HBOC
Hemoglobin-based oxygen carriers (HBOCs) are a class of artificial blood substitutes. They are made by extracting hemoglobin from bovine or human blood and chemically modifying it into an injectable oxygen-carrying solution, intended to replace the oxygen-carrying function of red blood cells in emergency situations.
Timeline (last 90 days)
Early products of hemoglobin-based oxygen carriers (HBOCs) exposed in clinical trials the problems that free hemoglobin scavenges nitric oxide, causing vasoconstriction and elevated blood pressure and increasing the risk of myocardial infarction and stroke, and that hemoglobin is easily and rapidly cleared by the kidneys in plasma, with a short half-life.
As of now, no hemoglobin-based oxygen carrier (HBOC) has received full FDA approval for clinical use in the United States.
Hemoglobin-based oxygen carriers (HBOCs) are blood substitutes made from free hemoglobin after chemical modification, using chemical modification methods such as cross-linking, polymerization or PEGylation to extend half-life and reduce toxic side effects.
