Potassium Chloride 0.15 % w/v and Glucose 10 % w/v Solution for Infusion BP

Potassium Chloride 0.15 % w/v and Glucose 10 % w/v Solution for Infusion is used in adults, the elderly, adolescents, children and infants (aged 28 days to 23 months) for:

• Prevention and treatment of potassium depletion and/or hypokalemia in cases where supply of water, potassium chloride and carbohydrates is required due to restriction of the intake of fluids and electrolytes by normal routes.

• Supply of carbohydrate and potassium during parenteral nutrition.

• Prevention and treatment of hypoglycaemia.

• Rehydration in case of water loss and dehydration states in patients with high carbohydrate need.

The choice of specific potassium chloride and glucose concentration, dosage, volume, rate and duration of administration depends on the age, weight, and clinical conditions of the patient, concomitant therapy, and administration 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.

The dose of potassium may be expressed in terms of mEq or mmol of potassium, mass of potassium or mass of potassium salt:

1g KCl = 525 mg of K+ or 13.4 mEq or 13.4 mmol of K+ and Cl- .

1 mmol K+ = 39.1 mg K+

General Posology

Adults and the elderly:

The recommended doses in Table 1 serve as a guideline for an average adult with a body weight of approximately 70 kg.

The infusion rate should not exceed the patient's glucose oxidation capacities in order to avoid hyperglycaemia. Therefore the maximum acute administration rate for adults and the elderly is 5 mg/kg/min (3 ml/kg/h).

Table 1

Guidance on the dose for administration to an adult (70 kg) (*)

*The largest volumes within recommended dose should be administered in 24 hours to avoid haemodilution.

** The dosage given under “ General Posology” should not be exceeded.

Patients with renal impairment

Patients with renal impairment should receive lower doses.

Use in Paediatric Population: The recommended doses in Table 2 serve as a guideline for infants, toddlers, children and adolescents, as a function of body weight and age.

The infusion rate should not exceed the patient's glucose oxidation capacities in order to avoid hyperglycaemia. Therefore the maximum acute administration rate for infants, toddlers, children and adolescents is 10-18 mg/kg/min (6-11 ml/kg/h) depending on the age and the total body mass.

Table 2

Guidance on the dose for administration to infants, toddlers, children and adolescents (*)

*The largest volumes within recommended dose should be administered in 24 hours to avoid haemodilution.

** The dosage given under “ General Posology” should not be exceeded.

Note:

Infants and toddlers: age ranges from about 28 days to 23 months. A toddler is an infant who can walk).

Children: age ranges from about 2 years to 11 years.

Depending on the patient^'s clinical condition, a lower flow rate than recommended can be used in order to decrease the risk of undesirable osmotic diuresis.

When the solution is used for dilution or delivery of compatible therapeutic additives for administration intravenously, the directions for use of the additive therapeutic substances will dictate the appropriate volumes for each therapy.

Administration

Route of administration:

The solution is for administration by intravenous infusion using sterile and non-pyrogenic equipment. The solution contains potassium and should be administered via a large peripheral or central vein to diminish the risk of causing sclerosis. If infused through central vein, be sure the catheter is not in the atrium or ventricle to avoid localized hyperkalaemia.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not administer unless the solution is clear and the seal is intact (refer to section 6.6 Special precaution for disposal and other handling). Administer immediately following the insertion of infusion set.

When making additions, the final osmolarity of the mixture must be measured before administration. The mixture obtained must be administered through a central or peripheral venous line depending on its final osmolarity. The instructions for use of the medication to be added and other relevant literature must be consulted (refer to section 6.6 Special precaution for disposal and other handling).

For information on incompatibilities and preparation of the product and additives, please see sections 6.2 and 6.6.

Rate of administration:

Solutions containing potassium should be administered slowly. As administered intravenously, potassium should not be given faster than 15 to 20 mmoles/h to avoid dangerous hyperkalaemia. A gradual increase of flow rate should be considered when starting administration of glucose-containing products.

Monitoring:

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.

