  • DESCRIPTION

    Albumin (Human) 5%, USP (Plasbumin ® -5) is made from pooled human venous plasma using the Cohn cold ethanol fractionation process. Part of the fractionation may be performed by another licensed manufacturer. It is prepared in accordance with the applicable requirements established by the U.S. Food and Drug Administration.

    Plasbumin-5 is a 5% sterile solution of albumin in an aqueous diluent. The preparation is stabilized with 0.004 M sodium caprylate and 0.004 M acetyltryptophan. The aluminum content of the product is not more than 200 µg/L. The approximate sodium content of the product is 145 mEq/L. It contains no preservative. Plasbumin-5 must be administered intravenously.

    Each vial of Plasbumin-5 is heat-treated at 60°C for 10 hours against the possibility of transmitting the hepatitis viruses.

    CLINICAL PHARMACOLOGY

    Plasbumin-5 is oncotically equivalent volume for volume to normal human plasma.

    When administered intravenously to an adequately hydrated subject, the oncotic (colloid osmotic) effect of Plasbumin-5 is to expand the circulating blood volume by an amount approximately equal to the volume infused. It is primarily used in the treatment of shock associated with hemorrhage, surgery, trauma, burns, bacteremia, renal failure, and cardiovascular collapse. 1

    Albumin is a transport protein and it may be useful in severe jaundice in hemolytic disease of the newborn. 2 This could also be of importance in acute liver failure where albumin might serve the dual role of supporting plasma oncotic pressure, as well as binding excessive plasma bilirubin. 1

    INDICATIONS AND USAGE

    Emergency Treatment of Hypovolemic Shock

    Plasbumin-5 is iso-oncotic with normal plasma and on intravenous infusion will expand the circulating blood volume by an amount approximately equal to the volume infused. In conditions associated mainly with a volume deficit, albumin is best administered as a 5% solution (Plasbumin-5); but where there is an oncotic deficit, Albumin (Human) 25%, USP (Plasbumin ® -25) may be preferred. This is also an important consideration where the treatment of the shock state has been delayed. If Plasbumin-25 is used, appropriate additional crystalloid should be administered. 1

    Crystalloid solutions in volumes several times greater than that of Plasbumin-5 may be effective in treating shock in younger individuals who have no preexisting illness at the time of the incident. Older patients, especially those with preexisting debilitating conditions, or those in whom the shock is caused by a medical disorder, or where the state of shock has existed for some time before active therapy could be instituted, may not tolerate hypoalbuminemia as well. 1

    Removal of ascitic fluid from a patient with cirrhosis may cause changes in cardiovascular function and even result in hypovolemic shock. In such circumstances, the use of albumin infusion may be required to support the blood volume. 1

    Burn Therapy

    An optimal therapeutic regimen with respect to the administration of colloids, crystalloids, and water following extensive burns has not been established. During the first 24 hours after sustaining thermal injury, large volumes of crystalloids are infused to restore the depleted extracellular fluid volume. Beyond 24 hours, albumin can be used to maintain plasma colloid osmotic pressure. Plasbumin-25 may be preferred for this purpose. 1

    Cardiopulmonary Bypass 1

    With the relatively small priming volume required with modern pumps, preoperative dilution of the blood using albumin and crystalloid has been shown to be safe and well-tolerated. Although the limit to which the hematocrit and plasma protein concentration can be safely lowered has not been defined, it is common practice to adjust the albumin and crystalloid pump prime to achieve a hematocrit of 20% and a plasma albumin concentration of 2.5 g per 100 mL in the patient.

    Acute Liver Failure 1

    In the uncommon situation of rapid loss of liver function, with or without coma, administration of albumin may serve the double purpose of supporting the colloid osmotic pressure of the plasma as well as binding excess plasma bilirubin.

    Sequestration of Protein Rich Fluids 2

    This occurs in such conditions as acute peritonitis, pancreatitis, mediastinitis, and extensive cellulitis. The magnitude of loss into the third space may require treatment of reduced volume or oncotic activity with an infusion of albumin.

    Situations in Which Albumin Administration is Not Warranted 1

    In chronic nephrosis, infused albumin is promptly excreted by the kidneys with no relief of the chronic edema or effect on the underlying renal lesion. It is of occasional use in the rapid "priming" diuresis of nephrosis. Similarly, in hypoproteinemic states associated with chronic cirrhosis, malabsorption, protein losing enteropathies, pancreatic insufficiency, and undernutrition, the infusion of albumin as a source of protein nutrition is not justified.

    CONTRAINDICATIONS

    Certain patients, e.g., those with a history of congestive cardiac failure, renal insufficiency or stabilized chronic anemia, are at special risk of developing circulatory overload. A history of allergic reaction to albumin is a specific contraindication for usage.

