2.1 Dosage
General 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 body weight 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.
The daily dose should not exceed 2 g of ALBUMIN (HUMAN) 20% per kg of body weight.
Hypovolemia
In adults, an intravenous infusion of 25 g should be given. If adequate response (stabilization of circulation) is not achieved within 15 to 30 minutes, an additional dose may be given.
In spite of limited information about the efficacy in pediatric subjects, an intravenous infusion of 2.5 to 12.5 g or 0.5 to 1 g/kg body weight may be given. If adequate response (stabilization of circulation) is not achieved within 15 to 30 minutes, an additional dose may be given.
Hemodilution may follow administration of ALBUMIN (HUMAN) 20%. If hemorrhage has occurred, this may result in relative anemia. This condition should be controlled by the supplemental administration of compatible red blood cells or compatible whole blood.
Hypoalbuminemia
In adults, intravenous infusion of 50 to 75 g of ALBUMIN (HUMAN) 20% may be used. Hypoalbuminemia is usually accompanied by a hidden extravascular albumin deficiency of equal magnitude. This total body albumin deficit must be considered when determining the amount of albumin necessary to reverse the hypoalbuminemia.
In burns, therapy usually starts with the administration of large volumes of crystalloid injection to maintain plasma volume. After 24 hours, ALBUMIN (HUMAN) 20% may be added at an initial dose of 25 g with the dose adjusted thereafter to maintain a plasma protein concentration of 2.5 g per 100 mL or a serum protein concentration of 5.2 g/100 mL.
Prevention of Central Volume Depletion after Paracentesis due to Cirrhotic Ascites
In adults, intravenous infusion of 8 g of ALBUMIN (HUMAN) 20% may be given for every 1,000 mL of ascitic fluid removed.
Ovarian Hyperstimulation Syndrome
In adults, as a guideline, doses of 50 – 100 g of ALBUMIN (HUMAN) 20% should be infused over 4 hours and repeated at 4- to 12-hour intervals as necessary, when infusion of normal saline fails to achieve or maintain hemodynamic stability and urine output. [ 7 ]
Adult Respiratory Distress Syndrome (ARDS)
In adults, a dose of 25 g of ALBUMIN (HUMAN) 20% can be infused over 30 minutes and repeated at 8 hour intervals for 3 days, if necessary. [ 5 ]
Induction of Diuresis in Patients with Acute Nephrosis
In adults, a dose of 25 g of ALBUMIN (HUMAN) 20% can be infused, administered with an appropriate diuretic once a day for 7 to 10 days.
Hemolytic Disease of the Newborn
In newborns, ALBUMIN (HUMAN) 20% may be administered prior to or during exchange transfusion at a dose of 1 g per kilogram body weight. [ 6 ]
2.2 Administration
Intravenous use only.
Prior to administration, parenteral drug products should be inspected visually for turbidity and discoloration, whenever solution and container permit.
Do not dilute with sterile water for injection.
Do not use solutions of ALBUMIN (HUMAN) 20% which are cloudy or have deposits. Once the infusion container has been opened the contents should be used immediately. Discard the unused portion. Filtration of ALBUMIN (HUMAN) 20% is not required.
The infusion rate should be adjusted according to the individual circumstances and the indication. In plasma exchange during paracentesis, the infusion rate may be higher and should be adjusted to the rate of removal.
If large volumes (greater than 1500 ml) are administered, the product should be warmed to room temperature before use.
