6. Contents of the package and additional information

Synthamin is a sterile solution that contains a large number of compounds called amino acids. These are the building blocks for proteins that are vital for your body. It also contains some chemical substances called electrolytes, which are very important for your body to function correctly.

Along with other compounds such as minerals and vitamins, it is used to give you direct nutrition (food) through your blood when you cannot take food by mouth. It is essential that you are administered this medication to help you improve.

It is usually administered along with other nutrition solutions.

You should not be administered Synthamin if you have any of the following clinical conditions

• If you are allergic to the active ingredients or to any of the other components of this medication (listed in section 6)

of this medication.

• If you have any disease in the amino acid metabolism.
• If you have high levels of sodium, potassium, magnesium, and/or phosphate in your blood.

Warnings and precautions

Consult your doctor or nurse before starting to use Synthamin

• Synthamin will only be used if the solution is transparent and the container is not damaged.
• If symptoms of respiratory disorders appear.
• If you have a fever or feel unwell.
• You will have regular blood and urine tests to ensure you are receiving the correct amount of the solution. If necessary, you will be given other treatments.
• You will be closely monitored if you have liver, heart, or kidney problems. Please inform your doctor of this.

• You will be closely monitored if you have diabetes.
• If you are a very young child, more controls will be performed.
• If necessary, you may also be given a vitamin called folic acid, fatty acids (the building blocks of fats), and sugar solutions (such as glucose) to ensure your body has all the necessary elements for good health.
• Synthamin should not be administered simultaneously with, before, or after blood transfusion through the same infusion equipment.
• The concomitant administration of Synthamin solutions with concentrated glucose solutions may lead to hyperglycemia, glycosuria, and hyperosmolar syndrome. Therefore, in patients receiving this treatment, routine blood and urine glucose control should be performed. In certain patients, exogenous insulin may be necessary.

• If any abnormal sign or symptom of hypersensitivity or allergic reaction is observed, the infusion should be stopped immediately.

When used in newborns and children under 2 years, the solution (in bags and administration equipment) should be protected from exposure to light until the end of administration. Exposure of Synthamin to ambient light, especially after mixing it with oligoelements or vitamins, generates peroxides and other degradation products that can be reduced if the product is protected from exposure to light.

Use of Synthamin with other medications

Inform your doctor or nurse if you are taking or have taken recently or may need to take any other medication.

No interactions with Synthamin have been studied.

Due to the content of potassium in Synthamin, special care is necessary in patients treated with potassium-sparing diuretics (e.g. amiloride, spironolactone, triamterene), with angiotensin-converting enzyme inhibitors, with angiotensin II receptor antagonists, or with immunosuppressants tacrolimus or cyclosporin due to the risk of hyperkalemia.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, or think you may be pregnant or plan to become pregnant, consult your doctor or pharmacist before using this medication.

The safety of amino acid solutions in pregnant women or during breastfeeding has not been demonstrated. Your doctor will carefully evaluate the benefits and potential risks before prescribing Synthamin.

Driving and operating machinery

Synthamin does not affect your ability to drive or operate machinery

Use in Adults

Your doctor will determine a perfusion rate based on your needs and clinical condition, which will depend on your weight, your body's needs, the amount of sugar solution (such as glucose) you can receive, and the reason for your treatment.

The solution will be administered through a slow drip injection (called perfusion) through a plastic tube carefully placed in a large vein in your chest (the vena cava). The drip rate will not exceed 70 ml per hour, and you will not receive more than 40 ml per kilogram of body weight per day.

You will not receive blood transfusions through this tube.

Use in Children

When used in newborns and children under 2 years old, the solution (in the bags and administration equipment) must be protected from exposure to light until the end of administration (see section 2).

In children, the parenteral nutrition dose must be adjusted individually based on the patient's requirements for amino acids, electrolytes, and energy.

If You Are Given More Synthamin Than You Should

Since your doctor will be administering Synthamin to you, it is unlikely that you will receive too much. However, if you think you have received more than you should, tell your doctor or nurse.

In case of overdose or accidental ingestion, consult the Toxicology Information Service. Phone 915.620.420

Dosage and administration

Dosage

The total daily dose of these solutions depends on the patient's metabolic needs and clinical response.

