Freeze-dried plasma formats for the trauma care field
View Patent ↗Disclosed are freeze-dried plasma formats specifically designed for the trauma care field. Blood plasma is subjected to a glucose removal step, a protein fraction up-concentration step and addition of stabilizers prior to freeze-drying. Preferable stabilizers are glutamine dipeptides, glutamine and glycine. The glutamine based formulation is added direct to plasma and serves three main purposes: 1) Increases stability of plasma proteins and stabilizes pH in freeze-dried state; 2) Increases stability of plasma proteins against Gamma Irradiation and thus allows for the application of a terminal sterilization step; 3) Introduces supplements beneficial to the trauma patient.

13. The composition of claim 12 , further comprising an amino acid-based buffer which is added prior to freeze-drying.
14. The composition of claim 13 , wherein the amino acid-based buffer is selected from the group consisting of N,N-Bis(2-hydroxyethyl)glycine, N,N-Bis(2-hydoxyethyl)taurine, glycineamide, and combinations thereof.
15. The composition of claim 13 , wherein the amino acid-based buffer comprises taurine and N,N-Bis(2-hydroxyethyl)taurine or bicine.
16. The composition of claim 12 , wherein the at least one stabilizer is selected from the group consisting of glutamine-containing dipeptides, dipeptides, antioxidants, and combinations thereof.
17. The composition of claim 16 , wherein said dipeptide is a glutamine-containing dipeptide or a glycine dipeptide.
18. The composition of claim 12 , which is subjected to high dose gamma irradiation and heat treatment as terminal sterilization methods.