    WARNINGS

    Plasbumin-5 is made from human plasma. Products made from human plasma may contain infectious agents, such as viruses, that can cause disease. The risk that such products will transmit an infectious agent has been reduced by screening plasma donors for prior exposure to certain viruses, by testing for the presence of certain current virus infections, and by inactivating and/or removing certain viruses. Despite these measures, such products can still potentially transmit disease. There is also the possibility that unknown infectious agents may be present in such products. Individuals who receive infusions of blood or plasma products may develop signs and/or symptoms of some viral infections, particularly hepatitis C. ALL infections thought by a physician possibly to have been transmitted by this product should be reported by the physician or other healthcare provider to Talecris Biotherapeutics, Inc. [1-800-520-2807].

    The physician should discuss the risks and benefits of this product with the patient, before prescribing or administering it to the patient.

    Solutions which have been frozen should not be used. Do not use if turbid. Do not begin administration more than 4 hours after the container has been entered. Partially used vials must be discarded. Vials which are cracked or which have been previously entered or damaged should not be used, as this may have allowed the entry of microorganisms. Plasbumin-5 contains no preservative.

    PRECAUTIONS

    General

    Patients should always be monitored carefully in order to guard against the possibility of circulatory overload. Albumin (Human) 5%, USP (Plasbumin ® -5) is iso-oncotic with normal plasma and will not tend to aggravate tissue dehydration. Appropriate additional crystalloids should be administered, if required by the patient, to maintain normal fluid balance.

    In hemorrhage, the administration of albumin should be supplemented by the transfusion of whole blood to treat the relative anemia associated with hemodilution. 3 When circulating blood volume has been reduced, hemodilution following the administration of albumin persists for many hours. In patients with a normal blood volume, hemodilution lasts for a much shorter period. 4-6 The rapid rise in blood pressure, which may follow the administration of a colloid with positive oncotic activity, necessitates careful observation to detect and treat severed blood vessels which may not have bled at the lower blood pressure.

    Drug Interactions

    Plasbumin-5 is compatible with whole blood and packed red cells, as well as the standard carbohydrate and electrolyte solutions intended for intravenous use. It should not be mixed with protein hydrolysates, amino acid solutions nor those containing alcohol.

    Pregnancy Category C

    Animal reproduction studies have not been conducted with Plasbumin-5. It is also not known whether Plasbumin-5 can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Plasbumin-5 should be given to a pregnant woman only if clearly needed.

    Pediatric Use

    Safety and effectiveness in the pediatric population have not been established.

    ADVERSE REACTIONS

    Adverse reactions to albumin are rare. Such reactions may be allergic in nature or be due to high plasma protein levels from excessive albumin administration. Allergic manifestations include urticaria, chills, fever, and changes in respiration, pulse and blood pressure.

    DOSAGE AND ADMINISTRATION

    Plasbumin-5 should always be administered by intravenous infusion. The choice between the use of Plasbumin-5 and Albumin (Human) 25%, USP (Plasbumin ® -25) depends upon whether the patient requires primarily volume (Plasbumin-5) or primarily colloid osmotic activity (Plasbumin-25). Below a serum oncotic level of 20 mm Hg (equal to a total serum protein concentration of 5.2 g per 100 mL) there is evidence which suggests that the risk of complications increases. 1 When the oncotic pressure drops below this level, the patient should be treated with Plasbumin-25 together with diuretics. This is especially important in high risk patients who have undergone abdominal, cardiovascular, thoracic or urologic surgery or who have acute bacteremia.

    The volume administered and the speed of administration should be adapted to the response of the individual patient.

    A number of factors beyond our control could reduce the efficacy of this product or even result in an ill effect following its use. These include improper storage and handling of the product after it leaves our hands, diagnosis, dosage, method of administration, and biological differences in individual patients. Because of these factors, it is important that this product be stored properly and that the directions be followed carefully during use.

    Hypovolemic Shock

    The volume infused should be related to the estimated volume deficit and the speed of administration adapted to the response of the patient.

    In neonates or infants, Plasbumin-5 may be given in large amounts. 7 The recommended dose is 10 to 20 mL/kg equivalent to 0.5 to 1.0 g albumin/kg body weight.

    Burns

    After a burn injury (usually beyond 24 hours) there is a close correlation between the amount of albumin infused and the resultant increase in plasma colloid osmotic pressure. The aim should be to maintain the plasma albumin concentration in the region of 2.5 ± 0.5 g per 100 mL with a plasma oncotic pressure of 20 mm Hg (equivalent to a total plasma protein concentration of 5.2 g per 100 mL). 1 This is best achieved by the intravenous administration of Plasbumin, usually as Plasbumin-25. The duration of therapy is decided by the loss of protein from burned areas and in the urine. In addition, oral or parenteral feeding with amino acids should be initiated, as the long-term administration of albumin should not be considered as a source of nutrition.

    Other dosage recommendations are given under the specific

    Preparation for Administration

    Remove seal to expose stopper. Always swab stopper top immediately with suitable antiseptic prior to entering vial.

    Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

    Only 16 gauge needles or dispensing pins should be used with 20 mL vial sizes and larger. Needles or dispensing pins should only be inserted within the stopper area delineated by the raised ring. The stopper should be penetrated perpendicular to the plane of the stopper within the ring.