Probably, the best procedure to set individual nitrogen needs is to determine the fluid balance. Daily doses of amino acids of approximately 1.0-1.5 g/kg in adults and 2-3 g/kg in children, with an adequate amount of calories (about 180 Kcal/g of nitrogen or +/-30 Kcal/g of amino acids) are generally sufficient to cover protein needs and promote a positive nitrogen balance.

The use of higher doses, mainly in children, should be controlled by more frequent laboratory tests. The perfusion rate should not exceed 0.1 g/kg per hour. The maximum perfusion rate depends on the concentration of amino acids used. In the case of Synthamin 17 (10% Amino Acids) it will be 70 ml/h.

It is necessary to ensure the maintenance of serum potassium levels. An amount of potassium equivalent to 60-180 mEq/day may be indicated. It may be useful to add electrolytes and potassium, depending on the amount of carbohydrates administered and metabolized by the patient. It is essential to frequently control serum electrolyte levels, mainly phosphate, magnesium, and chloride. In the case of administering a solution without electrolytes, the patient should be strictly controlled, evaluating their needs in electrolytes.

Individually, vitamins, oligoelements, and other components (including glucose and lipids) may be added to the parenteral nutrition regimen to meet nutritional needs and prevent deficiencies and the development of complications.

The co-administration of an oily emulsion should be evaluated when prolonged parenteral nutrition is required to prevent essential fatty acid deficiency (EFAD).

In the case of peripheral administration, the osmolality of the solution should be taken into account.

The solution should be visually inspected for particles and color before administration.

The perfusion rate of the solution should be gradually increased during the first hour, and adjusted according to the dose to be administered, the daily volume indicated, and the duration of perfusion.

The use of a final filter during the administration of parenteral nutrition solutions is recommended.

Administration

The hypertonic amino acid and glucose mixtures are preferably administered through a central catheter. If the central route is not indicated, they can be administered peripherally to patients who require parenteral nutrition, amino acid solutions with glucose solutions of appropriate concentration, at the same time as lipid emulsions.

Do not administer unless the solution is clear and colorless or slightly yellow and the package is in good condition.

When used in newborns and children under 2 years, the solution (in bags and administration equipment) should be protected from light exposure until the end of administration.

Special warnings and precautions for use:

The exposure of parenteral nutrition solutions for intravenous use to light, especially after mixing with oligoelements or vitamins, may have adverse effects on the clinical outcome of newborns due to the generation of peroxides and other degradation products.

When used in newborns and children under 2 years, Synthamin should be protected from ambient light until the end of administration.

Handling and preparation

Instructions for use of the Viaflex bag

Use an aseptic technique.

1. Remove the Viaflex bag from its protective overbag at the time of use. Discard the oxygen-absorbing bag.

1. Ensure the absence of leaks by pressing the Viaflex bag. Check the transparency of the solution and the absence of foreign particles.

1. Hang the Viaflex bag. Prepare the administration equipment and close the flow regulator.

1. Remove the protective cap from the outlet tube of the Viaflex bag and the protective cap from the administration equipment's injection port. Insert the administration equipment's injection port into the outlet tube of the Viaflex bag.

1. 5. Follow the administration equipment's instructions to purge it and administer the solution.

In the case of additions to the bag:

Use an aseptic technique.

Verify the stability and compatibility of the additives.

Prepare the injection point of the bag.

Puncture the injection point and inject the additives using a syringe or a reconstitution device.

Mix the contents of the bag and additives.

Inspect the final mixture for color and foreign particles.

Check the absence of leaks in the bag.

Ensure that the storage conditions for the additive are met.

Administration of the perfusion:

Do not administer blood before, at the same time, or after, through the same equipment due to the risk of pseudoagglutination.

Do not connect bags in series to avoid gas embolism due to residual air in the primary packaging.

Discard after single use.

Discard any remaining portion.

Do not reconnect partially used bags.

Special precautions for disposal and other manipulations:

When used in newborns and children under 2 years, it should be protected from light exposure until the end of administration. The exposure of Synthamin to ambient light, especially after mixing with oligoelements or vitamins, generates peroxides and other degradation products that can be reduced if the product is protected from light exposure.
