This has led to the development of "LIPIDOSE," a protein-free phospholipid emulsion. The proposed mechanism of action of this compound is via remodeling of the infused phospholipids into lipoproteins, thereby increasing lipoprotein and phospholipid content and facilitating greater endotoxin binding and neutralization. "LIPIDOSE" has undergone extensive testing in both animals and humans, and has been found to significantly increase serum phospholipid and lipoprotein concentrations, improve survival in a lethal animal model of septic peritonitis, and mitigate the symptoms of endotoxemia in healthy volunteers.
