Nutritional value: approximately 840 kJ/l (or 200 kcal/l)

For the full list of excipients, see section 6.1.

Solution for infusion.

Clear solution, free from visible particles.

Osmolarity 432 mOsm/l (approx)

pH: 3.5 to 6.5

Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution is indicated for:

- Treatment of dehydration or hypovolaemia in cases where supply of water, sodium chloride and carbohydrates is required due to restriction of the intake of fluids and electrolytes by normal routes.

The choice of the specific sodium chloride and glucose concentration, dosage, volume, rate and duration of administration depends on the age, weight, clinical condition of the patient and concomitant therapy. It should be determined by a physician. For patients with electrolyte and glucose abnormalities and for paediatric patients, consult a physician experienced in intravenous fluid therapy.

Fluid balance, serum glucose, serum sodium and other electrolytes should be monitored before and during administration, especially in patients with increased non-osmotic vasopressin release (syndrome of inappropriate antidiuretic hormone secretion, SIADH) and in patients co-medicated with vasopressin agonist drugs due to the risk of hyponatraemia. Monitoring of serum sodium is particularly important for physiologically hypotonic fluids. Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution may become extremely hypotonic after administration due to glucose metabolisation in the body (see sections 4.4, 4.5 and 4.8).

Rapid correction of hyponatraemia and hypernatraemia is potentially dangerous (risk of serious neurologic complications). Electrolyte supplementation may be indicated according to the clinical needs of the patient

Adults, older patients and adolescents (age 12 years and over):

The recommended dosage is 500 ml to 3 L/24h

Administration rate

The infusion rate is usually 40 ml/kg/24h and should not exceed the patient's glucose oxidation capacities in order to avoid hyperglycaemia. Therefore the maximum acute administration rate is 5 mg/kg/min.

Paediatric population

The infusion rate should not exceed the patient's glucose oxidation capacities in order to avoid hyperglycaemia. Therefore the maximum acute administration rate is 10-18 mg/kg/min, depending on the total body mass.

For all patients, a gradual increase of flow rate should be considered when starting administration of glucose containing products.

Method of Administration

The administration is performed by intravenous infusion.

Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution is hypotonic and hyperosmolar, due to the glucose content. It has an approximate osmolarity of 432 mOsm/l

Precautions to be taken before manipulating or administering the product

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Do not administer unless the solution is clear and the seal is intact. Administer immediately following the insertion of infusion set. Do not remove unit from overwrap until ready for use. The inner bag maintains the sterility of the product.

The solution should be administered with sterile equipment using an aseptic technique.

The equipment should be primed with the solution in order to prevent air entering the system. 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.

Additives may be introduced before or during infusion through the resealable medication port. When additive is used, verify tonicity prior to parenteral administration. Hyperosmolar solutions may cause venous irritation and phlebitis. Thus, any hyperosmolar solution is recommended to be administered through a large central vein, for rapid dilution of the hyperosmotic solution.

For further information on the product with additives, please see sections 6.2, 6.3 and 6.6.

The solution is contraindicated in patients presenting with:

• Known hypersensitivity to the product

• Extracellular hyperhydration or hypervolaemia

• Fluid and sodium retention

• Severe renal insufficiency (with oliguria/anuria)

• Uncompensated cardiac failure

• Hyponatraemia or hypochloraemia

• General oedema and ascitic cirrhosis

Clinically significant hyperglycaemia. The solution is also contraindicated in case of uncompensated diabetes, other known glucose intolerances (such as metabolic stress situations), hyperosmolar coma or hyperlactataemia.

Glucose intravenous infusions are usually isotonic solutions. In the body, however, glucose containing fluids can become extremely physiologically hypotonic due to rapid glucose metabolization (see section 4.2).

Depending on the tonicity of the solution, 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 electrolyte disturbances most importantly hypo- or hyperosmotic hyponatraemia.

Hyponatraemia:

The infusion of solutions with sodium concentrations <0.9% may result in hyponatraemia. Close clinical monitoring may be warranted.

Patients with non-osmotic vasopressin release (e.g. in acute illness, pain, post-operative stress, infections, burns, and CNS diseases), patients with heart-, liver- and kidney diseases and patients exposed to vasopressin agonists (see section 4.5) are at particular risk of acute hyponatraemia upon infusion of hypotonic fluids.

Acute hyponatraemia can lead to acute hyponatraemic encephalopathy (brain oedema) characterized by headache, nausea, seizures, lethargy and vomiting. Patients with brain oedema are at particular risk of severe, irreversible and life-threatening brain injury.

