A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.
Plasma expanders are agents that have relatively high molecular weight and boost the plasma volume by increasing the osmotic pressure. They are used to treat patients who have suffered hemorrhage or shock. Shock occurs due to reduced blood volume (usually due to hemorrhage) and it is necessary to get the blood volume back to normal as quickly as possible.
