Dextran is a complex branched polysaccharide used as a plasma volume expander for hypovolemia and in some cases to improve blood flow and prevent thrombosis. It has been used particularly in settings of blood loss or shock, but its use has declined as safer alternatives have become available. Dextran is still used in clinical practice in some countries, mostly as Dextran 40 or Dextran 70 intravenous solutions.
Pharmacokinetics
Intravenous dextran (Dextran 70) pharmacokinetics in adult human volunteers; typical parameters after infusion of 1000 mg/kg.
