3. PHARMACEUTICAL FORM
Solution for infusion.
Clear solution, free from visible particles
Osmolarity: 295 mOsm/l (approx.) pH: approx. 7.4 (6.5 to 8.0)
4 CLINICAL PARTICULARS
4.1 Therapeutic indications
Plasma-Lyte 148 (pH 7.4) is indicated:
- for fluid replacement (e.g. after burns, head injury, fracture, infection, and peritoneal irritation),
- as intraoperative fluid replacement,
- in haemorrhagic shock and clinical conditions requiring rapid blood transfusions (compatibility with blood),
- in mild to moderate metabolic acidosis, also in case of lactate metabolism impairment.
4.2 Posology and method of administration
Adults, the Elderly, Adolescents and Children: The dosage and rate of administration depend on the age, weight, clinical and biological conditions of the patient and concomitant therapy.
The recommended dosage is:
- For adults, the elderly and adolescents: 500 ml to 3 liters / 24 h
- For infants, toddlers and children:
- 0 - 10 kg body weight: 100 ml/kg/24 h
- 10-20 kg body weight:1000 ml + (50 ml/ kg over 10 kg) / 24h
- > 20 kg body weight: 1500 ml + (20 ml/ kg over 20 kg) / 24h
Administration rate:
The infusion rate is usually 40 mL/kg/24h in adults, the elderly and adolescents.
When used for intraoperative fluid replacement, normal rate can be higher and is about 15 mL/kg/h.
In paediatric patients the infusion rate is 5 ml/kg/h in average but the value varies with age: 6-8 mL/kg/h for infants, 4-6 mL/kg/h for toddlers, and 2-4 mL/kg/h for children.
Note:
- infants and toddlers: aged from 28 days to 23 months (a toddler is an infant who can walk)
- Children: aged from 2 to 11 years.
Use in Paediatric Patients
Safety and effectiveness of Plasma-Lyte 148 (pH 7.4) in children have not been established by adequate and well controlled trials.
Use in Geriatric Patients
When selecting the type of infusion solution and the volume/rate of infusion for a geriatric patient, consider that geriatric patients are generally more likely to have cardiac, renal, hepatic, and other diseases or concomitant drug therapy.
Method of administration:
The administration is performed by intravenous route.
The solution should be administered with sterile equipment using an aseptic technique. The equipment should be primed with the solution in order to prevent air entering the system.
This solution can be administered before, during or after a blood transfusion.
Due to its iso-osmolality, this solution can be administered through a peripheral vein.
The solution 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.
Do not remove unit from overwrap until ready for use. The inner bag maintains the sterility of the solution. Administer immediately following the insertion of infusion set.
Do not use plastic containers in series connections. 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. Pressurizing intravenous solutions contained in flexible plastics 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.
Additives may be introduced before infusion or during infusion through the injection site
4.3 Contraindications
The solution is contra-indicated in patients presenting:
— Hyperchloraemia
— Hypernatraemia
— Hyperkalaemia
— Renal failure
— Heart block
— Metabolic or respiratory alkalosis
— Hypocalcaemia or hypochlorhydria
— Concomitant use with potassium-sparing diuretics (amiloride, potassium canreonate, spironolactone, triamterene) (see 4.5)
— Hypersensitivity to the active substances or to any of the excipients listed in s section 6.1
4.4 Special warnings and precautions for use
WARNINGS Electrolyte balance
Plasma-Lyte 148 (pH 7.4) is not indicated for the treatment of hypochloraemic hypokalaemic alkalosis.
Plasma-Lyte 148 (pH 7.4) is not indicated for the primary treatment of severe metabolic acidosis neither for the treatment of hypomagnesaemia.
