Pentastarch is a synthetic colloid volume expander that is used to maintain vascular volume in animals with circulatory shock. It is prepared from hydroxyethyl starch and is derived from amylopectin. There are two hydroxyethyl starch preparations: hetastarch and pentastarch. Hetastarch (6%) has an average molecular weight of 450,000 and colloid osmotic pressure of 32.7. Pentastarch (10%) has an average molecular weight of 280,000 and colloid osmotic pressure of 40. Because hetastarch is a larger molecular weight compound than pentastarch, it tends to remain in the vasculature and prevent loss of intravascular volume and tissue edema. After administration, pentastarch will be retained in the vasculature and prevent loss of intravascular volume and tissue edema. Other colloids used are dextr
Pentastarch is used primarily to treat acute hypovolemia and shock. It is administered IV in acute situations. Pentastarch has a duration of effective volume expansion of 12-48 hours. Pentastarch is used in similar situations as hetastarch, but it is used less frequently.
