Glucose

Glucose 70% w/v Concentrate for solution for infusion.

For the full list of excipients, see Section 6.1.

Concentrate for solution for infusion.Clear, slightly yellow solution.Glucose 70% w/v has an osmolarity of 3885 mOsmol/L.

Glucose 70% w/v is for use in admixtures to provide temporary relief from the symptoms of increased intracranial pressure and hypoglycaemic coma and is also indicated for the supplementation of energy in parenteral nutrition.

Posology

The dosage and rate of administration of Glucose 70% w/v are determined by several factors including the indication for use and the patient's age, weight and clinical condition.

Method of administration

Glucose 70% w/v is for administration by intravenous infusion following appropriate dilution or incorporation in to a parenteral nutrition admixture.

Administration of hyperosmolar solutions may cause venous irritation and phlebitis.

The resultant admixture should be administered through a central or peripheral venous line depending on its final osmolarity. If the final mixture, to be administered, is hypertonic it may cause irritation of the vein when administered into a peripheral vein.The infusion rate and volume depends on the age, weight, clinical and metabolic conditions of the patient, as well as concomitant therapy.A gradual increase of flow rate should be considered when starting administration of glucose-containing products.To reduce the risk of hypoglycaemia after discontinuation, a gradual decrease in flow rate before stopping the infusion should be considered.Electrolyte supplementation may be indicated according to the clinical needs of the patient.As indicated on an individual basis, vitamins and trace elements and other components (including amino acids and lipids) can be added to the parenteral regimen to meet nutrient needs and prevent deficiencies and complications from developing.

Dilute Glucose 70% w/v before use to a concentration which will, when administered with an amino acid (nitrogen) source, result in an appropriate calorie to gram of nitrogen ratio and which has an osmolarity consistent with the route of administration.

When Glucose 70% w/v is used in conjunction with amino acids, the rate of administration of glucose should not exceed 1g/kg/hour for optimal protein anabolism.Use in Paediatric PatientsThe infusion rate and volume depends on the age, weight, clinical and metabolic conditions of the patient, concomitant therapy and should be determined by the consulting physician experienced in paediatric intravenous fluid therapy (see section 4.4).

Contra-indicated in patients with:• Hypersensitivity to the active substance or to any of the excipients listed in section 6.1. See sections 4.4 and 4.8 for corn allergies• Clinically significant hyperglycaemia

WARNINGSNot for direct intravenous infusion. Must be appropriately diluted before use. The admixture obtained should be administered through a central or peripheral venous line depending on its final osmolarity.Unless appropriately diluted infusion of hypertonic glucose solutions into a peripheral vein may result in vein irritation, vein damage, and thrombosis. Strongly hypertonic solutions should only be administered through an indwelling intravenous catheter with the tip located in a large vein such as the superior vena cava. Prolonged intravenous infusion of this solution may cause thrombophlebitis extending from the site of infusion.

Dilution and other effects on serum electrolytes

Depending on the volume and rate of infusion and depending on a patient's underlying clinical condition and capability to metabolize glucose, intravenous administration of glucose can cause:• Hyperosmolality, osmotic diuresis and dehydration• Hypoosmolality• Electrolyte disturbances such as:- hyponatraemia (see below),- hypokalaemia,- hypophosphatemia,- hypomagnesaemia,- overhydration/hypervolemia and, for example, congested states, including pulmonary congestion and oedema.The above effects do not only result from the administration of electrolyte-free fluid but also from glucose administration. Hyponatraemia can develop into acute hyponatraemic encephalopathy characterized by headache, nausea, seizures, lethargy, coma, cerebral oedema, and death. Children, the elderly, women, postoperative patients, patients with hypoxia and patients with central nervous system disease or psychogenic polydipsia are at particular risk for this complication.Clinical evaluation and periodic laboratory determinations may be necessary to monitor changes in fluid balance, electrolyte concentrations, and acid-base balance during prolonged parenteral therapy or whenever the condition of the patient or the rate of administration warrants such evaluation.Particular caution is advised in patients at increased risk of water and electrolyte disturbances that could be aggravated by increased free water load, hyperglycaemia or possibly required insulin administration (see below).

Hyperglycaemia

As with the intravenous administration of nutrients (e.g., glucose, amino acids and lipids) in general, metabolic complications may occur if the nutrient intake is not adapted to the patient's requirements, or the metabolic capacity of any given dietary component is not accurately assessed. Adverse metabolic effects may arise from administration of inadequate or excessive nutrients or from inappropriate composition of an admixture for a particular patient's needs.Rapid administration of glucose solutions may produce substantial hyperglycaemia and a hyperosmolar syndrome.To reduce the risk of hyperglycaemia-associated complications, the infusion rate must be adjusted and/or insulin administered.Intravenous glucose should be administered with caution in patients with, for example:- impaired glucose tolerance (such as in patients with renal failure or diabetes mellitus, or in the presence of sepsis, trauma, or shock),- severe malnutrition (risk of precipitating a refeeding syndrome),- thiamine deficiency, e.g., in patients with chronic alcoholism (risk of severe lactic acidosis due to impaired oxidative metabolisation of pyruvate),- water and electrolyte disturbances that could be aggravated by increased glucose and/or free water load (see above).- patients with ischemic stroke or severe traumatic brain injury- avoid infusion within the first 24 hours following head trauma. Monitor blood glucose closely as early hyperglycaemia has been associated with poor outcomes in patients with severe traumatic brain injury.- newborns (see below).

Effects on Insulin Secretion

Prolonged intravenous administration of glucose and associated hyperglycaemia may result in decreased rates of glucose-stimulated insulin secretion.

