Plasmanate

Generic name: plasma protein fraction (human)
Dosage form: injection

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 is clear and amber colored. 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.

Additionally, the manufacturing process was investigated for its capacity to decrease the infectivity of an experimental agent of transmissible spongiform encephalopathy (TSE), considered as a model for the variant Creutzfeldt-Jakob disease (vCJD) and Creutzfeldt-Jakob disease (CJD) agents. (5-8) The production steps from Pooled Plasma to Effluent IV-1 in the Plasmanate manufacturing process have been shown to decrease TSE infectivity of that experimental model agent (a total of ≥7.0 logs). These studies provide reasonable assurance that low levels of vCJD/CJD agent infectivity, if present in the starting material, would be removed.

Plasmanate - 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.