Potassium Chloride 0.15 % w/v and Glucose 10% 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).

Adequate urine flow must be ensured.

Treatment should be carried out under regular and careful surveillance. Clinical and biological parameters, in particular fluid balance and the concentrations of glucose and electrolytes (especially potassium) in plasma must be monitored during administration. Higher dosage or high speed infusion must be performed under ECG control. Electrolyte supplementation may be indicated according to the clinical needs of the patient.

The solution is contraindicated in patients presenting with:

• Known hypersensitivity to the product

• Hyperkalaemia

• Hyperchloremia that is not related to the concentration effect associated to a volume depletion

• Clinically significant hyperglycaemia

• Uncompensated diabetes and diabetes insipidus

• Hyperosmolar coma

• Haemodilution and extracellular hyperhydration or hypervolaemia

• Hyperlactataemia

• Severe renal insufficiency (with oliguria / anuria)

• Uncompensated cardiac failure

• General oedema (including pulmonary and brain oedema) and ascitic cirrhosis

• Other known glucose intolerances (such as metabolic stress situations)

• Addision's disease.

The contraindications related to any medicinal product that is added to the glucose solution should be considered.

Potassium Chloride 0.15 % w/v and Glucose 10 % w/v Solution for Infusion is a hypertonic solution with an approximate osmolarity of 595 mOsm/l.

High volume infusion must be used under specific monitoring in patients with cardiac, pulmonary or renal failure.

Regular monitoring of clinical status, blood glucose level, plasma electrolyte concentrations, plasma creatinine levels, BUN level, acid-base balance and ECG is essential in patients receiving potassium therapy, particularly those with cardiac or renal impairment.

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.

As glucose tolerance may be impaired in patients with diabetes, renal failure or acute critical illness, clinical and biological parameters, in particular plasma-electrolytes including magnesaemia or phosphatemia and glycaemia should be particularly closely monitored. If hyperglycaemia occurs, the rate of infusion should be adjusted or insulin should be administered.

Administration of solutions containing glucose may lead to decreased concentrations of potassium in the plasma. Therefore, potassium solutions containing glucose should not be used for the initial correction of hypokalaemia.

Do not use plastic containers connected in series. 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.

Special clinical monitoring is required at the beginning of any intravenous infusion.

Blood

Potassium Chloride 0.15% w/v and Glucose 10% w/v Solution should not be administered simultaneously with blood through the same administration set because of the possibility of pseudoagglutination or haemolysis.

Hyponatraemia

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

Rapid correction of hyponatremia may cause serious neurologic complications, in particular in paediatric patients (see Paediatric Use).

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

Potassium Chloride 0.15% w/v and Glucose 10% w/v solution may cause:

• Hypo-osmolality

• Hyperosmolality, osmotic diuresis and dehydration

• Electrolyte disturbances such as

o Hyponatraemia (see Hyponatraemia),

o Hypophosphatemia,

o Hypomagnesemia,

• Acid-base imbalance

• Overhydration/hypervolemia and, for example, congested states, including central (e.g., pulmonary congestion) and peripheral edema. Particular caution should be taken in patients with conditions that may cause sodium retention, fluid overload, and edema (central and peripheral).

• Hyponatremia and a decrease in extracellular sodium concentrations related to hyperglycaemia causing a transcellular shift of water.

• Infusion of Potassium Chloride 0.15% w/v and Glucose 10% w/v solution corresponds to the increasing body's load of free water, possibly leading to hypoosmotic hyponatremia.

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 and from water and electrolyte disturbances that could be aggravated by increased free water load.

Hyperglycaemia

Rapid administration of glucose solutions may produce substantial hyperglycaemia and 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),

• 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 Potassium Chloride 0.15% w/v and Glucose 10% 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.

