Clinical Particulars

Therapeutic Indications

Glycophos is indicated in adult patients and infants as a supplement in intravenous nutrition to meet the requirements of phosphate.

Posology and Method of Administration

Glycophos must not be given undiluted.


The recommended dosage is individual. The recommended daily dosage of phosphate during intravenous nutrition would normally be 10-20 mmol. This can be met by using 10-20 ml of Glycophos added to the infusion solution or to the admixture for which compatibility has been proved.


The recommended dosage is individual. The recommended dose for infants and neonates is 1.0-1.5 mmol/Kg body weight/day.


Glycophos should not be given to patients in a state of dehydration or with hypernatraemia, hyperphosphataemia, severe renal insufficiency or shock.

Special Warnings and Special Precautions for Use

Glycophos should be used with caution in patients with impaired renal function. The phosphate status of all patients should be monitored regularly.

Glycophos must not be given undiluted.

Interaction With Other Medicaments and Other Forms of Interaction

No interactions with other drugs have been observed, but a moderate fall in serum phosphate can be seen during carbohydrate infusions.

Pregnancy and Lactation

Animal reproduction studies or clinical investigations during pregnancy have not been carried out with Glycophos. However, the requirements of phosphate in a pregnant woman are slightly increased compared to non-pregnant women.

No adverse events are to be expected when Glycophos is administered during pregnancy.

Effects on Ability to Drive and Use Machines

No effects on the ability to drive and use machines are to be expected.

Undesirable Effects

No adverse effects related to glycerophosphate have been reported.


No adverse effects of an overdose have been reported. Most patients in need of intravenous nutrition have an increased capacity to handle glycerophosphate. See also "Contra-indications".

Pharmacological Properties

Pharmacodynamic Properties

Glycerophosphate is a metabolic intermediate in fat metabolism and any pharmacodynamic effects other than maintaining the normal metabolic pathways are unlikely.

Pharmacokinetic Properties

To become available it is necessary for the phosphate group to be hydrolysed from the glycerophosphate molecule. The hydrolysis occurs maximally at a plasma concentration of >0.7 mmol/l. Assuming that all hydrolysis of glycerophosphate takes place in plasma, about 12-15 mmol of sodium glycerophosphate will be hydrolysed each day in individuals with normal serum alkaline phosphatase.

No pharmacokinetical data is available for infants, however with the recommended dosage hyperphosphataemia is unlikely.

Preclinical Safety Data

Preclinical safety studies on Glycophos demonstrated good tolerance.
