Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Aminoven.

What is in this leaflet

This leaflet answers some common question about Aminoven. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you being given Aminoven against the benefits this medicine is expected to have for you.

If you have any concerns about this medicine, ask your doctor or pharmacist.

Keep this leaflet. You may need to read it again.

What Aminoven is used for

Aminoven contains amino acids and is an intravenous infusion, which is given as a part of intravenous nutritional therapy. When the intake of nutrients or food into the mouth or directly into the gut is not possible or it is not enough to supply the body’s needs then intravenous nutrients or foods can be given. This is especially important for people whose bodies are under physical stress from illness or recent surgery. During illness or after surgery the body requires nutrition or food. Amino acids are the building blocks used by the body to make proteins. Aminoven is usually given together with carbohydrates, fats, salts, trace elements and vitamins to provide a complete intravenous diet.

Your doctor may have prescribed Aminoven for another reason. Ask your doctor if you have any questions about why Aminoven has been prescribed for you.

Before you are given Aminoven

When should you NOT be given Aminoven? 

You should NOT be given Aminoven if

  • You have an allergy to Aminoven or any of the ingredients listed at the end of this leaflet.
  • You have an inability to break down amino acids.
  • You have severe liver failure.
  • You have severe kidney failure (if dialysis facilities are not available).
  • You have too much fluid in your body.
  • You have too much acid in your blood, also called metabolic acidosis.
  • There is not enough oxygen being supplied to your cells.
  • You are experiencing a sudden decrease in blood pressure.
  • You have certain untreated heart problems.

If you are not sure whether any of these apply to you, check with your doctor.

You must tell your doctor:

  • If you have any allergies to any other medicines or any other substances, such as foods, preservatives or dyes.
  • You have low potassium levels in your body.
  • You have too low sodium levels in your body.
  • You have too much lactic acid in your body.
  • Your blood is very concentrated.
  • You are suffering from a blood disease or an infection of the blood.
  • You have certain untreated heart problems.
  • If you are pregnant or intend to become pregnant. Your doctor will discuss the risks and benefits of using Aminoven during pregnancy.
  • If you are breastfeeding or plan to breastfeed. Your doctor will discuss the risks and benefits of using Aminoven when breastfeeding.
  • If you are under 18 years of age.

If you have not told your doctors about any of the above, tell them before you are given Aminoven.

Taking other medicines

Some medicines can interact or interfere with each other. There are currently no known medicines, which can interfere with or be affected by Aminoven.

Use in Children

Aminoven can be administered to children and adolescents between 2- 18 of years of age.

There is currently not enough information to recommend the use of Aminoven in newborns and children under 2 years of age.

How is Aminoven given

Aminoven is given as a continuous infusion into a central vein. An electronic pump may be used to control the speed of the infusion of drip. Aminoven is usually given as a mixture with glucose, fats, salts, trace elements and vitamins. Aminoven must only be given by a doctor or nurse.

How much is given

Your doctor will decide what dose you will receive. This will depend on your condition, any other diseases you may have and your body weight.

Your doctor will also calculate your requirements for energy, salts, trace elements and vitamins.

How long it is given

The infusion will be continued for as long as your condition requires.

Side Effects

Aminoven, like all other nutrient solutions which are given intravenously, may cause side effects in some people. When Aminoven is correctly administered, there should be no adverse effects however if you experience anything unusual during treatment, tell your doctor immediately.

The adverse effects that occur during overdose (see below) are usually reversible and regress when therapy is discontinued. Infusion via central veins in general may have an increased risk of infection.

If you are given too much (overdose)

This rarely happens as Aminoven is usually administered under the care of a trained professional in a hospital or clinic setting.

However, if you are given Aminoven too quickly or too much, you may experience the following side effects: feeling sick (nausea and vomiting) or shivering.

Your doctor has information on how to recognise and treat an overdose. Ask your doctor if you have any concerns.

Otherwise immediately contact your doctor or a Poisons Information Centre in your country.

