Volume of Distribution - an overview ScienceDirect Topics
WebThe apparent volume of distribution is the theoretical volume of fluid into which the total drug administered would have to be diluted to produce the concentration in plasma. For example, if 1000 mg of a drug is given and the subsequent plasma concentration is 10 mg/L, that 1000 mg seems to be distributed in 100 L (dose/volume = concentration ... WebJul 11, 2024 · National Center for Biotechnology Information WebAs this example shows, the volume of distribution is a hypothetical volume and not a real volume. + + The volume of distribution gives a rough accounting of where a drug goes in the body, especially if you have a feel for the various body fluid compartments and their sizes (Figure 4–1).
