- Instruction Clinical Particulars
- 4.1 Therapeutic indications
Potassium Chloride 0.15 % w/v & Sodium Chloride 0.9% w/v Solution for Infusion is indicated for the prevention and treatment of potassium depletion and/or hypokalaemia, in sodium chloride and water-losing conditions.4.2 Posology and method of administration
Posology
Adults, the Elderly\*\*\*,\*\*\* Adolescents and Children
Fluid balance, serum electrolytes and acid-base balance should be monitored before and during administration, with particular attention to serum sodium 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 hospital acquired hyponatraemia (see sections 4.4, 4.5 and 4.8). Monitoring of serum sodium is particularly important for hypotonic fluids.
Potassium Chloride 0.15% & Sodium Chloride 0.9% Solution for Infusion has a tonicity of 348 mOsm/l (approx.)
The infusion rate and volume depend on the age, weight, clinical condition (e.g. burns, surgery, head-injury, infections), and concomitant therapy should be determined by the consulting physician experienced in paediatric intravenous fluid therapy (see sections 4.4. and 4.8).
Doses may be expressed in terms of mEq or mmol of each cation, mass of each cation, or mass of each cation salt:
- for sodium
1 g NaCl = 394 mg of Na+ or 17.1 mEq or 17.1 mmol of Na+ and Cl-
1 mmol Na+ = 23mg Na+
- for potassium
1 g KCl = 525 mg of K+ or 13.4 mEq or 13.4 mmol of K+ and Cl-
1 mmol K+ = 39.1 mg K+
\*Posology for prevention and treatment of potassium depletion\*
- For Adults, the Elderly and Adolescents:
Typical dose of potassium for the prevention of hypokalaemia may be up to 50 mmoles daily and similar doses may be adequate in mild potassium deficiency.
When used for treatment of hypokalaemia, the recommended dosage is 20 mmoles of potassium over 2 to 3 hours (i.e. 7-10 mmol/h) under ECG control.
The maximum recommended administration rate should not exceed 15-20 mmol/h.
Patient with renal impairment should receive lower doses.
- Use in Paediatric Population (28 days to 11 years):
The maximal recommended dose of potassium is 2 to 3 mmol/kg bw/day.
\*Method of Administration\*
The administration is performed by intravenous route using sterile and non-pyrogenic equipment.
Intravenous potassium should be administered in 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.
The osmolarity of a final admixed infusion solution must be taken into account when peripheral administration is considered.
Hyperosmolar solutions may cause venous irritation and phlebitis. Thus, clinically significant hyperosmolar solutions are recommended to be administered through a large central vein, for rapid dilution of the hyperosmolar solution.
Additional electrolyte supplementation may be indicated according to the clinical needs of the patient. When introducing additives to Potassium chloride 0.15% w/v & Sodium Chloride 0.9% w/v solution for infusion, the instructions for use of the medication to be added and other relevant literature must be consulted (see also \*Special precautions for disposal and other handling, section 6.6\*).
\*Risk of air embolism\*
Do not connect flexible plastic containers in series in order to avoid air embolism due to possible residual air contained in the primary container.
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.
\*Rate of administration\*
Solution containing potassium should be administered slowly. As administered intravenously, potassium should not be given faster than 15 to 20 mmoles/h to avoid a dangerous hyperkalaemia. Rapid correction of hyponatremia and hypernatremia is potentially dangerous (risk of serious neurological complications) (see also Special Warnings and precautions for Use; section 4.4).
\*Monitoring\*
Adequate urine flow must be ensured and careful monitoring of plasma-potassium and other electrolyte concentrations is essential. High dosage or high speed infusion must be performed under ECG control.4.3 Contraindications
The Potassium chloride 0.15 % w/v & Sodium Chloride 0.9% w/v solution for infusion is contra-indicated in patients with:
- known hypersensitivity to the product
- documented hyperkalaemia, hyperchloraemia or hypernatraemia

