Supplement of water, carbohydrates and electrolytes to patients where normal intake is insufficient or when there is a deficiency.

Posology

Dosage, rate, and duration of administration are to be individualised and depend upon the indication for use, the patient’s age, weight, clinical condition, and concomitant treatment, and on the patient’s clinical and laboratory response to treatment.

Recommended dose for adults is 2-3 litres infusion fluid per day.

Glucose-Na-K Baxter 50 mg/ml solution for infusion: 1000 ml administered intravenously during 4 -12 hours (based on a patient weighing 70 kg).

Infusion rate: 1.2 – 3.5 ml/kg/hour.

Buffering capacity: In order to increase pH of Glucose-Na-K Baxter 50 mg/ml from 5 to 7, approximately 7 mmol NaOH will be needed. In order to decrease the pH of Glucose-Na-K Baxter 50 mg/ml from 5 to 4, approximately 13 mmol HCl will be needed.

Infusion rate should not exceed the patient’s glucose oxidation capacities in order to avoid hyperglycemia. For information, the maximum glucose oxidation capacities is 5mg/kg/min for adults.

Paediatric population:

Currently, there are no dosing recommendations for use in children (Please see section 4.4: Use in pediatric patients).

Method of administration:

The solution should be administered by intravenous infusion (peripheral or central vein). Glucose-Na-K Baxter 50 mg/ml solution for infusion must not be administered subcutaneously.

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.

Because of the presence of glucose, this solution should NOT be administered through the same infusion equipment as whole blood, as haemolysis and clumping of the blood cells can occur.

The solution is contra-indicated in patients presenting:

• Hyperkalaemia

• Severe renal insufficiency (with oliguria/anuria)

• Uncompensated cardiac or pulmonary failure

• The solution is also contraindicated in case of uncontrolled diabetes, other known glucose intolerances, hyperosmolar coma, hyperglycemia, hyperlactatemia.

• Hypersensitivity to the active substance(s) or to any of the excipients listed in section 6.1

WARNINGS

Fluid balance/renal function

Risk of fluid and/or solute overload and electrolyte disturbances

The patient’s clinical status and laboratory parameters (fluid balance, blood and urine electrolytes as well as acid-base balance) must be monitored during use of this solution.

Depending on the volume and rate of infusion, intravenous administration of Glucose-Na-K Baxter 50 mg/ml solution can cause fluid and/or solute overload resulting in overhydration/hypervolemia therefore high volume infusion must be used under specific monitoring in patients with cardiac, pulmonary or renal failure.

Use in patients with hypervolaemia or overhydration, or conditions that cause sodium retention and oedema

Glucose-Na-K Baxter 50 mg/ml solution should be administered with particular caution to hypervolaemic or overhydrated patients. Solutions containing sodium chloride should be carefully administered to patients with hypertension, heart failure, peripheral or pulmonary oedema, impaired renal function, pre-eclampsia, aldosteronism, or other conditions associated with sodium retention (see also 4.5).

Use in patients with severe renal impairment

Glucose-Na-K Baxter 50 mg/ml solution should be administered with particular caution to patients with severe renal impairment. In such patients administration of Glucose-Na-K Baxter 50 mg/ml solution may result in sodium and/or potassium or magnesium retention.

Electrolyte balance

Glucose-Na-K Baxter 50 mg/ml solution should be administered with particular caution to patients with alkalosis or at risk for alkalosis. Excess administration of Glucose-Na-K Baxter 50 mg/ml solution can result in metabolic alkalosis because of the presence of acetate ions. However, this solution is not suitable to treat severe metabolic or respiratory acidosis.

Glucose-Na-K Baxter 50 mg/ml solution's magnesium concentration is inadequate for the treatment of symptomatic hypomagnesemia.

Use in patients with or at risk for and from hyperkalemia

The plasma potassium level of the patient should be particularly closely monitored in patients at risk of hyperkalaemia. Solutions containing potassium salts should be administered with caution to patients with cardiac disease or conditions predisposing to hyperkalemia such as renal or adrenocortical insufficiency, acute dehydration, or extensive tissue destruction as occurs with severe burns.

Use in patients with hypocalcemia

Glucose-Na-K Baxter 50 mg/ml solution contains no calcium, and an increase in plasma pH due to its alkalinizing effect may lower the concentration of ionized (not protein-bound) calcium. Glucose-Na-K Baxter 50 mg/ml solution should be administered with particular caution to patients with hypocalcemia

Use in patients with or at risk for and from hypermagnesemia

Solutions containing magnesium salts should be used with caution to patient with renal impairment, severe heart rate disorders and in patients with myasthenia gravis. Patients should be monitored for clinical signs of excess magnesium, particularly when being treated for eclampsia (see also in 4.5 “Interactions with other medicinal products and other forms of interaction”).

Acid base balance

Use in patients with or at risk for alkalosis

Glucose-Na-K Baxter 50 mg/ml solution should be administered with particular caution to patients with alkalosis or at risk for alkalosis. Excess administration of Glucose-Na-K Baxter 50 mg/ml solution can result in metabolic alkalosis because of the presence of acetate ions. However, this solution is not suitable to treat severe metabolic or respiratory acidosis.

Other warnings

Hypersensitivity reactions

Hypersensitivity/infusion reactions, including anaphylactoid reactions, have been reported with Glucose-Na-K Baxter 50 mg/ml solution.

