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 important that you be administered this medication to help you improve.

It is usually administered along with other nutrition solutions.

You should not be administeredSynthaminif 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).
• If you have any disease in the amino acid metabolism.

Warnings and precautions

Consult your doctor or nurse before starting to useSynthamin

• Synthaminwill 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 undergo 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 monitoredif you have diabetes.
• If you are being administered to a very young child, more controls will be made.
• 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.
• Synthaminshould not be administered simultaneously with, before or after blood administration through the same infusion equipment.

-The concurrent administration of the injectable solutions ofSynthaminwith 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 the bags and infusion equipment) should be protected from exposure to light until the end of administration. Exposure of Synthaminto 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 ofSynthaminwith other medications

Inform your doctor ornurseif you aretakingor havetakenrecentlyor may need to takeany othermedication.

No interactionswithSynthaminhave been studied.

Pregnancy, lactation, and fertility

If you are pregnant or breastfeeding, or think you may be pregnant or intend to become pregnant, consultyour doctor or pharmacist before usingthismedication.

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

Driving and operating machines

Synthamindoes not affect your ability to drive or operate machines.

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 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 meet protein needs and promote a positive nitrogen balance.

Use of higher doses, mainly in children, should be monitored by more frequent laboratory tests. The infusion rate should not exceed 0.1 g/kg per hour. The maximum infusion rate depends on the concentration of amino acids used. In the case of Synthamin 14 (8.5% Amino Acids) it will be 100 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 monitor serum electrolyte levels, particularly phosphate, magnesium, and chloride. In the case of administration of a solution without electrolytes, the patient should be strictly controlled, evaluating their needs for 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-administrationof anintravenous fat emulsion should be evaluated whenlong-term parenteral nutrition is required toprevent essential fatty acid deficiency (EFAD).

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

The solution shouldbe visually inspected for particles and colorbefore administration.

The infusion 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 the infusion.

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 central access 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:

Exposure to light of parenteral nutrition solutions for intravenous use, 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.

2.Ensure there are no leaks, press the Viaflex bag. Check the transparency of the solution, as well as the absence of foreign particles.

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

4.Remove the protector from the outlet tube of the Viaflex bag and the protector from the puncture of the administration equipment. Insert the puncture of the administration equipment into the outlet tube of the Viaflex bag.

5.Follow the administration equipment 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 additivesusing a syringe or a reconstitution device.

Mix the contents of the bag and additives.

Inspect the final mixture for color and foreign particles.

Check for leaks in the bag.

Ensure that the storage conditions for the additive are met.

Administration of the infusion:

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 air residual 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 exposure

to light until the end of administration. 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 exposure to light.
