ALBUMIN NANOSPHERE PREPARATIONS TO CONTROL BLEEDING FROM SURGICAL OPERATIONS

摘要

The present invention relates to a product, method of making and method of using an albumin sphere suspension for controlling bleeding of a non-thrombocytopenic patient before, during and after surgery. An albumin sphere suspension containing submicron albumin spheres is prepared, with the albumin spheres being capable of controlling bleeding in vivo. The suspension is prepared by mixing at near freezing temperatures an albumin solution, a sub-stabilizing concentration of glutaraldehyde solution and an alcohol solution containing a stabilizing concentration of glutaraldehyde. The mixed suspension is warmed, and glycine and sorbitol being added. Lyophilization of the suspension can be performed for stabilization of the suspension.
