3 PHARMACEUTICAL FORM
Solution for infusion (Intravenous Infusion)
Colourless to faintly straw-coloured solution without visible particles in bags, individually
overwrapped.
pH 3.5 - 6.5
4 CLINICAL PARTICULARS
4.1 Therapeutic indications
For correction and maintenance of fluid, potassium, sodium and chloride ion balance and as a source of energy, where oral administration is not feasible.
4.2 Posology and method of administration
For intravenous infusion under medical supervision.
The volume of solution needed to replenish deficits varies with hydration state, age, body weight, complementary treatment and clinical and biochemical status.
Doses may be expressed in terms of mEq or mmol of potassium, mass of potassium or mass of potassium salt:
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
- Adults:
500ml to 3000ml/24h
- Paediatric population:
0 - 10kg body weight: 100ml/kg/24h
10 - 20kg body weight: 1000ml + (50ml/kg over 10kg)/24h
> 20kg body weight: 1500ml + (20ml/kg over 20kg)/24h
The infusion rate should not exceed the patient’s glucose oxidation capacities in order to avoid hyperglycaemia. Therefore the maximum dose ranges from 5mg/kg/min for adults to 10-18 mg/kg/min for babies and children depending on age and total body mass.
Posology for prevention and treatment ofpotassium depletion Typical doses of potassium for the prevention of hypokalaemia and treatment of mild potassium deficiency may be up to 50mmoles per day. In severe hypokalaemia the recommended dosage is 20mmol potassium over 2 to 3 hours (i.e. 7-10 mmol/h) with ECG monitoring, but the dose and rate of administration are subject to clinical and laboratory assessment in each case.
The recommended maximal dose of potassium is 2-3mmol/kg/24h.
Patients with renal impairment should receive lower doses.
Method of Administration Route 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 a central vein, to avoid localized hyperkalaemia the catheter must not be in the atrium or ventricle.
Rate of administration
The rate of administration of potassium containing solutions should not exceed 15 to 20 mmoles/h to avoid dangerous hyperkalaemia. Rapid infusion may be harmful.
Monitoring
Adequate urine flow must be ensured and careful monitoring of plasma-potassium and other electrolyte concentrations is essential. Higher dosage or high speed infusion must be performed under ECG control.
4.3 Contraindications
Hyperkalaemia such as is associated with severe renal insufficiency or adrenocortical insufficiency.
Hyperchloraemia. uncompensated cardiac failure, uncompensated diabetes, other known glucose intolerances (such as metabolic stress situations, thionine (Vit B1) deficiency), hyperosmolar coma, hyperglycaemia, hyperlactatemia. Acute ischaemic stroke, head trauma (first 24 hours). Patients with fluid and sodium retention, congestive heart failure, or severely impaired renal function.
4.4 Special warnings and precautions for use
Potassium Chloride 0.3%w/v Sodium Chloride 0.18%w/v Glucose 4%w/v Solution for Infusionis a hypertonic solution, with an approximate osmolarity of 366mOsm/l.
Potassium replacement must be used with caution to patients with conditions associated with high potassium levels including cardiac disease oedema, renal dysfunction, hepatic insufficiency or digitilisation, acute dehydration, acute acidosis, extensive tissue destruction as occurs with tissue trauma and severe burns, haemolysis, rhabdomyolysis or hepatic insufficiency.
Sodium salts should be administered with caution to patients with hypertension.
Use with caution in patients with diabetes mellitus; insulin requirements may be modified.
Solutions containing glucose should not be used for initial treatment of potassium depletion because glucose may cause a further decrease in plasma potassium concentration.
Glucose infusions are incompatible with blood for transfusion as haemolysis or clumping can occur; do not administer through the same infusion equipment as blood or blood components for transfusion (either before, during or after their administration).
Fluid replacement therapy should be administered with caution to very young and elderly patients who have reduced capacity to compensate for fluctuations in fluid and electrolyte balance.
Administration should be carried out under regular and careful surveillance. Regular monitoring of clinical status, plasma potassium, blood and urinary glucose level, serum and/or urinary electrolytes, plasma creatinine levels, BUN level, acid-base balance and ECG is essential in patients receiving potassium therapy, particularly those with cardiac or renal impairment. Plasma electrolyte concentrations should be carefully monitored especially in patients with pre-existing imbalances or conditions predisposing to hyperkalaemia, such as renal or adrenal insufficiency.