(See Section 4.4 Special Warnings and Precautions for Use.)
Additives. Additions should be performed aseptically immediately before the start of the infusion. Discard any residual contents.
All steps of admixing must be performed under strictly aseptic conditions, e.g. using laminar air flow technique, by professionally trained personnel according to individual hospital policy.
Compatibility with Aminoven 10% 1000 mL has been documented for up to the following concentrations:
10% fat emulsion (1000 mL Intralipid 10%);
20% fat emulsion (500 mL Intralipid 20%);
30% fat emulsion (500 mL Intralipid 30%);
fat soluble vitamins (10 mL Vitalipid N Adult);
water soluble vitamins (1 vial Soluvit N);
glucose 20% to 50% (1000 mL);
150 mmol Na+;
5 mmol Ca2+;
150 mmol K+;
5 mmol Mg2+;
286 mmol Cl-;
15 mmol phosphate (organic);

Recommended admixing sequence.

1. Add trace elements and phosphate-free electrolyte solutions to Aminoven.
2. Add phosphate-containing electrolytes to the glucose solution.
3. Transfer the solutions produced in steps 1 and 2 into the ethylvinylacetate (EVA) bag.
4. Reconstitute Soluvit N with Vitalipid N and add to Intralipid.
5. Transfer Intralipid/vitamin mixture to the EVA bag.
6. Mix the contents of the bag by gentle agitation.

Note.

Glucose solutions should not be added directly to Intralipid, but should be mixed with Aminoven first. Electrolytes should never be added directly to Intralipid, but should be diluted in Aminoven and glucose solution before being mixed with the emulsion. If creaming is observed on addition of electrolytes, invert or shake the emulsion before usage. Do not use if inversion or gently shaking does not result in an even mixture. Precipitation of calcium phosphate is possible if both calcium and phosphate ions are added. When a mixture must be stored in the refrigerator for up to 24 hours before use, the vitamins and trace elements should be added just prior to administration.
The use of EVA bags for compounding should follow the manufacturer's instructions under strictly aseptic conditions.
Shelf life after first opening. Aminoven should be used with sterile transfer equipment immediately after opening.
Shelf life after mixing with other components. To reduce microbiological hazard, use as soon as practicable after reconstitution/preparation. If storage is necessary, hold at 2 to 8°C for not more than 24 hours.

4.3 Contraindications

As for all amino acid solutions the administration of Aminoven is contraindicated in the following conditions: disturbances of amino acid metabolism, metabolic acidosis, renal insufficiency without haemodialysis or haemofiltration treatment, advanced liver insufficiency, fluid overload, shock, hypoxia, decompensated heart failure.
The administration of Aminoven 10% is contraindicated in children less than 2 years of age. For children under 2 years, paediatric amino acid preparations should be used, which are formulated to meet their different metabolic needs. No clinical studies have been conducted with Aminoven 10% solution in the paediatric population.