Hyperkalaemia

Caution should be taken to patients with conditions predisposing to hyperkalaemia and/or associated with increased sensitivity to potassium, such as patients with:

• acute dehydration,

• extensive tissue injury or burns,

• certain cardiac disorders such as congestive heart failure or atrioventricular (AV) block (especially if they receive digitalis),

• potassium-aggravated skeletal muscle channelopathies (e.g., Hyperkalaemic periodic paralysis, paramyotonia congenita, and potassium-aggravated myotonia/paramyotonia).

• Renal or adrenocortical insufficiency

Caution should be taken to patients who are at risk of experiencing hyperosmolality, acidosis, or undergoing correction of alkalosis (conditions associated with a shift of potassium from intracellular to extracellular space) and patients treated concurrently or recently with agents or products that can cause hyperkalaemia (see Interactions with Other Medicinal Products and Other Forms of Interaction, Section 4.5).

Caution should be taken for patients with cardiac arrhythmia. Arrhythmias can develop at any time during hyperkalaemia. Frequently, mild or moderate hyperkalaemia is asymptomatic and may be manifested only by increased serum potassium concentrations and, possibly, characteristic ECG changes.

Hypokalaemia

The infusion Potassium Chloride 0.15% w/v and Glucose 10% w/v solution may result in hypokalaemia. Hypokalaemia can lead to arrhythmias, muscle weakness, paralysis, heart block, and rhabdomyolysis.

Potassium Chloride 0.15% w/v and Glucose 10% w/v solution should be used with particular caution, warranting close clinical monitoring, for example:

• in persons with metabolic alkalosis,

• in persons with thyrotoxic or hypokalemic periodic paralysis,

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

• in persons on prolonged low potassium diet (e.g., undernourished or cachectic patients),

• in persons with primary hyperaldosteronism,

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

Hypersensitivity Reactions

Hypersensitivity/infusion reactions, including anaphylaxis, have been reported with Potassium Chloride 0.15% w/v and Glucose 10% w/v Solution (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.

Use in Patients at risk of Severe Renal Impairment

Potassium Chloride 0.15% w/v and Glucose 10% w/v Solution should be administered with particular caution, to patients at risk of severe renal impairment.

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 consulting 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 (see section 4.6).

• 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 intra-ventricular 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

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.

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

• 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.

Elderly Use

When selecting the type of infusion solution and the volume/rate of infusion for an elderly patient, consider that elderly 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 effects and its effects on water and electrolyte balance should be taken into account when using Potassium Chloride 0.15% w/v and Glucose 10% w/v Solution in patients treated with other substances that affect glycaemic control, or fluid and/or electrolyte balance.

Potassium Chloride 0.15% w/v and Glucose 10% w/v Solution should be used with caution in patients treated concurrently or recently with agents or products that can cause Hyperkalaemia or increase the risk of hyperkalaemia, such as potassium sparing diuretics (e.g. amiloride, spironolactone, triamterene) corticosteroids, ACE inhibitors, ciclosporin, tacrolimus and drugs that contain potassium.

Administration of potassium in patients treated with such agents is associated with an increased risk of severe and potentially fatal hyperkalaemia, in particular in the presence of other risk factors for hyperkalaemia.

Regarding medications that increase the risk of hyponatraemia or sodium and fluid retention, such as corticosteroids, see Special Warnings and Precautions for Use.

Interaction related to the presence of glucose:

Concomitant administration of catecholamines and steroids decreases the glucose up-take.

Glucose should not be administered through the same infusion equipment as whole blood as haemolysis and clumping can occur.

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.

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 (see paediatric use).

Potassium Chloride 0.15 % w/v and Glucose 10% 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 section 4.4, 4.5 and 4.8).

Hyperkalemic and hypokalemic serum levels lead to impaired cardiac function of the maternal and foetal hearts. Therefore, the maternal electrolyte levels are to be controlled regularly.

Fertility

Excess administration of Potassium Chloride 0.15% w/v and Glucose 10% 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 edema and death).

