Plasmanate

Description

This product has been prepared from large pools of human plasma. Each 100 mL of Plasma Protein Fraction (Human) 5%, USP--Plasmanate contains 5 g selected plasma proteins buffered with sodium carbonate and stabilized with 0.004 M sodium caprylate and 0.004 M acetyltryptophan. The plasma proteins consist of approximately 88% normal human albumin, 12% alpha and beta globulins and not more than 1% gamma globulin as determined by electrophoresis. 1 The concentration of these proteins is such that this solution is iso-oncotic with normal human plasma and is isotonic. The approximate concentrations of the significant electrolytes in Plasmanate are: sodium 145 mEq/L, potassium 0.25 mEq/L, and chloride 100 mEq/L. Plasmanate must be administered intravenously.

This product is designed to bring to the medical profession a preparation derived from human blood and similar to human plasma. Each vial of Plasmanate is sterile and heat-treated at 60°C for 10 hours against the possibility of transmitting the hepatitis viruses.

The blood group agglutinins and agglutinogens A and B are at such a low level in Plasmanate solution that its use has no effect on routine blood typing procedures. No chemical or microscopic alterations of the urine have been observed with its use.

Clinical Pharmacology

In normal human volunteers, Plasmanate has resulted in an increased blood volume which has lasted up to 48 hours. 2 Clinical experience has indicated that it is an adequate replacement for human plasma in the treatment of shock and is a suitable means of providing human proteins for their osmotic effect.

Indications and Usage

Treatment of Shock --Plasmanate is indicated in the treatment of shock due to burns, crushing injuries, abdominal emergencies, and any other cause where there is a predominant loss of plasma fluids and not red blood cells. It is also effective in the emergency treatment of shock due to hemorrhage. 3,4 Following the emergency phase of therapy, blood transfusions may be indicated depending on the severity of the blood loss.

In infants and small children, Plasmanate has been found to be very useful in the initial therapy of shock due to dehydration and infection.

Contraindications

Plasmanate is contraindicated for use in patients on cardiopulmonary bypass. Severe hypotension has been reported in such patients when given Plasma Protein Fraction. 4

Plasma Protein Fraction is contraindicated in patients with severe anemia, congestive heart failure, or increased blood volume.

Warnings

Plasmanate 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 are turbid or 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. Plasmanate contains no preservative.

Precautions

General

Rapid infusion of Plasmanate (greater than 10mL/minute) has produced hypotension in patients undergoing surgery or in the preoperative or postoperative period. Blood pressure should be monitored during use and infusion slowed or ceased if sudden hypotension occurs.

Plasmanate does not provide coagulation factors and therefore does not correct coagulation disorders.

Drug Interactions

Plasma Protein Fraction (Human) 5%, USP--Plasmanate is compatible with whole blood, packed red cells as well as the standard carbohydrate and electrolyte solutions intended for intravenous use. It should, however, not be mixed with protein hydrolysates or solutions containing alcohol.

Pregnancy Category C

Animal reproduction studies have not been conducted with Plasmanate. It is also not known if Plasmanate can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Plasmanate 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

Hypotension may occur, particularly following rapid infusion or intraarterial administration to patients on cardiopulmonary bypass. The blood pressure may normalize spontaneously after the slowing or discontinuation of the infusion. Vasopressors will also correct the hypotension.

Flushing, urticaria, back pain, nausea and headache have been occasionally reported by conscious patients.

Dosage and Administration

Dosage is based almost entirely on the nature of the individual case and response to therapy. The usual minimum effective dose in adults is 250-500 mL. As with any plasma expander, the rate should be adjusted or slowed according to the clinical response and rising blood pressure.

Administration should be by vein and preferably through an area of skin at some distance from any site of infection or trauma. Plasmanate is compatible with the usual carbohydrate and electrolyte solutions.

We recommend the following procedure: First swab the stopper with Iodine Tincture, USP followed by a sterile antiseptic swab.

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.

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.

How Supplied

Plasmanate is available in 50 mL pediatric size, 250 mL and 500 mL rubber-stoppered vials. Each single dose vial contains plasma protein in the following approximate amounts:

NDC Number   Size   Grams Protein
13533-613-20  50 mL  2.5
13533-613-25 250 mL 12.5
13533-613-27 500 mL 25.0

STORAGE

Store at room temperature not exceeding 30°C (86°F). Solution that has been frozen should not be used. Do not use after expiration date.

CAUTION

Rx only

U.S. federal law prohibits dispensing without prescription.