Hypersensitivity Reactions

Hypersensitivity/infusion reactions, including anaphylactic/anaphylactoid reactions, have been reported (see section 4.8).Solutions containing glucose should be used with caution, if at all, in patients with known allergy to corn or corn products.The infusion must be stopped immediately if any signs or symptoms of a suspected hypersensitivity reaction develop. Appropriate therapeutic countermeasures must be instituted as clinically indicated.

Refeeding syndrome

Refeeding severely undernourished patients may result in the refeeding syndrome that is characterized by the shift of potassium, phosphorus, and magnesium intracellularly as the patient becomes anabolic. Thiamine deficiency and fluid retention may also develop. Careful monitoring and slowly increasing nutrient intakes while avoiding overfeeding can prevent these complications.

Liver disorders

Hepatobiliary disorders including cholestasis, hepatic steatosis, fibrosis and cirrhosis, possibly leading to hepatic failure, as well as cholecystitis and cholelithiasis are known to develop in some patients on parenteral nutrition. The etiology of these disorders is thought to be multifactorial and may differ between patients. Patients developing abnormal laboratory parameters or other signs of hepatobiliary disorders should be assessed early by a clinician knowledgeable in liver diseases in order to identify possible causative and contributory factors, and possible therapeutic and prophylactic interventions.

Catheter infection and sepsis

Infection and sepsis may occur as a result of the use of intravenous catheters to administer parenteral formulations, poor maintenance of catheters or contaminated solutions.Immunosuppression and other factors such as hyperglycaemia, malnutrition and/or their underlying disease state may predispose patients to infectious complications.Careful symptomatic and laboratory monitoring for fever/chills, leukocytosis, technical complications with the access device, and hyperglycaemia can help recognize early infections.The occurrence of septic complications can be decreased with heightened emphasis on aseptic technique in catheter placement, maintenance, as well as aseptic technique in nutritional formula preparation.

Precipitates

Pulmonary vascular precipitates have been reported in patients receiving parenteral nutrition. In some cases, fatal outcomes have occurred. Excessive addition of calcium and phosphate increases the risk of the formation of calcium phosphate precipitates. Precipitates have been reported even in the absence of phosphate salt in the solution.In addition to inspection of the solution, the infusion set and catheter should also periodically be checked for precipitates.If signs of pulmonary distress occur, the infusion should be stopped and medical evaluation initiated.

Paediatric population

The infusion rate and volume depends on the age, weight, clinical and metabolic conditions of the patient, concomitant therapy, and should be determined by a consulting physician experienced in paediatric intravenous fluid therapy.In order to avoid potentially fatal over infusion of intravenous fluids to the neonate, special attention needs to be paid to the method of administration. When using a syringe pump to administer intravenous fluids or medicines to neonates, a bag of fluid should not be left connected to the syringe.When using an infusion pump all clamps on the intravenous administration set must be closed before removing the administration set from the pump, or switching the pump off. This is required regardless of whether the administration set has an anti-free flow device.The intravenous infusion device and administration equipment must be frequently monitored.

Paediatric glycaemia related issues

Newborns, especially those born premature and with low birth weight - are at increased risk of developing hypo- or hyperglycaemia and therefore need close monitoring during treatment with intravenous glucose solutions to ensure adequate glycaemic control in order to avoid potential long term adverse effects. Hypoglycaemia in the newborn can cause prolonged seizures, coma and brain damage. Hyperglycaemia has been associated with intraventricular haemorrhage, late onset bacterial and fungal infection, retinopathy of prematurity, necrotizing enterocolitits, bronchopulmonary dysplasia, prolonged length of hospital stay, and death.

Paediatric hyponatraemia-related issues

Children (including neonates and older children) are at increased risk of developing hypoosmotic hyponatraemia as well as for developing hyponatraemic encephalopathy.

Plasma electrolyte concentrations should be closely monitored in the paediatric population.

Rapid correction of hypoosmotic hyponatraemia is potentially dangerous (risk of serious neurologic complications). Dosage, rate, and duration of administration should be determined by a physician experienced in paediatric intravenous fluid therapy.

Geriatric Use

When selecting the type of infusion solution and the volume/rate of infusion for a geriatric patient, consider that geriatric patients are generally more likely to have cardiac, renal, hepatic impairment, and other diseases or concomitant drug therapy.

Blood

Glucose solution (an aqueous, i.e., electrolyte-free glucose solution) should not be administered through the same equipment as whole blood, as haemolysis and pseudoagglutination can occur.

Both the glycaemic effects of intravenous glucose and its effects on water and electrolyte balance should be taken into account when using intravenous glucose in patients treated with other substances that affect glycaemic control, or fluid and/or electrolyte balance.

Intrapartum maternal intravenous glucose infusion may result in foetal insulin production, with an associated risk of foetal hyperglycaemia and metabolic acidosis as well as rebound hypoglycaemia in the neonate.

Pregnancy

Glucose solution can be used during pregnancy. However, caution should be exercised when glucose solution is used intrapartum.

Fertility

There are no adequate data of the effect of Glucose on fertility.

Lactation

There are no adequate data of using Glucose solution during lactation. Glucose solutions have been used during lactation.

There is no information on the effects of intravenous glucose on the ability to operate a vehicle or other heavy machinery.

The following adverse reactions have been reported in the post-marketing experience, listed by MedDRA System Organ Class (SOC), then, where feasible, by Preferred Term in order of severity.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme. Website: www.mhra.gov.uk/yellowcard

Use of an in-line filter is recommended during administration of all parenteral solutions where possible.

Single use only.

Do not store partially used bags.

Discard any unused portion, waste materials and all associated devices.

Risk of Air Embolism

Do not use plastic containers in series connections. Such use could result in air embolism due to residual air being drawn from the primary container before the administration of the fluid from the secondary container is completed.

Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration.

Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers.
