Intraocular Pressure
Used to reduce elevated intraocular pressure (IOP) when the pressure cannot be lowered by other means.a b Especially useful for treating acute episodes of angle-closure, absolute, or secondary glaucoma and for lowering IOP prior to intraocular surgery.a
Urinary Excretion of Toxins
Used alone or with other diuretics (e.g., furosemide, ethacrynic acid) to promote the urinary excretion of toxins (e.g., aspirin or other salicylates, some barbiturates, bromides, imipramine) as an adjunct to usual treatment regimens in patients with severe intoxications.a b
Transurethral Prostatic Resection and Transurethral Prostatectomy
Used as an irrigating solution in transurethral prostatic resectiond to minimize the hemolytic effects of water, the entrance of hemolyzed blood into the circulation, and the resulting hemoglobinemia which is considered a major factor in producing serious renal complications.a
Also has been administered IV before, during, and after transurethral prostatectomy† to maintain urine output, promote rapid excretion of absorbed irrigants, and reduce the need for postoperative irrigation.a
Hyperuricemia
Has been used to promote excretion of uric acid and prevent hyperuricemia and/or uric acid nephropathy† in patients who develop uricemia following chemotherapy or radiation therapy for leukemia or lymphoma.a
Ciguatera Toxicity
Has been used as initial therapy, in combination with other supportive therapy, to reverse neurologic and neurosensory manifestations as well as GI manifestations of ciguatera fish poisoning†.102 a
Edema and Ascites
Has been used alone or in conjunction with other diuretics to promote diuresis for the supportive treatment of edema and ascites† of nephrotic, cirrhotic, or cardiac origin.a
Mannitol (Diuretic) Dosage and Administration
General
Dosage, concentration of solution, and rate of administration vary with the condition being treated and the patient’s fluid requirements, urinary output, and response to the drug.a
Do not administer drug until adequacy of patient's renal function and urine flow have been established.a
Replace fluids, plasma, blood, and electrolytes prior to initiating therapy in patients with shock with oliguria and rising BUN.a
Administration
Administer mannitol injection IV.a b Administer sorbitol-mannitol irrigation solution by transurethral instillation.d
IV Administration
For drug compatibility information, see Compatibility under Stability.
Administer by IV infusion using an administration set with a filter.a b
When used in surgical procedures to prevent oliguric acute renal failure, administration may be initiated before or immediately following surgery and may be continued postoperatively.a
When used preoperatively to reduce IOP, administer 1–1.5 hours prior to surgery in order to achieve maximum reduction of pressure before surgery.a b
Test Dose
Administer a test dose to patients with marked oliguria or suspected inadequate renal function to establish renal response before therapy is initiated.a b
A response is considered adequate if at least 30–50 mL of urine per hour is excreted over the next 2–3 hours.a b
If an adequate response is not attained, a second test dose may be given.a b
If a satisfactory response is not obtained after the second test dose, reevaluate patient, and mannitol should not be used.a b
Rate of Administration
Test dose in adults and children >12 years of age: Infuse over a period of 3–5 minutes to produce urine flow of ≥30–50 mL/hour.a b
Treatment of oliguria in adults: Infuse over 90 minutes to several hours.a
Cerebral or ocular edema in children >12 years of age: Usually, infuse over 30–60 minutes.a
Reduction of intracranial or IOP in adults: Usually, infuse over 30–60 minutes.a
Edema and ascites† in adults and children >12 years of age: Has been infused over 2–6 hours.a
Transurethral Irrigation
Sorbitol-mannitol irrigation solution is for urologic irrigation only; do not use for injection.d
Administer only by transurethral instillation using appropriate and disposable urologic instrumentation.d
Placing the flexible irrigation container >60 cm above the operating table may increase intravascular absorption of irrigation solution.d

