2 QUALITATIVE AND QUANTITATIVE COMPOSITION

Potassium Chloride 0.3% and Glucose 5% Solution for Infusion has the following composition:

For a full list of excipients, see 6.1.

3 PHARMACEUTICAL FORM

Solution for Infusion.

4 CLINICAL PARTICULARS.

4.1 Therapeutic indications

Potassium replacement therapy.

4.2 Posology and method of administration

Fluid balance, serum glucose, serum sodium and other electrolytes may need to 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 0.3% and Glucose 5% Solution for Infusion may become extremely hypotonic after administration due to glucose metabolization in the body (see sections 4.4, 4.5 and 4.8).

The volume and rate of infusion will depend upon the requirements of the individual patient and the judgement of the physician.

Adults

The rate of infusion should not exceed 10-20 mmols of potassium per hour. The total daily dosage of potassium should not exceed 200 mmols of potassium.

Children

Correspondingly reduced volumes and rates of infusion may be required.

Elderly

A reduced volume and rate of infusion may be necessary to avoid circulatory overload, particularly in patients with cardiac or renal insufficiency.

Method of Administration

For Solution for Infusion.

4.3 Contraindications

Addison's disease, adrenal insufficiency, acute or chronic renal disease, oliguria, anuria and patients with hyperkalaemia.

Potassium Chloride and Glucose Solutions for Infusion may also be hazardous in patients with impaired hepatic function.

4.4 Special warnings and precautions for use

Glucose solution for 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 Solution for Infusion

administration of glucose can cause electrolyte disturbances most importantly hypo- or hyperosmotic hyponatraemia.

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.

Intravenous infusion must be carried out slowly. Caution should be used with administration to patients receiving digitalis therapy, patients with renal or adrenal insufficiency, cardiac disease, acute dehydration or heat cramp, those receiving potassium sparing diuretics and patients with sickle cell haemoglobinopathy.

Caution should be exercised in the volume and rate of infusion since fluid overload and hyperkalaemia may compromise cardiac function. Before administering potassium by the intravenous route a non-potassium containing hydrating solution should be administered to ensure adequate renal function.

The label states:

Do not use unless the solution is clear and free from particles. Rapid infusion may be harmful.

Contains 20 mmol Potassium (500 ml)

Contains 40 mmol Potassium (1000 ml)

4.5 Interaction with other medicinal products and other forms of interaction

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 solution for infusions (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, vasopressin, terlipressin.

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

Care should be exercised in the concurrent administration of potassium containing intravenous solutions and potassium sparing diuretics.

ACE-inhibitors; Cyclosporin; care should be taken when administering to patients with digitalis therapy.

4.6 Fertility, pregnancy and lactation

Potassium Chloride 0.3% and Glucose 5% Solution for Infusion 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).

The safety of potassium containing solutions during pregnancy and lactation has not been assessed, but its use during these periods is not considered to constitute a hazard.

4.7 Effects on ability to drive and use machines.

Not Applicable.

4.8 Undesirable effects

Adverse effects are usually due to hyperkalaemia and include listlessness, mental confusion, parasthesiae, weakness, hypertension, arrhythmias and sometimes cardiac arrest.

Thrombosis of the selected vein may occasionally occur.

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

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 or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose

Symptoms of overdosage including hypotension, cardiac arrhythmias, heart block and cardiac arrest. Treatment is to stop infusion immediately and if there is persistent acidosis, administer an intravenous infusion of sodium bicarbonate. Hyperkalaemia may be reversed by the administration of calcium gluconate injection 10% with ECG monitoring.

5 PHARMACOLOGICAL PROPERTIES

5.1 Pharmacodynamic properties

Potassium chloride provides essential ions to maintain the intracellular/extracellular milieu.

Glucose is a monosaccharide which provides a source of energy.

5.2 Pharmacokinetic properties

Glucose is metabolised via pyruvic or lactic acid to carbon dioxide and water with the release of energy. All body cells are capable of oxidising glucose and it forms the principal source of energy in cellular metabolism.

5.3 Preclinical safety data

None Stated.

Opening the overwrap:

Locate the corner tabs at the end of the bag. Grip the two tabs and pull the two halves of the overwrap apart, releasing the bag onto a clean surface.

Setting up the solution:

Position the roller clamp of the giving-set to just below the drip chamber and close. Hold the base of the giving set port firmly and grip the wings of the twist of tab. Twist to remove the protective cover. Still holding the base of the giving-set port push the set spike fully into the port to ensure a leak proof connection. Prime the set in accordance with the manufacturer’s instructions.