4.4 Special Warnings and Precautions for Use

Aminoven is to be used as part of a comprehensive total parenteral nutrition (TPN) regimen that takes into account the needs of the individual patient: the need for and capacity to tolerate a given dose of TPN depends on the metabolic state of the patient and his/her organ function.
It is necessary to assess vital signs (e.g. well-being, blood pressure, breathing, etc) during TPN. Serum electrolytes, fluid balance and renal function should be properly monitored during administration. Laboratory tests for monitoring should include blood and urine glucose, serum proteins, kidney and liver function tests, serum electrolytes, haemogram, serum and urine osmolarities, and blood urea. Triglycerides should be checked if lipids are administered simultaneously. Aminoven 10% itself has no effect on the triglyceride levels.
Care should be exercised in the administration of large volume infusion fluids to patients with cardiac insufficiency to avoid risk of development of pulmonary oedema.
In cases of hypokalaemia and/or hyponatraemia adequate amounts of potassium and/or sodium should be supplied simultaneously.
Amino acid solutions may precipitate acute folate deficiency, folic acid should therefore be given daily.
Aminoven 10% should always be a part of a TPN regimen and therefore some general precautions would need to be considered. TPN without any oral or enteral concomitant intake of nutrients may lead to jaundice due to cholestasis. This may be reversed by administration of small amounts of oral/enteral intake compatible with tolerability of the gut. This will also have a positive effect on the gut function in general. Jaundice may also appear during TPN without any proven cholestasis and reduction of energy will most of the time reverse this condition if TPN is the real cause. Infusion with a high content of glucose with or without simultaneous administration of lipids results in lipogenesis and fat deposition in the liver. The same can be seen when too much lipids are administered.
All TPN regimens are hypertonic which will result in development of thrombophlebitis as a result of duration of time of infusion (and osmolarity). Central venous catheters may result in central complications like thrombosis with a potential risk of embolism. Extravasation of TPN-admixtures may cause tissue damage. The severity of the damage is dependent on the osmolarity of the fluid, the amount extravasated before stopping the infusion, and the location of extravasation. Areas with a thin subcutaneous layer between the skin and an underlying bone are more vulnerable. Dilution of the extravasated area by using infiltration with physiological saline can be considered but are almost never needed.
TPN should not be administered in patients with septic shock. It is recommended to withhold TPN in the early stage of septicaemia and establish the cause of the condition. If TPN is indicated during a stable and chronic state of sepsis, special attention must be taken to vital signs and a more frequent laboratory monitoring should be done.
There have been no reported allergic reactions from Aminoven 10%, however other components of TPN may cause hypersensitivity.
Aminoven 10% is in the vast majority of cases administered simultaneously with other nutrients. If the amino acid solution as a part of TPN by any reason is given separately in a sequential way, it can result in nausea if the infusion is given too fast. If nausea appears, the infusion should be stopped or slowed down. (See Section 4.9 Overdose).

4.7 Effects on Ability to Drive and Use Machines

The effects of this medicine on a person's ability to drive and use machines were not assessed as part of its registration.

4.8 Adverse Effects (Undesirable Effects)

Adverse events have been reported from the use of Aminoven as a component of parenteral nutrition (PN) in clinical trials. Tables 2-7 list the adverse events reported in several PN clinical studies involving Aminoven 10% and 15%.
Aminoven 15% is first registered in January 1999 and from that time on until the recent PSUR dated July 2006, seventeen serious adverse reactions have been reported, which occurred in an ongoing clinical study investigating intradialytic parenteral nutrition in patients suffering from terminal renal insufficiency and malnutrition (study code: 24332-IDPN). Sixteen of these serious adverse reactions have been assessed as not or unlikely related. One serious adverse reaction (metabolic and nutrition disorders, metabolic disorder) has been assessed as possible related to PN. Underlying diabetes was the major predisposing factor.
Since 3CB Structo EL's first registration in January 2003, only one unlabeled serious adverse reaction (cardiac disorders, palpitation) has been spontaneously reported in the PSURs which has been assessed as possible related to PN by the reporter and probably related to PN by the company.
3CB StructoPeri EL was first registered in October 2003. From that time on no serious adverse reactions have reported in the PSURs.
3CB SMOF EL is not yet registered. Therefore, no PSUR exists registering serious adverse reactions.
3CB SMOF Peri EL is not yet registered. Therefore, no PSUR exists registering serious adverse reactions.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at www.tga.gov.au/reporting-problems.

4.9 Overdose

As with other amino acid solutions, shivering, vomiting, nausea, and increased renal amino acid losses can occur when Aminoven is given in overdose or if the infusion rate is exceeded. Infusion should be stopped immediately in this case. It may be possible to continue with a reduced dosage.
A too rapid infusion can cause fluid overload and electrolyte disturbances. Beside control of electrolytes, it is recommended to monitor acid-base balance, creatinine and urea in blood. The tolerability of amino acid infusion is dependent on the patient's condition; liver and renal functions. This means that even at a dose of 1.0 to 1.5 g amino acids/kg body weight/day can result in overdose for patients during certain conditions. The infusion should not exceed 2.0 g amino acids/kg body weight/day in adults.
There is no specific antidote for overdose. Emergency procedures should be general supportive measures, with particular attention to respiratory and cardiovascular systems.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

The amino acids contained in Aminoven are all naturally occurring physiological compounds. As with the amino acids derived from the ingestion and assimilation of food proteins, parenterally administered amino acids enter the body pool of free amino acids and all subsequent metabolic pathways.

Clinical trials.

Study 00-3CB4-001.

