FULL PRESCRIBING INFORMATION: CONTENTS*
Prior to administration of Mannitol Injection, evaluate renal, cardiac, and pulmonary status of the patient and correct fluid and electrolyte imbalances.
The total dosage, concentration, and rate of administration depend on the age, weight, and condition of the patient being treated, including fluid requirement, electrolyte balance, serum osmolality, urinary output, and concomitant therapy.
The following outline of administration and dosage is only a general guide to therapy.
Reduction of Intracranial Pressure and Treatment of Cerebral Edema
Usually a maximum reduction in intracranial pressure can be achieved with a dose of 0.25 g/kg administered as an intravenous infusion over at least 30 minutes, which may be repeated every six to eight hours. During and following infusion of Mannitol Injection, monitor fluid and electrolytes, serum osmolarity, and renal, cardiac, and pulmonary function. Discontinue Mannitol Injection if renal, cardiac, or pulmonary status worsens or CNS toxicity develops [see Warnings and Precautions (5.2, 5.3, 5.4, 5.5)].
Reduction of Intraocular Pressure
The recommended dosage is 1.5 to 2 g/kg as a single dose administered as an intravenous infusion over at least 30 minutes. When used preoperatively, administer Mannitol Injection 60 to 90 minutes before surgery to achieve maximal reduction of intraocular pressure before operation.
Mannitol Injection 25%, USP: 12.5 g/50 mL (0.25 g/mL) of mannitol as a clear and colorless solution in a single-dose vial.
Renal complications, including irreversible renal failure, have been reported in patients receiving mannitol.
The following adverse reactions associated with the use mannitol were identified in clinical studies or postmarketing reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
|Hypersensitivity reactions:||Cardiac arrest, anaphylaxis, hypotension, dyspnea, hypertension, pyrexia, chills, sweating, cough, musculoskeletal stiffness, myalgia, urticaria/rash, pruritus, generalized pain, discomfort, nausea, vomiting, headache [see Warnings and Precautions (5.1)]|
|Renal failure:||Acute kidney injury, osmotic nephrosis, anuria, oliguria, urinary retention [see Warnings and Precautions (5.2)]|
|CNS toxicity:||Coma, seizures, confusion, lethargy, rebound increase in intracranial pressure, headache, dizziness [see Warnings and Precautions (5.3)]|
|Fluid and electrolyte imbalances:||Metabolic acidosis, dehydration (hypovolemia), hypervolemia, hyponatremia, hypernatremia, hyperkalemia, hypokalemia [see Warnings and Precautions (5.4)]|
|Infusion site reactions:||Venous thrombosis, thrombophlebitis extending from the site of injection, compartment syndrome and swelling associated with extravasation [see Warnings and Precautions 5.6)]|
|Cardiac and respiratory disorders:||Tachycardia, angina-like chest pain, congestive heart failure, pulmonary congestion, hypotension, edema, rhinitis|
|Gastrointestinal disorders:||Dryness of mouth, nausea, vomiting|
Concomitant administration of nephrotoxic drugs (e.g., cyclosporine, aminoglycosides) increases the risk of renal failure following administration of mannitol. Avoid use of nephrotoxic drugs with Mannitol Injection, if possible [see Warnings and Precautions (5.2)].
Concomitant administration of other diuretics may potentiate the renal toxicity of mannitol. Avoid concomitant administration of other diuretics with Mannitol Injection, if possible [see Warnings and Precautions (5.2)].
Concomitant administration of systemic neurotoxic drugs (e.g., aminoglycosides) with Mannitol Injection may potentiate the CNS toxicity of mannitol. Avoid use of systemic neurotoxic drugs with Mannitol Injection, if possible [see Warnings and Precautions (5.3)].
The development of electrolyte imbalances (e.g., hyperkalemia, hypokalemia) associated with mannitol administration may result in cardiac adverse reactions in patients receiving drugs that are sensitive to such imbalances (e.g., digoxin, drugs that prolong the QT interval, neuromuscular blocking agents) [see Warnings and Precautions (5.4)]. During and following infusion of Mannitol Injection, monitor serum electrolytes and discontinue Mannitol Injection if cardiac status worsens [see Warnings and Precautions (5.5)].
Mannitol therapy may increase the elimination, and decrease the effectiveness of treatment with, drugs that undergo significant renal elimination. Concomitant administration of mannitol with lithium may initially increase the elimination of lithium but may also increase the risk of lithium toxicity if patients develop hypovolemia or renal impairment. In patients receiving lithium, consider holding lithium doses during treatment with Mannitol Injection. In patients requiring concomitant administration of lithium and Mannitol Injection, frequently monitor serum lithium concentrations and for signs of lithium toxicity.
High concentrations of mannitol can cause false low results for inorganic phosphorus blood concentrations when an assay based on the conversion of phosphate (orthophosphate) to the phosphomolybdate complex is used.
Mannitol may produce false positive results in tests for blood ethylene glycol concentrations in which mannitol is initially oxidized to an aldehyde.