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

• Hyperkalaemia, if hyperkalaemia is present or suspected, discontinue the infusion immediately and institute close ECG, laboratory and other monitoring and, as necessary, corrective therapy to reduce serum potassium levels. Manifestations of hyperkalaemia may include:

- disturbances in cardiac conduction and arrhythmias, including bradycardia, heart block, asystole, ventricular tachycardia, ventricular fibrillation

- hypotension

- muscle weakness up to and including muscular and respiratory paralysis, paresthesia of extremities gastrointestinal symptoms (ileus, nausea, vomiting, abdominal pain)

• Arrhythmias and conduction disorders, in addition to arrhythmias and conduction disorders, the ECG shows progressive changes that occur with increasing potassium levels. Possible changes include:

- peaking of T waves,

- loss of P waves, and

- QRS widening

However, the correlation between potassium levels and ECG changes is not precise, and whether or at which potassium level certain ECG signs develop depends on factors such as patient sensitivity, the presence of other electrolyte disorders, and the rapidity of the development of hyperkalaemia. The presence of any ECG findings that are suspected tobe caused by hyperkalaemia should be considered a medical emergency.

• See also section 4.4 and 4.8

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

▪ Clinically significant overdose of Potassium Chloride 0.15% w/v and Glucose 10% w/v Solution may, therefore, constitute a medical emergency.

Interventions include discontinuation of Potassium Chloride 0.15% w/v and Glucose 10% w/v Solution administration, dose reduction, administration of insulin and other measures as indicated for the specific clinical constellation.

Pharmacotherapeutic group (ATC code) : “ electrolytes with carbohydrates” (B05BB02)

Potassium Chloride 0.15 % w/v and Glucose 10 % w/v Solution for Infusion is a hypertonic solution of electrolytes and glucose, with an approximate osmolarity of 595 mOsm/l.

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

Potassium is predominantly an intracellular cation, primarily found in muscle; only about 2% is present in the extracellular fluid. It is essential for numerous metabolic and physiological processes including nerve conduction, muscle contraction, and acid-base regulation.

Chloride is mainly an extracellular anion. Intracellular chloride is in high concentration in red blood cells and gastric mucosa.

Glucose is the principal source of energy in cellular metabolism. Glucose is given as a source of carbohydrate, alone or, as required, in parenteral nutrition. The Glucose 10% w/v solution provides a caloric intake of 400 kcal/l. Furthermore glucose solution for infusion allows hydric supplementation without ionic supplementation.

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

Intravenous administration of the solution provides an immediate supply of electrolytes and glucose to blood.

Factors influencing potassium transfer between intracellular and extracellular fluid such as acid-base disturbances can distort the relationship between plasma concentrations and total body stores. Potassium is excreted mainly by the kidneys; it is secreted in the distal tubules in exchange of sodium or hydrogen ions. The capacity of the kidneys to conserve potassium is poor and some urinary excretion of potassium continues even when there is severe depletion. Some potassium is excreted in the feces and small amounts may also be excreted in sweat.

The two main metabolic pathways of glucose are gluconeogenesis (energy storage) and glycogenolysis (energy release). Glucose metabolism is regulated by insulin. Glucose is metabolised via pyruvic or lactic acid to carbon dioxide and water with release of energy.

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 if serum electrolytes are kept within physiological range.

The safety of potential additives should be considered separately.

Hydrochloric acid, concentrated

Water for Injections

As with all parenteral solutions incompatibility of the additive medications with the solution in Viaflo container must be assessed before addition.

In the absence of compatibility studies, this solution must not be mixed with other medicinal products.

It is the responsibility of the physician to judge the incompatibility of an additive medication with the Potassium Chloride 0.15 % w/v and Glucose 10 % w/v Solution for Infusion by checking for eventual color change and/or eventual precipitate, insoluble complexes or crystals apparition. The Instructions for Use of the medication to be added must be consulted.

Before adding a drug, verify it is soluble and/or stable in water at the pH of the Potassium Chloride 0.15 % w/v and Glucose 10 % w/v Solution for Infusion ( pH: 3.5 to 6.5).

When a compatible medication is added to Potassium Chloride 0.15 % w/v and Glucose 10 % w/v Solution for Infusion, the solution must be administered immediately.