This was a phase III single centre, randomised, open, parallel groups, active controlled study undertaken to compare safety and tolerability (primary objectives) and efficacy (secondary objective) of 3CB Structo EL (test product; group A) to Kabiven G19% (control product; group B) in adult patients who were unable to sustain an adequate oral or enteral food intake for up to 7 days, and who therefore required parenteral nutrition (PN). No formal hypotheses testing were planned. 3CB Structo EL is a three chamber bag containing (in 1970 mL) anhydrous glucose 250 g, Aminoven 10% with electrolytes providing 100 g amino acids, and Structolipid as fat emulsion providing 75 g lipids (structured triglycerides). Kabiven G19% is a three chamber bag containing Vamin 18 Novum as amino acid and electrolyte source, Intralipid 20% as fat source and glucose 19%. Dosage was based on body weight (BW). The products were infused via a central venous line. The intention to treat (ITT) data set (those patients who received at least one dose of study drug) comprised of 19 patients in each group (all Caucasian). The portion of males was higher in group B (63%) than in group A (47%). Mean age of group A or B was 67.8 (SD 13.7) or 56.6 (SD 16.1) years, corresponding mean weight was 65.4 (13.7) vs. 65.3 (18) kg.
Tables 8 and 9 show number of patients and infused volume of study drug during the study period as well as number of infusions.
Mean administered volumes of 1496 or 1526 mL 3CB Structo EL (on days 4 or 5) corresponded to a mean supply of 76 or 77 g amino acids per day. Based on mean BW of 65.4 kg, mean supply of amino acids was 1.2 g/kg BW/day which is in accordance with recommended daily dose of 1-2 g per kg BW. Thirteen patients terminated the study prematurely (inclusive 3 patients that did not receive any study medication) 6 patients in group A and 7 patients in group B.
Safety and tolerance were assessed by adverse event (AE) profile, vital signs and laboratory safety variables in blood, plasma and serum. A total of 27 of the 38 patients experienced at least one AE during the study, 13/19 in group A and 14/19 in group B; AEs of severe intensity were reported for 5 patients in each group. The most frequently reported AEs were dyspepsia (n = 2 vs. n = 3), hyperglycaemia (n = 3 vs. n = 2), lower respiratory tract infection (n = 2 vs. n = 2) and pyrexia (n = 3 vs. n = 1). Two patients from group A experienced a serious adverse event (SAE), aggravated pancreatitis and respiratory failure, respectively in the follow-up period of the study but no SAE occurred in group B. Both patients did not recover from the event and died. These SAEs were not related to the study medication. In group A, 7/19 patients had AEs possibly related to study medication, compared to 4/19 in group B; most frequent events were catheter-related infections (n = 2 vs. n = 1) and hyperglycaemia (n = 3 vs. n = 2), other events were pyrexia (n = 1 each group), hyperkalaemia (n = 1, group A), hypophosphatemia (n = 1, group A) and hypertriglyceridaemia (n = 1, group B). No difference between the treatment groups was considered clinically significant, for any safety laboratory or vital signs parameters.
Efficacy endpoints (secondary) were laboratory variables; no clinical efficacy assessments were performed. No statistical significant differences (student's t-test, p < 0.05) in the plasma concentration of amino acids (LOCF minus period 1) between both treatment groups were determined for most amino acids with two exceptions. Histidine was significantly higher in group B (p = 0.0089) where the mean (SD) values were 26.5 (41.6) vs. -2.9 (20.6) micromol/L, respectively. For taurine a significant higher concentration (p = 0.0373) was found in group A where the mean (SD) values were 18.7 (48.6) vs. -6.7 (15.8) micromol/L. There is a 28% higher concentration of histidine in Kabiven G19% compared to 3CB Structo EL and in addition a higher volume of Kabiven was administered. Taurine is present in 3CB Structo EL but not in Kabiven. No statistical significant differences between the groups were found in serum concentrations of other potential nutritional parameters like pre-albumin and IGF-1.

Study 03-3CB7-001.

