Flexbumin 200 g/l solution for infusion
Flexbumin 200 g/l is a solution containing 200 g/l (20%) of total protein of which at least 95% is human albumin.
A bag of 100 ml contains 20 g of human albumin.
A bag of 50 ml contains 10 g of human albumin
The solution is hyperoncotic.
Excipients with known effect:
Solution for infusion.
A clear, slightly viscous liquid; it is almost colourless, yellow, amber or green.
Restoration and maintenance of circulating blood volume where volume deficiency has been demonstrated, and use of a colloid is appropriate.
The choice of albumin rather than artificial colloid will depend on the clinical situation of the individual patient, based on official recommendations.
The concentration of the albumin preparation, dosage and the infusion rate should be adjusted to the patient's individual requirements.
The dose required depends on the size of the patient, the severity of trauma or illness and on continuing fluid and protein losses. Measures of adequacy of circulating volume and not plasma albumin levels should be used to determine the dose required.
If human albumin is to be administered, haemodynamic performance should be monitored regularly; this may include:
- arterial blood pressure and pulse rate
- central venous pressure
- pulmonary artery wedge pressure (PCW-pressure)
- urine output
- clinical signs of cardiac/respiratory failure (e.g.dyspnoea)
- clinical signs of increasing intra-cranial pressure (e.g. headache)
Method of Administration
Flexbumin 200 g/l can be directly administered by the intravenous route, or it can also be diluted in an isotonic solution (e.g. 5 % glucose or 0.9 % sodium chloride).
The infusion rate should be adjusted according to the individual circumstances and the indication.
In plasma exchange the infusion rate should be adjusted to the rate of removal.
Suspicion of allergic or anaphylactic type reactions requires immediate discontinuation of the injection. In case of shock, standard medical treatment for shock should be implemented.
Albumin should be used with caution in conditions where hypervolaemia and its consequences or haemodilution could represent a special risk for the patient. Examples of such conditions are:
- Decompensated cardiac insufficiency
- Oesophageal varices
- Pulmonary oedema
- Haemorrhagic diathesis
- Severe anaemia
- Renal and post-renal anuria
The colloid-osmotic effect of human albumin 200 g/l or 250 g/l is approximately four times that of blood plasma. Therefore, when concentrated albumin is administered, care must be taken to assure adequate hydration of the patient. Patients should be monitored carefully to guard against circulatory overload and hyperhydration.
200 g/l - 250 g/l Human albumin solutions are relatively low in electrolytes compared to the 40 - 50 g/l human albumin solutions. When albumin is given, the electrolyte status of the patient should be monitored and appropriate steps taken to restore or maintain the electrolyte balance. Flexbumin contains 130-160 mmol/l sodium. To be taken into consideration by patients on a controlled sodium diet.
Albumin solutions must not be diluted with water for injections as this may cause haemolysis in recipients.
If comparatively large volumes are to be replaced, controls of coagulation and haematocrit are necessary. Care must be taken to ensure adequate substitution of other blood constituents (coagulation factors, electrolytes, platelets and erythrocytes).
Hypervolaemia may occur if the dosage and rate of infusion are not adjusted to the patient's circulatory situation. At the first clinical signs of cardiovascular overload (headache, dyspnoea, jugular vein congestion), or increased blood pressure, raised venous pressure and pulmonary oedema, the infusion is to be stopped immediately.
Standard measures to prevent infections resulting from the use of medicinal products prepared from human blood or plasma include selection of donors, screening of individual donations and plasma pools for specific markers of infection and the inclusion of effective manufacturing steps for the inactivation/removal of viruses. Despite this, when medicinal products prepared from human blood or plasma are administered, the possibility of transmitting infective agents cannot be totally excluded. This also applies to unknown or emerging viruses and other pathogens.
There are no reports of virus transmissions with albumin manufactured to European Pharmacopoeia specifications by established processes.
It is strongly recommended that every time that Flexbumin 200 g/l is administered to a patient, the name and batch number of the product are recorded in order to maintain a link between the patient and the batch of the product.
No interaction studies of Flexbumin 200 g/l with other medicinal products have been performed.
The safety of Flexbumin 200 g/l for use in human pregnancy has not been established in controlled clinical trials. However, clinical experience with albumin suggests that no harmful effects on the course of pregnancy, or on the foetus and the neonate are to be expected.
The effects of human albumin on fertility have not been studied.
No animal reproduction studies have been conducted with Flexbumin 200 g/l.
Experimental animal studies are insufficient to assess the safety with respect to reproduction, development of the embryo or foetus, the course of gestation and peri- and postnatal development.
However, human albumin is a normal constituent of human blood.
Flexbumin 200 g/l has no influence on the ability to drive and use machines.
Frequency has been evaluated using the following criteria: very common (>1/10), common (>1/100 to <1/10), uncommon (>1/1,000 to <1/100), rare (>1/10,000 to <1/1,000), and very rare (<1/10,000), not known (cannot be estimated from the available data).

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation 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 via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.
Hypervolaemia may occur if the dosage and rate of infusion are too high. At the first clinical signs of cardiovascular overload (headache, dyspnoea, jugular vein congestion), or increased blood pressure, raised central venous pressure and pulmonary oedema, the infusion should be stopped immediately and the patient's haemodynamic parameters carefully monitored.
Pharmacotherapeutic group: plasma substitutes and plasma protein fractions
ATC code: B05AA01.
Human albumin accounts quantitatively for more than half of the total protein in the plasma and represents about 10 % of the protein synthesis activity of the liver.
Physico-chemical data: Human albumin 200 g/l or 250 g/l has a hyperoncotic effect.
The most important physiological functions of albumin result from its contribution to the oncotic pressure of the blood and its transport function. Albumin stabilises circulating blood volume and is a carrier of hormones, enzymes, medicinal products and toxins.
Under normal conditions, the total exchangeable albumin pool is 4 - 5 g/kg body weight, of which 40 to 45 % is present intravascularly and 55 to 60 % in the extravascular space. Increased capillary permeability will alter albumin kinetics and abnormal distribution may occur in conditions such as severe burns or septic shock.
Under normal conditions the average half life of albumin is about 19 days. The balance between synthesis and breakdown is normally achieved by feed-back regulation. Elimination is predominantly intracellular and due to lysosome proteases.
In healthy subjects, less than 10 % of infused albumin leaves the intravascular compartment during the first two hours following infusion. There is considerable individual variation in the effect on plasma volume. In some patients the plasma volume can remain increased for some hours. However, in critically ill patients, albumin can leak out of the vascular space in substantial amounts at an unpredictable rate.
Human albumin is a normal constituent of human plasma and acts like physiological albumin.
In animals, single dose toxicity testing is of little relevance and does not permit the evaluation of toxic or lethal doses or of a dose-effect relationship. Repeated dose toxicity testing is impracticable due to the development of antibodies to heterologous protein in animal models.
To date, human albumin has not been reported to be associated with embryo-foetal toxicity, oncogenic or mutagenic potential.
No signs of acute toxicity have been described in animals models.
