- Instruction Dosage Form
- Solution for infusion.
A clear, colourless solution.
Primene 10% has a pH of 5.5 and an osmolarity of 780 mOsmol/L.
- Instruction Clinical Particulars
- 4.1 Therapeutic indications
Primene 10% is indicated in 1) children and infants 2) neonates, at term or premature, of normal or low birth weight when oral or enteral nutrition is impossible, insufficient or contraindicated.4.2 Posology and method of administration
\*\*Posology\*\*
Parenteral nutrition initiation and duration as well as dosage (dose and rate of administration) depends on a patient's
• age, weight, clinical condition,
• nitrogen requirements,
• ability to metabolize the constituents of Primene,
• additional nutrition that may be provided parenterally and/or enterally.
The usual range is
1.5 – 3.5g amino-acids/kg/24 hours
0.230 – 0.53g nitrogen/kg/24 hours15 – 35ml of Primene 10%/kg/24 hours
The infusion rate should not exceed 0.05ml/kg/min.
Recommended flow rates:
Neonates and Infants: continuous infusion (over 24 hours).Children: continuous infusion (over 24 hours) or cyclic infusion (over about 12 hours in 24).
The flow rate should be adjusted according to the dosage, the characteristics of the infusion solution, the total volume intake per 24 hours and the infusion duration.
The flow rate should be increased gradually during the first hour.
\*\*Method of administration\*\*
Primene is intended for intravenous use.
Primene is not intended for fluid or volume replacement.
When used in neonates and children below 2 years of age, the solution (in bottles and administration sets) should be protected from light exposure until administration is completed (see sections 4.4, 6.3 and 6.6).
Primene 10% is usually administered with a source of energy appropriate for the needs of the child, either by co-administration or as a mixture.
Primene 10% may be included in the composition of nutritive mixtures combining carbohydrates, lipids, electrolytes, trace elements and vitamins to meet nutrient needs and prevent deficiencies and complications from developing, when compatibility and stability are known (see section 6.2).
Primene 10% alone should be administered in a central vein.
Primene 10% in co-administration or as a mixture should be administered according to the final osmolarity of the solution infused, in a peripheral or central vein.
The osmolarity of a specific infusion solution must be taken into account when peripheral administration is considered.
Strongly hypertonic parenteral nutrition solutions (>900 mOsm/L) should be administered through a central venous catheter with the tip located in a large central vein.
If deemed appropriate by the healthcare professional, parenteral nutrition solution may be administered peripherally in patients of all ages if the osmolarity of the formulation is ≤ 900 mOsm/L.4.3 Contraindications
Primene is contraindicated in patients with:
• hypersensitivity to any of the active substances or to any of the excipients listed in section 6.1.
• congenital abnormality of amino acid metabolism.4.4 Special warnings and precautions for use
\*Allergic Reactions / Hypersensitivity Reactions\*
Anaphylactic/anaphylactoid reactions and other hypersensitivity/infusion reactions have been reported with amino acid solutions administered as a component of parenteral nutrition (see section 4.8). The infusion must be stopped immediately if any signs or symptoms of a reaction develop.
\*Precipitates in Patients Receiving Parenteral Nutrition\*
Pulmonary vascular precipitates have been reported in patients receiving parenteral nutrition. In some cases, fatal outcomes have occurred. Excessive addition of calcium and phosphate increases the risk of the formation of calcium phosphate precipitates. Precipitates have been reported even in the absence of phosphate salt in the solution. Precipitation distal to the in-line filter and suspected in vivo precipitate formation has also been reported.
If signs of pulmonary distress occur, the infusion should be stopped and medical evaluation initiated.
In addition to inspection of the solution, the infusion set and catheter should also periodically be checked for precipitates.
\*Infectious complications\*
Infection and sepsis may occur as a result of intravenous catheters used to administer parenteral formulations, poor maintenance of catheters or contaminated solutions.
Immunosuppression and other factors such as hyperglycaemia, malnutrition and/or their underlying disease state may predispose patients to infectious complications.
Careful symptomatic and laboratory monitoring for fever/chills, leukocytosis, technical complications with the access device, and hyperglycaemia can help recognize early infections.
The occurrence of septic complications can be decreased with heightened emphasis on aseptic technique in catheter placement, maintenance, as well as aseptic technique in nutritional formula preparation.
\*Refeeding Syndrome in Patients Receiving Parenteral Nutrition\*
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 intakes while avoiding overfeeding can prevent these complications.
\*Hypertonic solutions\*
Hypertonic infusion solutions may cause irritation of the vein, vein damage, and thrombosis when administered into a peripheral vein (see section 4.8).
In view of its osmolality, Primene 10% should not be infused alone into a peripheral vein.
\*General Monitoring\*
Monitoring should be appropriate to the patient's clinical situation and condition, and should include determinations of water and electrolyte balance, serum osmolarity, acid/base balance, blood glucose levels, blood ammonia levels, and liver and kidney function.
\*Metabolic Effects\*
Metabolic complications may occur if the nutrient intake is not adapted to the patient's requirements, or the metabolic capacity of any given dietary component is not accurately assessed. Adverse metabolic effects may arise from administration of inadequate or excessive nutrients or from inappropriate composition of an admixture for a particular patient's needs.