The infusion must be stopped immediately if any signs or symptoms of a suspected hypersensitivity reaction develop. Appropriate therapeutic counter measures must be instituted as clinically indicated.

Solutions containing glucose should be used with caution in patients with known allergy to corn or corn products, see section 4.8”.

Administration in the postoperative period after neuromuscular block should be used with caution since magnesium salts can lead to a recurring effect.

For patients who are severely malnourished or have undergone a long period of starvation, caution should be exercised initially when administering glucose. The dose may be gradually increased as glucose metabolism improves. During long-term parenteral treatment, other convenient nutritive supply must be given to the patient.

PRECAUTIONS

Use in patients with or at risk for hyperglycemia

Solutions containing glucose should be used with caution in patients with impaired glucose tolerance or diabetes mellitus. In diabetic patients, the amount of infused glucose has to be taken into account and insulin requirements may be modified. If hyperglycemia occurs, rate of infusion should be adjusted or insulin administered.

Due to glucose presence, this solution is contra-indicated in the first 24 hours following head trauma and blood glucose concentration should be closely monitored during intracranial hypertension episodes.

Hyperglycemia has been implicated in increasing cerebral ischemic brain damage and impairing recovery after acute ischemic strokes. Caution is recommended in using dextrose-containing solutions in such patients.

Osmolarity

Glucose-Na-K Baxter 50 mg/ml solution for infusion is an hypertonic solution of electrolytes and glucose (osmolarity: 402 mOsm/l (approx)).

Administration of hypertonic solutions may cause venous irritation, including phlebitis.

Hyperosmolar solutions should be administered with caution to patients with hyperosmolar states.

Use in pediatric patients

Safety and effectiveness of Glucose-Na-K Baxter 50 mg/ml solution in children have not been established by adequate and well-controlled trials.

The 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 pediatric intravenous fluid therapy.

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

Plasma electrolyte concentrations should be closely monitored in the paediatric population as this population may have impaired ability to regulate fluids and electrolytes.

The infusion of low sodium containing fluids together with the non-osmotic secretion of ADH may result in hyponatremia. Hyponatremia can lead to headache, nausea, seizures, lethargy, coma, cerebral oedema and death. Therefore, acute symptomatic hyponatremic encephalopathy is considered a medical emergency.

Use in elderly

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

Interaction with sodium:

Interaction with potassium:

• Potassium-sparing diuretics (amiloride, spironolactone, triamterene, alone or in association).

• Angiotensin converting enzyme inhibitors (ACEi) and angiotensin II receptor antagonists.

• Tacrolimus and cyclosporine increase concentration of potassium in the plasma and the combination may lead to potentially fatal hyperkalemia notably in case of a renal failure contributing to the hyperkalemia.

Interaction with acetate:

Caution is advised when administering Glucose-Na-K Baxter 50 mg/ml solution to patients treated with drugs for which renal elimination is pH dependent. Due to its alkalinizing effect (formation of bicarbonate), Glucose-Na-K Baxter 50 mg/ml solution may interfere with the elimination of such drugs.

• Renal clearance of acidic drugs such as salicylates, barbiturates and lithium may be increase because of the alkalinisation of urine by the bicarbonate resulting from acetate and gluconate metabolism.

• Renal clearance of alkaline drugs, notably such as sympathomimetics (e.g. ephedrine, pseudoephedrine) and stimulants (e.g. quinidine, dexamphetamine sulphate, phenfluramine hydrochloride) may be decreased.

Interactions with magnesium

Intrapartum maternal intravenous infusion of glucose containing solutions may result in fetal insulin production, with an associated risk of fetal hyperglycemia and metabolic acidosis as well as rebound hypoglycemia in the neonate. Physicians should carefully consider the potential risks and benefits for each specific patient before administering Glucose-Na-K Baxter 50 mg/ml solution.

Glucose-Na-K Baxter 50 mg/ml solution has no or negligible influence on the ability to drive or use machines.

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 national reporting system listed in [To be completed nationally].

Too fast infusion may lead to water and sodium overload with a risk of oedema, particularly when there is a defective renal sodium excretion. In this case renal dialysis may be necessary.

Excessive administration or rapid infusion or prolonged administration of glucose may lead to hyperglycemia.

Excessive administration of potassium may lead to the development of hyperkalemia, especially in patients with renal impairment. Symptoms include paresthesia of the extremities, muscle weakness, paralysis, cardiac arrhythmias, heart block, cardiac arrest, and mental confusion. Treatment of hyperkalemia involves the administration of calcium, insulin (with glucose) sodium bicarbonate, exchange resins or dialysis.

Excessive administration of magnesium may lead to hypermagnesemia.

Excessive administration of compounds, such as sodium acetate, which are metabolized to form the bicarbonate anion may lead to hypokalemia and metabolic alkalosis, especially in patients with impaired renal function. Symptoms may include mood changes, tiredness, shortness of breath, muscle weakness, and irregular heartbeat. Muscle hypertonicity, twitching, and tetany may develop especially in hypocalcemic patients. Treatment of metabolic alkalosis associated with bicarbonate overdose consists mainly of appropriate correction of fluid and electrolyte balance.

Acute treatment:

The infusion should be interrupted immediately. Administration of diuretics and continuous monitoring of serum electrolytes, correction of electrolyte balance and acid-base balance.

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

The effects of an overdose may require immediate medical attention and treatment.
