1. What ISOPURAMIN is and what it is used for

ISOPURAMIN contains amino acids (substances used by your body for protein production).
ISOPURAMIN is used to provide food (nutrition) directly into the bloodstream when sufficient amounts cannot be taken by mouth. This means it is administered through a vein, together with solutions rich in sugars and fats, in addition to salts, vitamins, and trace elements, in order to meet nutritional requirements.
ISOPURAMIN is indicated in adults and children:

  • If you are in a state of malnutrition of various origins,
  • If you are about to undergo or have recently undergone surgery,
  • If you have extensive burns,
  • If you suffer from a severe liver disease (decompensated liver cirrhosis),
  • If you suffer from a kidney disease (nephrotic syndrome without renal insufficiency, acute and chronic uremia undergoing periodic peritoneal dialysis or extracorporeal dialysis), and are also undergoing dialysis, a blood filtration method,
  • If you are in a condition requiring a significant nitrogen supply for protein rebuilding.
    Consult your doctor if you do not feel better or if you feel worse.

2. What you need to know before ISOPURAMIN is administered to you

You must not be given ISOPURAMIN

  • If you are allergic to one or more of the amino acids or to any of the other ingredients of this medicine (listed in section 6).
  • If you are not producing urine (acute and chronic uraemia under conservative medical treatment).
  • If you are dehydrated.
  • If you have severe liver disease (hepatic coma).
  • If you have high levels of sodium in your blood.
  • If you have a disorder related to amino acid metabolism.

Warnings and precautions
Talk to your doctor or nurse before ISOPURAMIN is administered to you.
When used in children under 2 years of age, the solution (in bottles and administration sets) must be protected from light exposure until administration is complete. Exposure of Isopuramin 10% to ambient light, especially after addition of trace elements and/or vitamins, may generate peroxides and other degradation products, which can be minimized by protecting from light.
If you experience any unusual signs or symptoms of an allergic reaction, such as fever, chills, skin rash, difficulty breathing, excessive sweating, nausea or headache, contact your doctor or nurse immediately: the infusion will be stopped immediately.
ISOPURAMIN may cause formation of precipitates in the blood. If you begin to experience difficulty breathing or shortness of breath, contact your doctor or nurse immediately: the infusion will be stopped immediately and additional treatment may be required.
Some medicines and medical conditions may increase the risk of developing infections or sepsis (bacteria in the blood). There is a particular risk of infection or sepsis when a tube (intravenous catheter) is placed into a vein. Your doctor will carefully examine you to assess for any signs of infection.
If you are severely malnourished and require intravenous feeding, parenteral nutrition should be started slowly and carefully.
ISOPURAMIN may cause a stinging sensation and redness at the site of intravenous administration when given in the arm.
Your doctor will monitor your condition during infusion, especially if you currently have liver, kidney, heart or circulatory problems.
Amino acid solutions may increase levels of ammonia or nitrogen-containing compounds in the blood. Your doctor will monitor your blood tests accordingly.
Your doctor must be informed of any serious medical conditions you have that affect fluids, sugars, fats, proteins, and salts (metabolic disorders). These conditions should be corrected before starting ISOPURAMIN.
Inform your doctor if you have or have had:

  • Allergic reaction during infusion. The infusion will be stopped immediately.
  • Liver disease or liver failure.
  • Heart failure (special monitoring may be required in the above conditions).
  • Haemodialysis. The maximum volume of infusion that you can tolerate should be taken into consideration.

During the infusion, blood and urine samples will be taken to monitor:

  • Fluid volume in the body;
  • Levels of chemical substances in blood and urine;
  • Acid-base balance (acidity in blood and urine);
  • Liver and kidney function

Children and adolescents
Your doctor will perform frequent blood tests in your child to monitor blood nitrogen levels, in order to prevent hyperammonaemia (elevated nitrogen levels in blood), which may occur during prolonged treatment. Blood electrolyte levels should also be monitored to ensure they remain within acceptable ranges.
Elderly
Your doctor will ensure that elderly patients undergo frequent blood tests to monitor blood nitrogen levels, in order to prevent hyperammonaemia (elevated nitrogen levels in blood), which may occur during prolonged treatment.

DOSAGE, METHOD AND DURATION OF ADMINISTRATION
Dosage depends on the patient's clinical condition, according to medical prescription. It is advisable to start infusion at less than 40 drops per minute.
For proper nutritional therapy with Isopuramin 10%, it is recommended to administer 35–45 kcal/kg/day in the form of glucose or lipids. In such cases, administration of insulin, potassium, sodium, chloride, phosphorus, magnesium, and other elements should be considered based on clinical requirements. Dosage depends on the patient's clinical condition, according to medical prescription.
The initiation of parenteral nutrition, as well as dosage (dose and frequency of administration), depends on the following patient characteristics:

  • age, weight, clinical condition,
  • nitrogen requirements,
  • metabolic capacity,
  • supplementary nutrition that may be provided via parenteral and/or enteral routes.

As determined individually, vitamins, trace elements, and other components (including glucose and lipids) may be added to the parenteral nutrition regimen to meet nutritional needs and prevent deficiencies and complications. When prolonged parenteral nutrition is required, concomitant administration of a fat emulsion should be considered to prevent essential fatty acid deficiency.

Method of administration
Isopuramin 10% is intended for intravenous use.
The osmolarity of a specific infusion solution must be considered when evaluating peripheral administration.
Highly hypertonic parenteral solutions (>900 mOsm/l) must be administered through a central venous catheter with the tip positioned in a large central vein.
Flow rate should be adjusted according to the administered dose, daily volume intake, and duration of infusion.
Parenteral medicinal products should be visually inspected for the presence of particles and discoloration prior to administration.
When used in children under 2 years of age, the solution (in bottles and administration sets) must be protected from light exposure until the end of administration.

Special warnings and precautions for use
Exposure to light of parenteral intravenous nutrition solutions, especially after addition of trace elements and/or vitamins, may lead to the formation of peroxides and other degradation products.
When used in children under 2 years of age, Isopuramin 10% must be protected from ambient light until the end of administration.

Special precautions for disposal and handling:
When used in children under 2 years of age, protect from light exposure until the end of administration.