Children, women in the fertile age and patients with reduced cerebral compliance (e.g. meningitis, intracranial bleeding, and cerebral contusion) are at particular risk of the severe and life-threatening brain swelling caused by acute hyponatraemia

Sodium retention, fluid overload and oedema

Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution should be used with particular caution, in:

• Patients with conditions that may cause sodium retention, fluid overload and oedema (central and peripheral), such as

o Primary hyperaldosteronism,

o Secondary hyperaldosteronism associated with, for example,

▪ hypertension,

▪ congestive heart failure,

▪ liver disease (including cirrhosis),

▪ renal disease (including renal artery stenosis, nephrosclerosis)

o Pre-eclampsia.

• Patients taking medications that may increase the risk of sodium and fluid retention, such as corticosteroids

Hypokalaemia

The infusion of Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution may result in hypokalaemia. This medicine should be used with particular caution in patients with or at risk for hypokalemia. Close clinical monitoring may be warranted in, for example:

• persons with metabolic alkalosis

• persons with thyrotoxic periodic paralysis, administration of intravenous glucose has been associated in aggravating hypokalaemia

• persons with increased gastrointestinal losses (e.g., diarrhea, vomiting)

• prolonged low potassium diet

• persons with primary hyperaldosteronism

• patients treated with medications that increase the risk of hypokalaemia (e.g. diuretics, beta-2 agonist, or insulin)

Hypo- and hyperosmolality, serum electrolytes and water imbalance

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 Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution can cause:

• Hypo-osmolality

• Hyperosmolality, osmotic diuresis and dehydration

• Electrolyte disturbances such as

o hyponatraemia (see above),

o hypokalaemia (see above),

o hypophosphataemia,

o hypomagnesaemia,

• Overhydration/hypervolaemia and, for example, congested states, including central (e.g., pulmonary congestion) and peripheral oedema.

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.

Hyperglycaemia

Rapid administration of glucose solutions may produce substantial hyperglycaemia and a hyperosmolar syndrome. In order to avoid hyperglycaemia the infusion rate should not exceed the patient's ability to utilize glucose.

To reduce the risk of hyperglycaemia-associated complications, the infusion rate must be adjusted and/or insulin administered if blood glucose levels exceed levels considered acceptable for the individual patient.

Intravenous glucose should be administered with caution in patients with, for example:

• impaired glucose tolerance (such as in diabetes mellitus, renal impairment, or in the presence of sepsis, trauma or shock),

• severe malnutrition (risk of precipitating a refeeding syndrome, see below),

• thiamine deficiency, e.g., in patients with chronic alcoholism (risk of severe lactic

acidosis due to impaired oxidative metabolism of pyruvate),

• water and electrolyte disturbances that could be aggravated by increased glucose and/or free water load

Other groups of patients in whom Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution should be used with caution include:

• patients with ischemic stroke. Hyperglycaemia has been implicated in increasing cerebral ischemic brain damage and impairing recovery after acute ischemic strokes.

• patients with severe traumatic brain injury (in particular during the first 24 hours following the trauma). Early hyperglycaemia has been associated with poor outcomes in patients with severe traumatic brain injury.

• Newborns (see Paediatric glycaemia-related issues).

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

Hypersensitivity Reactions

• Hypersensitivity/infusion reactions, including anaphylaxis, have been reported (see section 4.8).

• Stop the infusion immediately if signs or symptoms of hypersensitivity/infusion reactions develop. Appropriate therapeutic countermeasures must be instituted as clinically indicated.

Solutions containing glucose should be used with caution in patients with known allergy to corn or corn products

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 intake while avoiding overfeeding can prevent these complications.

Severe renal impairment

Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution should be administered with particular caution to patients at risk of (severe) renal impairment. In such patients, administration may result in sodium retention and/or fluid overload.

Paediatric use

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 physician experienced in paediatric intravenous fluid therapy.

Paediatric glycaemia-related issues

• Newborns, especially those born premature and with low birth weight, are at increased risk of developing hypo- or hyperglycaemia. Close monitoring during treatment with intravenous glucose solutions is needed to ensure adequate glycaemic control, in order to avoid potential long term adverse effects.

• Hypoglycaemia in the newborn can cause, e.g.,

o prolonged seizures,

o coma and

o cerebral injury.

• Hyperglycaemia has been associated with

o cerebral injury, including intraventricular haemorrhage,

o late onset bacterial and fungal infection,

o retinopathy of prematurity,

o necrotizing enterocolitis,

o increased oxygen requirements,

o prolonged length of hospital stay and

o death.

Paediatric hyponatraemia-related issues

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

• The infusion of hypotonic fluids together with the non-osmotic secretion of ADH may result in hyponatraemia.

• Hyponatraemia can lead to headache, nausea, seizures, lethargy, coma, cerebral edema and death; therefore, acute symptomatic hyponatraemic encephalopathy is considered a medical emergency.

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

• Rapid correction of 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.

Blood

Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution should not be administered simultaneously with blood through the same administration set because of the possibility of pseudoagglutination or haemolysis.

Geriatric use

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

No studies have been conducted by Baxter.