Use in Patients with or at Risk for and from Hypermagnaesemia Parenteral magnesium salts should be used with caution in less severe degrees of renal impairment and in patients with myasthenia gravis. Patients should be monitored for clinical signs of excess magnesium, particularly when being treated for eclampsia. (See also section 4.5 - Interactions with other Medicinal Products and other forms of interaction)
Use in patients with Hypocalcaemia
Plasma-Lyte 148 (pH 7.4) contains no calcium, and an increase in plasma pH due to its alkalinizing effect may lower the concentration of ionized (not protein-bound) calcium. Plasma-Lyte 148 (pH 7.4) should be administered with particular caution to patients with hypocalcaemia.
Use in Patients with or at Risk for Hyperkalaemia
Solutions containing potassium salts should be administered with caution 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. The plasma potassium level of the patient should be particularly closely monitored in patients at risk of hyperkalaemia.
The following combinations are not recommended; they increase the concentration of potassium in the plasma and may lead to potentially fatal hyperkalaemia notably in case of renal failure increasing the hyperkalaemic effects (see 4.5).
- Angiotensin converting enzyme inhibitors (ACEi) and, by extrapolation, angiotensin
II receptor antagonists : hyperkalaemia potentially lethal
- Tacrolimus, cyclosporin
Use in _patients with _potassium deficiency
Although Plasma-Lyte 148 (pH 7.4) solution has a potassium concentration similar to the concentration in plasma, it is insufficient to produce a useful effect in case of severe potassium deficiency and therefore it should not be used for this purpose.
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 Plasma-Lyte 148 (pH 7.4) can cause
- fluid and/or solute overload resulting in overhydration/hypervolaemia 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
Plasma-Lyte 148 (pH 7.4) 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 edema, impaired renal function, pre-eclampsia, aldosteronism, or other conditions associated with sodium retention (see also Section 4.5 - Interactions with other Medicinal Products and forms of interaction).
Use in Patients with Severe Renal Impairment
Plasma-Lyte 148 (pH 7.4) should be administered with particular caution to patients with severe renal impairment. In such patients administration of Plasma-Lyte 148 (pH
7.4) may result in sodium and/or potassium or magnesium retention.
Acid-base balance
Use in Patients with or at Risk_ for Alkalosis
Plasma-Lyte 148 (pH 7.4) should be administered with particular caution to patients with alkalosis or at risk for alkalosis. Excess administration of Plasma-Lyte 148 (pH
7.4) can result in metabolic alkalosis because of the presence of acetate and gluconate ions.
Other warnings
Hypersensitivity Reactions
Hypersensitivity/infusion reactions, including anaphylactoid reactions, have been reported with Plasma-Lyte 148 (pH 7.4)
The infusion must be stopped immediately if any signs or symptoms of a suspected hypersensitivity reaction develop. Appropriate therapeutic countermeasures must be instituted as clinically indicated.
Administration
Administration in the postoperative period shortly after recovery from neuromuscular block should be used with caution since magnesium salts can lead to recurarisation effect.
When used concomitantly with parenteral nutrition, electrolyte supply should be taken into account and adjusted accordingly.
PRECAUTIONS
Interference with laboratory tests for gluconate containing solutions There have been reports of false-positive test results using the Bio-Rad Laboratories Platelia Aspergillus EIA test in patients receiving Baxter gluconate containing Plasmalyte solutions. These patients were subsequently found to be free of Aspergillus infection. Therefore, positive test results for this test in patients receiving Baxter gluconate containing Plasmalyte solutions should be interpreted cautiously and confirmed by other diagnostic methods.
Administration
Adding other medications or using an incorrect administration technique might cause the appearance of fever reactions due to the possible introduction of pyrogens. In case of an adverse reaction, infusion must be stopped immediately.
For information on incompatibilities and preparation of the product and additives, please see section 6.2 and 6.6.
4.5 Interaction with other medicinal products and other forms of interaction
Interaction related to the presence of sodium:
- Corticoids/Steroids and carbenoxolone, which are associated with the retention of sodium and water (with oedema and hypertension).