This was a phase III, single centre, open, randomized, active controlled study undertaken to compare safety and tolerance of 3CB SMOF EL (test product; group A) with Kabiven G19% (reference product; group B) in post-operative, adult patients of major gastro-intestinal tract surgery requiring parenteral nutrition for at least 5 days. The study was not an efficacy study. 3CB SMOF EL is a three chamber bag containing (in 1970 mL) anhydrous glucose 250 g, Aminoven 10% with electrolytes providing 100 g amino acids and SMOFlipid providing 75 g lipids. SMOFlipid is a fat emulsion containing (in 1000 mL) soya-bean oil 60 g, medium chain triglycerides 60 g, olive oil 50 g and fish oil 30 g. Kabiven G19% (see Study 00-3CB4-001). Dosage was based on body weight (BW). The products were infused via a central venous line. The ITT analysis set comprised of 53 patients (26 in group A and 27 in group B; all Caucasian) who received at least one dose of study medication.
Tables 10 and 11 show number of patients and infused volume of study drug during the study period as well as number of infusions.
The portion of males was higher in group B (77.8%) than in group A (57.7%). Mean age of patients in group A or B was 57.7 (SD 12.6) or 63.0 (SD 10.1) years, corresponding mean weight was 72.4 (11.3) vs. 74.4 (10.2) kg. Mean administered volumes of 1550 or 1755 mL 3CB SMOF EL (on days 3 or 4) corresponded to a mean supply of 79 or 89 g amino acids per day. Based on a mean BW of 72.4 kg, mean supply of amino acids was 1.1 or 1.2 g/kg BW/day which is in accordance with recommended daily dose of 1-2 g per kg BW. Seventeen patients terminated the study prematurely, 8 patients in group A, and 9 patients in group B.
Safety and tolerance were assessed by AE profile, vital signs and laboratory safety variables in blood, plasma and serum. No formal hypothesis testing was planned. 25/26 and 23/27 patients in group A and B, respectively, experienced at least one AE during the study; AEs of severe intensity were reported for 4 patients in each group. AEs concerned most frequently the gastrointestinal system, namely nausea (5/26 or 8/27 patients in group A or B), flatulence (7/26 vs. 4/27 patients), and vomiting NOS (not otherwise specified) (7/26 vs. 3/27 patients). SAEs occurred in 5/26 or 2/27 patients in group A or B. All SAEs were regarded as unlikely related to the study medication. SAEs in both groups consisted predominantly of post-operative complications due to insufficiency of sutures and anastomosis leading to paralytic ileus in one patient. Other patients suffered from local peritonitis, pancreatic fistula, a post-procedural bile leak, peritonism and a nosocomial pneumonia leading to respiratory insufficiency, respectively. In another patient who suffered from a haemorrhage, this event was a direct consequence of the metastatic pancreas carcinoma infiltrating the stomach. Possibly related AEs occurred in 16/26 or 11/27 patients in group A or B. This concerned mostly nausea (4/26 vs. 7/27 patients) and vomiting (7/26 vs. 2/27 patients). In one patient in group A, the AE nausea was regarded as probably related to the study drug. From day 1 to final examination, patients of group A compared to group B showed no noticeable differences regarding the means of the laboratory parameters and vital signs.

5.2 Pharmacokinetic Properties

The amino acids in Aminoven enter the plasma pool of corresponding free amino acids. From the intravascular space, amino acids distribute to the interstitial fluid and, individually regulated for each single amino acid, into the intracellular space of different tissues as required.
Plasma and intracellular free amino acid concentrations are endogenously regulated within narrow ranges, depending on the age, nutritional status and pathological condition of the patient.
Balanced amino acid solutions such as Aminoven do not significantly alter the physiological amino acid pool when infused at a constant and slow infusion rate.
Characteristic changes in the physiological amino acid pool of the plasma are only foreseeable when the regulative function of essential organs like liver and kidneys are seriously impaired. In such cases special formulated amino acid solutions may be recommended for restoring homeostasis.
Only a small proportion of the infused amino acids are eliminated by the kidneys.
For the majority of amino acids plasma half-lives between 10 and 30 minutes have been reported.

5.3 Preclinical Safety Data

Genotoxicity.

No specific studies have been performed.

Carcinogenicity.

No specific studies have been performed.
