Albumin (Human)

What it is and how it works

Mechanism of Action Human albumin accounts for more than half of the total protein in the plasma and represents about 10% of protein synthesis activity by the liver. Human Albumin 25% has a corresponding hyperoncotic effect. The primary physiological function of albumin results from its contribution to plasma colloid oncotic pressure and transport function. Albumin stabilizes circulating blood volume and is a carrier of hormones, enzymes, medicinal products and toxins. Other physiological functions include antioxidant properties, free radical scavenging, and capillary membrane integrity.

Indications

25% is a 25% albumin solution indicated for adults and children : Hypovolemia Ascites Hypoalbuminemia including from burns Acute Nephrosis Acute Respiratory Distress Syndrome (ARDS) Cardiopulmonary Bypass Hypovolemia ALBUMINEX 25% is indicated for restoration and maintenance of circulating blood volume where volume deficiency has been demonstrated, and use of a colloid is appropriate e.g. hypovolemia following shock due to trauma or sepsis, in surgical patients and in other similar conditions with volume deficiency when restoration and maintenance of circulating blood volume is required in both adult and pediatric patients. In pediatric patients to reverse hypovolemia and achieve normal capillary refill time. 1, 2, 3, 4, 5, 6, 7, 8 Ascites ALBUMINEX 25% is indicated for prevention of central volume depletion and maintenance of cardiovascular function after large volume parencentesis in patients with liver cirrhosis or other chronic liver disease in adults and children.

Dosage and administration (summary)

For intravenous administration only. For intravenous use only. ALBUMINEX 25% may be diluted with 0.9% saline or 5% dextrose (glucose). Dosage and infusion rate should be adjusted to the patient's individual requirements. Indication Dose Hypovolemia Adults: Initial dose of 25 g (including renal dialysis). For acute liver failure: initial dose of 12 to 25 g. Prevention of central volume depletion after paracentesis due to cirrhotic ascites Adults: 8 g for every 1000 mL of ascitic fluid removed. Hypoalbuminemia including from burns Adults: 50 to 75 g For pre- and post-operative hypoproteinemia: 50 to 75 g.

Contraindications

25% is contraindicated in patients with: Hypersensitivity to human albumin or any of the excipients Severe anemia or cardiac failure with normal or increased intravascular volume Hypersensitivity to human albumin or the excipients Severe anemia or cardiac failure with normal or increased intravascular volume

Warnings and precautions

Suspicion of allergic or anaphylactic reactions requires immediate discontinuation of the injection and implementation of appropriate medical treatment. Hypervolemia may occur if the dosage and rate of infusion are not adjusted to the patient's volume status. Use with caution in conditions where hypervolemia and its consequences or hemodilution could represent a special risk to the patient. When concentrated albumin is administered, care must be taken to assure adequate hydration of the patient.

Pregnancy

Pregnancy Risk Summary There are no data with ALBUMINEX 25% use in pregnant women to inform on drug-associated risk. Animal reproduction studies have not been conducted using ALBUMINEX 25%. It is not known whether ALBUMINEX 25% can cause fetal harm when administered to a pregnant woman or can affect fertility.

Storage and supply

Storage and handling Do not store above 30°C (86°F). Keep the vial stored in the outer carton in order to protect from light. Do not freeze. Do not use ALBUMINEX 25% after the expiration date which is stated on the carton and label after "EXP." The expiration date refers to the last day of that month.
