NAME OF THE MEDICINAL PRODUCT
Mannitol Infusion BP 20%, as Polyfusor M and freeflex
QUALITATIVE AND QUANTITATIVE COMPOSITION
Polyfusor M has the following composition:
For use as an osmotic diuretic, alone or to supplement the action of other diuretics in
order to promote renal function, including the assisted elimination of drugs such as
aspirin and barbiturates.
Posology and Method of Administration
Adults and Children
The volume, strength and rate of infusion of mannitol solutions given in
intravenous will depend upon the requirements of the patient and the
judgement of the physician. A dosage of 200g daily by intravenous infusion
should not be exceeded.
Elderly patients are more susceptible to the adverse effects associated with
mannitol. This is due to diminished renal and cardiac reserves. Elderly
patients should therefore be given a test dose as described below for patients
with renal impairment.
Patients with impaired renal function should be given a test dose of 200 mg
per kilogrambody weight administered over five minutes and if 40 ml or more
of urine is produced in an hour, mannitol may then be given in therapeutic
For intravenous infusion
Mannitol is contraindicated in patients with abnormal capillary fragility,
pulmonary congestion or pulmonary oedema, intracranial bleeding, congestive
heart failure and renal failure unless a test dose has produced a diuretic
Special Warnings and Precautions for Use
Solutions of mannitol given in intravenous infusion should be administered
slowly and should not be mixed with blood in transfusion apparatus. All
patients given mannitol should be observed for signs of fluid and electrolyte
If renal flow is inadequate, water intoxication is likely in patients receiving
intravenous mannitol, therefore its use in oedematous conditions associated
with diminished cardiac reserve should only be considered if the advantages
outweigh the risks.
The label states:
To retard crystallisation store at 20º-30º.
Carefully examine the solution for crystals immediately
before use. If necessary redissolve by raising the
temperature to 60º maintaining it at this temperature,
and shaking occasionally until the crystals have
Cool to blood heat before use.
Interactions with other Medicaments and other forms of Interaction
Mannitol may enhance tubocurarine-induced neuromuscular blockade.
Cyclosporin nephrotoxicity may be enhanced by the concurrent administration
Pregnancy and Lactation
The safety of mannitol infusion has not been established in pregnancy and it
should be used with caution.
The safety in lactation has not been assessed but its use in this period is not
considered to constitute a hazard.
Effects on Ability to Drive and Use Machines
Rapid intravenous infusion of mannitol may produce headache, chills or chest pain. It
may also depress respiration by altering the acid base and electrolyte balance of the
Convulsions have been known in patients administered excessive doses of mannitol
Other side effects reported may be associated with hypersensitivity reactions.
Treatment of overdosage with mannitol should be symptomatic and, particular,
directed at correction of fluid and electrolyte imbalance.
Mannitol is an osmotically active solute which is filtered at the glomerulus, and
produces a corresponding increase in urine volume.
Preclinical Safety Data
List of excipients
Water for Injections in bulk
Mannitol should not be mixed with blood because of possible agglutination
and irreversible crenation.
Electrolyte solutions should not be added to mannitol infusions, since addition
is likely to salt out the mannitol.
Other drugs which are incompatible with mannitol solutions include;
corticotrophin, soluble barbiturates, noradrennaline, metaraminol,
suxamethonium and tetracyclines.