Warnings/Precautions
Warnings
Fluid and Electrolyte Imbalance
Risk of serious electrolyte disturbances (e.g., hyponatremia, hypernatremia, hypokalemia, hyperkalemia); may be severe enough to alter acid-base balance or depress respiration.a b Thiazides may be used if hypernatremia or hyperosmolality occurs.a
Accumulation of mannitol caused by inadequate urinary output or rapid administration of large doses may result in overexpansion of extracellular fluid and circulatory overload causing signs and symptoms of water intoxication.a Overhydration may be corrected by hemodialysis or administration of a potent diuretic (e.g., furosemide).a
If urine output declines during administration, review patient’s clinical status and discontinue mannitol if necessary.a
Stop or slow mannitol if central venous pressure rises or there is any other evidence of circulatory overload.a Fluid administration should not exceed 1 L/day in excess of urinary output.a
Sustained diuresis may result in intensification of preexisting hemoconcentration; also may result in hypovolemia which reduces glomerular filtration rate and enhances the reabsorption of sodium and water.a b
Prevent or treat volume and electrolyte depletion by administering dilute mannitol solutions with sodium chloride added or by alternating each liter of mannitol solution with a liter of sodium chloride injection to which 40 mEq of potassium chloride has been added.a If the threat of renal shutdown exists, potassium supplementation should be administered subsequent to, but not concomitantly with, mannitol.a
Cardiovascular Effects
Overexpansion of extracellular fluid (see Fluid and Electrolyte Imbalance under Cautions) may result in pulmonary edema and fulminating CHF, especially in patients with diminished cardiac reserve.a b Carefully evaluate cardiovascular status prior to administration.b
Renal Effects
Possible irreversible vacuolar nephrosis.a b
General Precautions
Pseudoagglutination
Possible pseudoagglutination if electrolyte-free mannitol solutions are given concomitantly with blood.a If blood must be given simultaneously with mannitol, add ≥20 mEq of sodium chloride to each liter of mannitol solution.a
Patient Monitoring
Carefully monitor for fluid and electrolyte imbalances.a b
Monitor urine output; serum sodium and potassium concentrations; central venous pressure; degree of hemoconcentration or hemodilution; and renal, cardiac, and pulmonary function.a b
Use of Fixed-combination Urogenital Irrigation Solution
When sorbitol-mannitol irrigation solution is used, consider the cautions, precautions, and contraindications associated with sorbitol.d
Specific Populations
Pregnancy
Category C.b d
Lactation
Not known whether mannitol is distributed into milk.b Caution advised if mannitol is used.b
Pediatric Use
Safety and efficacy of mannitol injections not established in children <12 years of age.b
Safety and efficacy of sorbitol-mannitol irrigation solution not established.d
Geriatric Use
Insufficient experience in patients ≥65 years of age in clinical trials;b however, response does not appear to differ from that in younger adults.b Select dosage with caution due to greater frequency of decreased hepatic, renal, and/or cardiac function and of concomitant disease and drug therapy observed in the elderly.b
Substantially eliminated by kidneys; assess renal function periodically since geriatric patients more likely to have decreased renal function.b
Renal Impairment
Substantially eliminated by kidneys; increased risk of toxic reactions.b
Administer a test dose to patients with severe renal impairment. (See Test Dose under Dosage and Administration.)

Mannitol (Diuretic) Pharmacokinetics
Absorption
Bioavailability
Has been thought not to be absorbed when administered orally; however, about 17% of an oral dose was excreted unchanged in urine.a
Absorbed into systemic circulation following transurethral instillation as sorbitol-mannitol irrigation solution.d
Onset
Following IV administration, diuresis generally occurs within 1–3 hours, lowering of elevated CSF pressure occurs within 15 minutes, and lowering of elevated intraocular pressure occurs within 30–60 minutes.a
Duration
Lowering of elevated CSF pressure and elevated IOP persists for 3–8 and 4–6 hours, respectively, after infusion is stopped.a
Distribution
Extent
Following IV administration, mannitol remains confined to the extracellular compartment; does not cross the blood-brain barrier unless very high concentrations are present in the plasma or the patient has acidosis; and does not penetrate the eye.a
Elimination
Metabolism
Slightly metabolized to glycogen in the liver.a b
Elimination Route
Freely filtered by the glomeruli, with <10% tubular reabsorption; not secreted by tubular cells.a
Excreted principally in urine as unchanged drug.a
Half-life
100 minutes.a
Special Populations
Decreased clearance in patients with renal disease in which glomerular function is impaired.a
Decreased clearance in patients with conditions that impair small vessel circulation (e.g., CHF, cirrhosis with ascitic accumulation, shock, dehydration).a
Stability
Storage
Parenteral
Powder for Injection
15–30°C; do not freeze.a
Mannitol solutions ≥15% concentrations may crystallize when exposed to low temperatures.a b If crystallization occurs, warm the solution to 70°C and periodically shake vigorously.b Cool solution to room temperature prior to administration.b Do not use the solution if all crystals cannot be completely dissolved.a
Urogenital Irrigation
Solution for Irrigation
25°C.d Do not freeze; avoid excessive heat.d

ActionsActions
Induces diuresis mainly by elevating the osmotic pressure of the glomerular filtrate, which hinders the tubular reabsorption of water and solutes and increases the excretion of sodium.a b
Increased renal blood flow resulting from dilation of vascular segments between the renal artery and glomeruli, lowered renal vascular resistance, and reduced blood viscosity also may contribute to the diuretic effect.a
Increases excretion of potassium, chloride, calcium, phosphorus, lithium, magnesium, urea, and uric acid.a
Increases extracellular fluid volume, plasma volume, and circulation time and dilutes extracellular stores of sodium by causing water to be drawn from cells to extracellular fluid and from erythrocytes to plasma.a Fluid shifts result in reduction of cerebral edema (by reduction in brain mass) and lowering of CSF pressure.a b Reduction of elevated IOP associated with withdrawal of fluids from anterior chamber of the eye.a b
Prevents or reverses acute functional renal failure by reversing the acute reductions in renal blood flow, glomerular filtration rate, urine flow, and sodium excretion that may occur after trauma.a
Protects kidneys from nephrotoxins by preventing toxins from becoming concentrated in the tubular fluid.a
Advice to Patients