Interaction related to the presence of potassium:
The following combinations increase the concentration of potassium in the plasma and may lead to potentially fatal hyperkalaemia notably in case of renal failure increasing the hyperkalaemic effects:
Contra-indicated combination
- Potassium-sparing diuretics (amiloride, potassium canreonate, spironolactone, triamterene, alone or in combination ) (see 4.3),
Combination not recommended
- Angiotensin converting enzyme inhibitors (ACEi) and, by extrapolation, angiotensin II receptor antagonists: hyperkalaemia potentially lethal (see 4.4),
- Tacrolimus, cyclosporin (see 4.4)
Administration of potassium in patients treated with such medications can produce severe and potentially fatal hyperkalaemia, particularly in patients with severe renal insufficiency.
Interaction related to the presence of magnesium:
- Neuromuscular blockers such as tubocurarine, suxamethonium, and vecuronium whose effects are enhanced by the presence of magnesium.
- Acetylcholine whose release and effects are reduced by magnesium salts what may contribute to neuromuscular blockade.
- Aminoglycoside antibacterials and nifedipine that have additive effects with parenteral magnesium and enhanced the neuromuscular blocking.
Interaction related to the presence of acetate and gluconate (which are metabolised into bicarbonate):
Caution is advised when administering Plasma-Lyte 148 (pH 7.4) to patients treated with drugs for which renal elimination is pH dependent. Due to its alkalinizing effect (formation of bicarbonate), Plasma-Lyte 148 (pH 7.4) may interfere with the elimination of such drugs.
- Renal clearance of acidic drugs such as salicylates, barbiturates and lithium may be increased because of the alkalinisation of urine by the bicarbonate resulting from acetate and gluconate metabolism.
- Renal clearance of alkaline drugs such as sympathomimetics (e.g. ephedrine, pseudoephedrine) and stimulants (e.g. dexamphetamine sulphate, phenfluramine hydrochloride) may be decreased.
4.6 Fertility, pregnancy and lactation
There are no adequate data from the use of Plasma-Lyte 148 (pH 7.4) solution for infusion in pregnant or lactating women. The potential risks and benefits for each specific patient should be carefully considered before using Plasma-Lyte 148 (pH 7.4) solution for infusion in pregnancy or lactating woman.

4.9. Overdose
Overuse or too fast administration may lead to water and sodium overload with a risk of oedema, particularly when there is a defective renal sodium excretion. In this case extra renal dialysis may be necessary.
Excessive administration of potassium may lead to the development of hyperkalaemia, 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 hyperkalaemia involves the administration of calcium, insulin (with glucose) sodium bicarbonate, exchange resins or dialysis.
Excessive parenteral administration of magnesium salts leads to the developments of hypermagnesaemia, important signs of which are loss of deep tendon reflexes and respiratory depression, both due to neuromuscular blockade. Other symptoms of hypermagnesaemia may include nausea, vomiting, flushing of the skin, thirst, hypotension due to peripheral vasodilatation, drowsiness, confusion, muscle weakness, bradycardia, coma, and cardiac arrest. A patient with supralethal hypermagnesaemia was successfully treated using assisted ventilation, calcium chloride, administered intravenously, and forced diuresis with mannitol infusions.
Excessive administration of chloride salts may cause a loss of bicarbonate with an acidifying effect.
Excessive administration of compounds, such as sodium acetate and sodium gluconate, which are metabolised to form the bicarbonate anion may lead to hypokalaemia 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 hypocalcaemic patients.
Treatment of metabolic alkalosis associated with bicarbonate overdose consists mainly of appropriate correction of fluid and electrolyte balance.
When overdose is related to medications added to the solution infused, the signs and symptoms of over infusion will be related to the nature of the additive being used. In the event of accidental over infusion, treatment should be discontinued and the patient should be observed for the appropriate signs and symptoms related to the drug administered. The relevant symptomatic and supportive measures should be provided as necessary.
