We know, in actuality, even though, that this is simply not true given that most drugs are certainly not uniformly distributed. Drugs that have relatively little Vd (e.g. 5 L) largely remain in the plasma compartment. Drugs using a Vd of 15L distribute in the course of vascular and extracellular fluid compartments.
