Volume of distribution (Vd) (definition) The volume necessary to hold all of the drug in the body at the same concentration which it is at in the blood/plasma. Not a real, physiological volume. High Vd indicates that the drug is widely distributed to extravascular tissues. Low Vd indicates that the drug is retained in the vascular compartment.