Both the glycaemic and effects on water and electrolyte balance should be taken into account when administering Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution to patients treated with other substances that affect glycaemic control or fluid and/or electrolyte balance.

Drugs leading to an increased vasopressin effect

The below listed drugs increase the vasopressin effect, leading to reduced renal electrolyte free water excretion and increase the risk of hospital acquired hyponatraemia following inappropriately balanced treatment with i.v. fluids (see sections 4.2, 4.4 and 4.8).

• Drugs stimulating vasopressin release, e.g.: Chlorpropamide, clofibrate, carbamazepine, vincristine, selective serotonin reuptake inhibitors, 3.4-methylenedioxy-N-methamphetamine, ifosfamide, antipsychotics, narcotics

• Drugs potentiating vasopressin action, e.g.: Chlorpropamide, NSAIDs, cyclophosphamide

• Vasopressin analogues, e.g.: Desmopressin, oxytocin, terlipressin

Other medicinal products increasing the risk of hyponatraemia also include diuretics in general and antiepileptics such as oxcarbazepine.

Caution is advised in patients treated with

• lithium. Renal sodium and lithium clearance may be increased during administration and can result in decreased lithium levels.

• corticosteroids, which are associated with the retention of sodium and water (with oedema and hypertension).

• diuretics, beta-2 agonist, or insulin, whom increase the risk of hypokalemia

• certain antiepileptic and psychotropic medications that increase the risk of hyponatraemia.

Pregnancy

Intrapartum maternal intravenous glucose infusion may result in foetal hyperglycaemia and metabolic acidosis as well as rebound neonatal hypoglycaemia due to foetal insulin production.

Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution should be administrated with special caution for pregnant women during labour particularly if administered in combination with oxytocin due to the risk of hyponatraemia (see sections 4.4, 4.5 and 4.8).

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

Frequencies cannot be estimated from the available data as all listed adverse reactions are based on spontaneous reporting

*Potential manifestation in patients with allergy to corn, see section 4.4

** Hospital acquired hyponatraemia may cause irreversible brain injury and death due to development of acute hyponatraemic encephalopathy (see sections 4.2 and 4.4).

Adverse reactions may be associated to the medicinal product(s) added to the solution; the nature of the additive will determine the likelihood of any other adverse reactions.

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

Excess administration of Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution can cause:

• Hyperglycaemia, adverse effects on water and electrolyte balance, and corresponding complications. For example, severe hyperglycaemia and severe dilutional hyponatraemia, and their complications, can be fatal.

• Hyponatraemia (which can lead to CNS manifestations, including seizures, coma, cerebral oedema and death).

• Fluid overload (which can lead to central and/or peripheral oedema).

• See also sections 4.4 and 4.8

When assessing an overdose, any additives in the solution must also be considered.

Clinically significant overdose of Sodium Chloride 0.45 % w/v and Glucose 5.0 % w/v solution may therefore, constitute a medical emergency.

Interventions include discontinuation of administration, dose reduction, administration of insulin and other measures as indicated for the specific clinical constellation.

Pharmacotherapeutic group “Electrolytes with Carbohydrates”,

ATC code: “B05BB02”.

Sodium Chloride 0.45% w/v and Glucose 5.0% w/v is a hypotonic and hyperosmolar solution of sodium chloride and glucose.

The pharmacodynamic properties of Sodium Chloride 0.45% w/v and Glucose 5.0% w/v solution are those of its components (sodium chloride and glucose).

Ions, such as sodium, circulate through the cell membrane, using various mechanisms of transport, among which is the sodium pump (Na⁺/K⁺-ATPase). Sodium plays an important role in neurotransmission and cardiac electrophysiology, and also in its renal metabolism.

Chloride is mainly an extracellular anion. Intracellular chloride is in high concentration in red blood cells and gastric mucosa. Re-absorption of chloride follows re-absorption of sodium.

Glucose is the principal source of energy in cellular metabolism. The glucose in this solution provides a caloric intake of 200kcal/l.

The pharmacokinetic properties of this solution are those of its components (sodium, chloride and glucose).

After injection of radiosodium (²⁴Na), the half-life is 11 to 13 days for 99% of the injected Na and one year for the remaining 1%. The distribution varies according to tissues: it is fast in muscles, liver, kidney, cartilage and skin; it is slow in erythrocytes and neurones; it is very slow in the bone. Sodium is predominantly excreted by the kidneys, but (as described earlier) there is extensive renal re-absorption. Small amounts of sodium are lost in the faeces and sweat.

The two main metabolic pathways of glucose are gluconeogenesis (energy storage) and glycogenolysis (energy release). Glucose metabolism is regulated by insulin.

Preclinical safety data of this solution for infusion in animals are not relevant since its constituents are physiological components of animal and human plasma.

Toxic effects are not to be expected under the condition of clinical application.

The safety of potential additives should be considered separately.