High volume infusion must be used under specific monitoring in patients with cardiac or pulmonary failure.
Adequate urine flow must be ensured and fluid balance should be monitored.
Blood glucose concentration should be closely monitored during intracranial hypertension episodes.
If hyperglycaemia occurs, the rate of infusion should be adjusted or insulin administered.
During long-term treatment, a convenient nutritive treatment supply must be given to the patient.
4.5 Interaction with other medicinal products and other forms of interaction
Care should be taken in the concurrent use of drugs containing potassium, potassiumsparing diuretics, such as spironolactone and triamterene, and drugs which have the potential for inducing hyperkalaemia, ACE (angiotensin converting enzyme) inhibitors, angiotensin II receptor antagonists, tacrolimus and cyclosporine, as well as drugs which promote sodium retention such as corticosteroids.
Check compatibility of medicinal products with the solution before use.
4.6 Fertility, pregnancy and lactation
Administration of intravenous fluids to pregnant and lactating women requires consideration of the consequences of possible unwanted effects in relation to the desired therapeutic objective.
Sodium salts should be administered with caution to patients with pre-eclampsia.
It has been suggested that if used during labour the glucose load on the mother may lead to foetal hyperglycaemia, hyperinsulinaemia, and acidosis, with subsequent neonatal hypoglycaemia and jaundice. Others have found no evidence of such an effect.
Hyperkalaemic and hypokalaemic serum levels lead to impaired cardiac function of the maternal and foetal hearts. Therefore, maternal electrolyte levels must be controlled regularly. As long as the maternal electrolyte serum levels are kept within the physiological range, there are no potential concerns regarding administration of Potassium Chloride 0.3%w/v Sodium Chloride 0.18%w/v Glucose 4%w/v Solution for Infusion during pregnancy and lactation.
4.7 Effects on ability to drive and use machines
Not applicable
4.8 Undesirable effects

4.9 Overdose
Prolonged or rapid intravenous infusion may lead to venous irritation and thrombophlebitis at the infusion site.
Excessive or rapid administration of potassium-containing solutions may cause hyperkalaemia with hypotension, cardiac arrhythmias, heart block, ECG abnormalities and cardiac arrest, mental confusion, and neuromuscular dysfunction such as muscle weakness, paraesthesia and paralysis.
ECG changes are important indicators of potassium toxicity, including tall, peaked T-waves, depression of S-T segment, disappearance of the P-wave, prolongation of the Q-T interval, and widening and slurring of the QRS complex.
Excessive or rapid administration of sodium chloride solution may lead to fluid and electrolyte imbalances such as hypervolaemic haemodilution, also hypertension, tachycardia, and oedema. Excessive administration of chloride salts may cause a loss of bicarbonate with an acidifying effect.
In the event of accidental over infusion, treatment should be discontinued.
Treatment depends on the individual clinical situation but involves administration of calcium to counteract the effects of hyperkalaemia on cardiac excitability, the use of agents such as insulin or sodium bicarbonate to promote cellular uptake of potassium, and enhanced potassium excretion with exchange resins or dialysis. Administration of excessive amounts of 4% glucose may result in hyperglycaemia. Treatment is symptomatic.
Discontinue infusion if adverse reaction occurs.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group (ATC code): “electrolytes with carbohydrates” (B05BB02).
Potassium Chloride 0.3%w/v Sodium Chloride 0.18%w/v Glucose 4%w/v Solution for Infusion is a hypertonic solution, with an approximate osmolarity of 366 mOsmol/l.
The pharmacodynamic properties of this solution are those of its components (potassium, sodium, 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.
Sodium is mainly an extracellular cation. 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.
5.2 Pharmacokinetic properties
The pharmacokinetic properties of this solution are those of its components (potassium, sodium, 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 for 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 faeces 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.
5.3 Preclinical safety data
Preclinical safety data of Potassium Chloride 0.3%w/v Sodium Chloride 0.18%w/v
Glucose 4%w/v Solution for Infusion in animals are not relevant since potassium chloride, sodium chloride and glucose are physiological components of the body. Toxic effects are not to be expected if serum electrolytes are kept within physiological range.