- uncompensated cardiac failure
- Addison's disease4.4 Special warnings and precautions for use
Potassium chloride 0.15% w/v & Sodium chloride 0.9% w/v Solution for Infusion is a hypertonic solution.
\*Hypersensitivity reactions:\*
- Hypersensitivity/infusion reactions, including anaphylaxis, have been reported with other products containing potassium chloride and sodium chloride.
- Stop the infusion immediately if signs or symptoms of hypersensitivity/infusion reactions develop. Appropriate therapeutic countermeasures must be instituted as clinically indicated.
\*Risk of serum electrolytes and water imbalance\*
Depending on the volume and rate of infusion and depending on a patient's underlying clinical condition, intravenous administration of Potassium Chloride 0.15% w/v & Sodium Chloride 0.9% w/v Solution for infusion can cause:
 electrolyte disturbances such as
- Hypernatremia,
- Hyponatremia (see use in patients at risk for sodium imbalance).
 acid−base imbalance.
 overhydration/hypervolemia and, for example, congested states, including central (e.g., pulmonary congestion) and peripheral edema.
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.
High volume infusion must be used under specific monitoring in patients with cardiac or pulmonary failure and in patients with non-osmotic vasopressin release (including SIADH), due to the risk of hospital-acquired hyponatraemia (see below).
\*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 (cerebral oedema) characterized by headache, nausea, seizures, lethargy and vomiting. Patients with cerebral 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, cerebral contusion and brain oedema) are at particular risk of the severe and life-threatening brain swelling caused by acute hyponatraemia.
Potassium salts should be administered with considerable care to patients with cardiac disease or conditions predisposing to hyperkalaemia such as renal or adrenocortical insufficiency, acute dehydration, or extensive tissue destruction as occurs with severe burns. In patients under digitalis therapy, regular monitoring of the plasma potassium level is mandatory.
Sodium salts should be administered with caution to patients with hypertension, heart failure, peripheral or pulmonary oedema, impaired renal function, pre-eclampsia, or other conditions associated with sodium retention (see also Section 4.5 − Interactions with other medicinal products and other forms of interaction).
\*Pediatric 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 pediatric 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 and/or concomitant drug therapy.4.5 Interaction with other medicinal products and other forms of interaction
Caution is advised in patients treated with lithium. Renal sodium and lithium clearance may be increased during administration of Potassium Chloride 0.15 %w/v & Sodium chloride 0.9% w/v Solution for infusion and this can result in decreased lithium levels.
Potassium Chloride 0.15 %w/v & Sodium chloride 0.9% w/v Solution for infusion should be used with caution in patients treated concurrently or recently with agents or products that can cause hyperkalemia or increase the risk of hyperkalemia, such as medicinal products that contains potassium, potassium sparing diuretics, ACE inhibitors, angiotensin II receptor antagonists, or the immunosuppressants cyclosporine and tacrolimus.
Administration of potassium in patients treated with such agents is associated with an increased risk of severe and potentially fatal hyperkalemia, in particular in the presence of other risk factors for hyperkalemia.
Potassium Chloride 0.15 %w/v & Sodium chloride 0.9% w/v Solution for infusion should be used with particular caution in patients on concomitant medications that may increase the risk of sodium and fluid retention, such as corticosteroids.
\*Drugs leading to an increased vasopressin effect\*
The below listed drugs increase the vasopressin effect, leading to reduced renal electrolyte free water excretion and may 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 include: Chlorpropamide, clofibrate, carbamazepine, vincristine, selective serotonin reuptake inhibitors, 3.4-methylenedioxy-N-methamphetamine, ifosfamide, antipsychotics, narcotics
▪ Drugs potentiating vasopressin action include: Chlorpropamide, NSAIDs, cyclophosphamide
▪ Vasopressin analogues include: Desmopressin, oxytocin, terlipressin

- Instruction Pharmacology
- 5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Electrolytes
ATC code: B05BB01
Potassium Chloride 0.15% w/v & Sodium Chloride 0.9% w/v Solution for Infusion is an hypertonic solution of electrolytes, with an approximate osmolarity of 348 mOsm/l.
The pharmacodynamic properties of the solution are those of the sodium, potassium and chloride ions in maintaining the fluid and electrolyte balance.
Potassium is essential for numerous metabolic and physiological processes including nerve conduction, muscle contraction, and acid-base regulation. A normal concentration of potassium in plasma is about 3.5 to 5.0 mmoles per liter. Potassium is predominantly an intracellular cation. The passage of potassium into the cells and retention against the concentration gradient requires active transport via the Na+/K+ ATPase enzyme.
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. Reabsorption of chloride follows reabsorption of sodium.5.2 Pharmacokinetic properties
The pharmacokinetic properties of Potassium Chloride 0.15% w/v & Sodium Chloride 0.9% w/v Solution for Infusion are those of the ions its composition includes (sodium, potassium and chloride).
Intravenous administration of the solution provides an immediate supply of electrolytes 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.
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 neurons; it is very slow in the bone. Sodium is predominantly excreted by the kidney, but there is extensive renal reabsorption. Small amounts of sodium are lost in the feces and sweat.5.3 Preclinical safety data
Preclinical safety data of Potassium Chloride 0.15% w/v & Sodium Chloride 0.9% w/v Solution for Infusion in animals are not relevant since electrolytes are physiological components of the body.

## Pharmacological Properties
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Electrolytes
ATC code: B05BB01
Potassium Chloride 0.15% w/v & Sodium Chloride 0.9% w/v Solution for Infusion is an hypertonic solution of electrolytes, with an approximate osmolarity of 348 mOsm/l.
The pharmacodynamic properties of the solution are those of the sodium, potassium and chloride ions in maintaining the fluid and electrolyte balance.
Potassium is essential for numerous metabolic and physiological processes including nerve conduction, muscle contraction, and acid-base regulation. A normal concentration of potassium in plasma is about 3.5 to 5.0 mmoles per liter. Potassium is predominantly an intracellular cation. The passage of potassium into the cells and retention against the concentration gradient requires active transport via the Na+/K+ ATPase enzyme.
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. Reabsorption of chloride follows reabsorption of sodium.5.2 Pharmacokinetic properties
The pharmacokinetic properties of Potassium Chloride 0.15% w/v & Sodium Chloride 0.9% w/v Solution for Infusion are those of the ions its composition includes (sodium, potassium and chloride).
Intravenous administration of the solution provides an immediate supply of electrolytes 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.
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 neurons; it is very slow in the bone. Sodium is predominantly excreted by the kidney, but there is extensive renal reabsorption. Small amounts of sodium are lost in the feces and sweat.5.3 Preclinical safety data
Preclinical safety data of Potassium Chloride 0.15% w/v & Sodium Chloride 0.9% w/v Solution for Infusion in animals are not relevant since electrolytes are physiological components of the body.