The available case report data with mannitol over decades of use have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Mannitol crosses the placenta and may cause fluid shifts that could potentially result in adverse effects in the fetus (see Data).No adverse developmental effects from mannitol were reported in published animal studies; however, fluid shifts occurred in fetal ewes in response to maternal infusion of mannitol.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
There are no data on the presence of mannitol in either human or animal milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Mannitol Injection and any potential adverse effects on the breastfed child from Mannitol Injection or from the underlying maternal condition.
Mannitol Injection is approved for use in the pediatric population for the reduction of intracranial and intraocular pressure. Studies have not defined the optimal dose of Mannitol Injection in the pediatric population. The safety profile for mannitol use in pediatric patients is similar to adults at dosages described in labeling. However, pediatric patients less than two years of age, particularly preterm and term neonates, may be at higher risk for fluid and electrolyte abnormalities following administration of Mannitol Injection due to decreased glomerular filtration rate and limited ability to concentrate urine [see Warnings and Precautions (5.4)].
Mannitol is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in elderly patients with impaired renal function. Evaluate the renal, cardiac and pulmonary status of the patient and correct fluid and electrolyte imbalances prior to administration of Mannitol Injection [see Warnings and Precautions (5.2, 5.3, 5.4, 5.5)].
Patients with pre-existing renal disease, patients with conditions that put them at high risk for renal failure, or those receiving potentially nephrotoxic drugs or other diuretics, are at increased risk of renal failure with administration of mannitol. Evaluate the renal, cardiac, and pulmonary status of the patient and correct fluid and electrolyte imbalances prior to administration of Mannitol Injection [see Warnings and Precautions (5.2, 5.3, 5.4, 5.5)].
Signs and symptoms of overdose with Mannitol Injection include renal failure and acute kidney injury, hypo/hypervolemia, hyperosmolarity and electrolyte imbalances, CNS toxicity (e.g., coma, seizures), some of which can be fatal [see Warnings and Precautions (5.2, 5.3, 5.4)].
Management of overdosage with Mannitol Injection is symptomatic and supportive. Discontinue the infusion and institute appropriate corrective measures with particular attention to renal, cardiac, and pulmonary systems. Correct fluid and electrolyte imbalances.
Mannitol Injection is dialyzable (hemodialysis and peritoneal dialysis), hemodialysis may increase mannitol elimination.
Mannitol Injection, USP is a sterile, nonpyrogenic solution of mannitol in water for injection available in a fliptop vial for intravenous administration as an osmotic diuretic.
The content and characteristics are as follows:
|Conc. (%)||g/100 mL||mOsmol/liter (calc.)||pH*|
|25||25||1372||5.9 (4.5 to 7.0)|
The solution contains no bacteriostat, antimicrobial agent, or added buffer (except for pH adjustment) and is intended only as a single-dose injection.
Mannitol, USP is chemically designated D-mannitol (C6H14O6), a white crystalline powder or free-flowing granules freely soluble in water. It has the following structural formula:
Water for Injection, USP is chemically designated H2O.
Mannitol, when administered intravenously, exerts its osmotic diuretic effect as a solute of relatively small molecular size largely confined to the extracellular space. Mannitol hinders tubular reabsorption of water and enhances excretion of sodium and chloride by elevating the osmolarity of the glomerular filtrate.
This increase in extracellular osmolarity affected by the intravenous administration of mannitol will induce the movement of intracellular water to the extracellular and vascular spaces. This action underlies the role of mannitol in reducing intracranial pressure, intracranial edema, and intraocular pressure.
Mannitol distributes largely to the extracellular space within 20 to 40 minutes after intravenous administration. The volume of distribution of mannitol is approximately 17 L in adults.
In subjects with normal renal function, the total clearance is 87 to 109 mL/minute. The elimination half-life of mannitol is 0.5 to 2.5 hours
Only a relatively small amount of the mannitol dose is metabolized after intravenous administration to healthy subjects.
Mannitol is eliminated primarily via the kidneys in unchanged form. Mannitol is filtered by the glomeruli, exhibits less than 10% of tubular reabsorption, and is not secreted by tubular cells. Following intravenous administration, approximately 80% of an administered dose of mannitol is estimated to be excreted in the urine in 3 hours with lesser amounts thereafter.
Patients with Renal Impairment
In patients with renal impairment, the elimination half-life of mannitol is prolonged. In a published study, in patients with renal impairment including acute renal failure and end stage renal failure, the elimination half-life of mannitol was estimated at about 36 hours, based on serum osmolarity. In patients with renal impairment on dialysis, the elimination half-life of mannitol was reduced to 6 and 21 hours during hemodialysis and peritoneal dialysis, respectively [see Use in Specific Populations (8.6), Overdosage (10)].
Mannitol Injection 25%, USP is available as 12.5 g/50 mL (0.25 g/mL) of mannitol in a single-dose vial. Supplied as a tray of 25 vials (NDC 0409-4031-01).