\*Hepatic function\*
Patients on parenteral nutrition may experience hepatic complications (including cholestasis, hepatic steatosis, fibrosis and cirrhosis, possibly leading to hepatic failure, as well as cholecystitis and cholelithiasis) and should be monitored accordingly. The etiology of these disorders is thought to be multifactorial and may differ between patients. Patients developing abnormal laboratory parameters or other signs of hepatobiliary disorders should be assessed by a clinician knowledgeable in liver diseases in order to identify possible causative and contributory factors, and possible therapeutic and prophylactic interventions.
Amino acid solutions should be used with caution in patients with pre-existing liver disease or liver insufficiency.
Liver function parameters should be closely monitored in these patients, and they should be monitored for possible symptoms of hyperammonaemia.
Increase in blood ammonia levels and hyperammonaemia may occur in patients receiving amino acid solutions. In some patients this may indicate the presence of a congenital disorder of amino acid metabolism (see section 4.3) or hepatic insufficiency.
Blood ammonia should be measured frequently in newborns and infants to detect hyperammonaemia.
Depending on extent and etiology, hyperammonaemia may require immediate intervention.
\*Renal effects\*
Azotaemia has been reported with parenteral administration of solutions containing amino acids, and may occur in particular in the presence of renal impairment.
Use with caution in patients with renal insufficiency (with e.g., uraemia). Nitrogen tolerance may be altered and dosage may have to be adjusted. Fluid and electrolyte status should be closely monitored in these patients.
\*Additional precautions\*
• Light exposure of solutions for intravenous parenteral nutrition, especially after admixture with trace elements and/or vitamins, may have adverse effects on clinical outcomes in neonates, due to the generation of peroxides and other degradation products. When used in neonates and children below 2 years of age, Primene should be protected from ambient light until administration is completed (see sections 4.2, 6.3, and 6.6).
• Infusion site reactions have occurred with the use of parenteral nutrition. They include infusion site thrombophlebitis and venous irritation, as well as severe reactions (with, e.g., necrosis and blistering) when associated with extravasation. See section 4.8. Patients should be monitored accordingly.
• Severe water and electrolyte disorders, severe fluid overload states, and severe metabolic disorders should be corrected before starting the infusion.
• Use with caution in patients with pulmonary oedema or heart failure. Fluid status should be closely monitored.4.5 Interaction with other medicinal products and other forms of interaction
No interaction studies have been performed.
The compatibility and stability of nutritive mixtures should be confirmed before administration.4.6 Fertility, pregnancy and lactation
There are no adequate data from the use of Primene in pregnant or lactating women. Healthcare Professionals should carefully consider the potential risks and benefits for each specific patient before administering Primene.4.7 Effects on ability to drive and use machines
There is no information of the effects of Primene on the ability to drive or operate other heavy machinery.4.8 Undesirable effects
The adverse reactions listed below have been identified from post-marketing reports of Primene administered as a component of parenteral nutrition. The frequency of the adverse drug reactions listed in this section cannot be estimated from the available data.

\*\*Administration of the infusion:\*\*
When used in neonates and children below 2 years of age, protect from light exposure until administration is completed. Exposure of Primene to ambient light, especially after admixture with trace elements and/ or vitamins, generates peroxides and other degradation products that can be reduced by protection from light exposure (see sections 4.2, 4.4 and 6.3).
Allow the solution to reach room temperature before use.
The use of a final filter is required during administration of all formulations containing Primene and trace elements (including copper, iron, or zinc) for removal of visible particulate matter which has been observed in the infusion line for some formulations.
For 2 in 1 (amino acid and carbohydrate) parenteral nutrition solutions, use a ≤1.2 micron filter for removal of particulate matter that may be formed with the use of trace elements (e.g. copper). For 3 in 1 (lipid, amino acid, and carbohydrate) parenteral nutrition solutions, use a 1.2 micron filter for particulate matter removal.
Perform visual inspections for cloudiness or precipitation of the TPN solution, infusion set, catheter and in-line filter after compounding, prior to administration and periodically during administration. If discolouration or precipitation is noted in the filter, perform blood levels of copper (or other trace elements) where medically relevant.
Discard any unused contents. Do not reconnect any partially used container.
Do not connect containers in series in order to avoid air embolism due to possible residual air in the primary container.
Primene must not be infused through the same tubing with blood or blood components unless there is documentation that it is safe.
Attach administration set. Refer to 'Instructions for Use' accompanying the set.

Allow the solution to reach room temperature before use.
The use of a final filter is required during administration of all formulations containing Primene and trace elements (including copper, iron, or zinc) for removal of visible particulate matter which has been observed in the infusion line for some formulations.
For 2 in 1 (amino acid and carbohydrate) parenteral nutrition solutions, use a ≤1.2 micron filter for removal of particulate matter that may be formed with the use of trace elements (e.g. copper). For 3 in 1 (lipid, amino acid, and carbohydrate) parenteral nutrition solutions, use a 1.2 micron filter for particulate matter removal.
Perform visual inspections for cloudiness or precipitation of the TPN solution, infusion set, catheter and in-line filter after compounding, prior to administration and periodically during administration. If discolouration or precipitation is noted in the filter, perform blood levels of copper (or other trace elements) where medically relevant.
Discard any unused contents. Do not reconnect any partially used container.
Do not connect containers in series in order to avoid air embolism due to possible residual air in the primary container.
Primene must not be infused through the same tubing with blood or blood components unless there is documentation that it is safe.
Attach administration set. Refer to 'Instructions for Use' accompanying the set.
