    Drugs that have a volume of distribution 7 4 L or less are thought to be confined to the plasma, or liquid part of the blood. If the volume is between 7 4 and 15 7 L, the drug is thought to be distributed throughout the blood plasma and red blood cells. This is a table of volume of distribution V d for various comparison, those with a V d L/kg body weight of less than 0.2 are mainly distributed in blood plasma, 0.2-0.7 mostly in the extracellular fluid and those with more than 0.7 are distributed throughout total body water. Chloroquine is commonly used to study the role of endosomal acidification in cellular processes 2, 3, such as the signaling of intracellular TLRs. Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation 4.

    Volume of distribution may be increased by kidney failure (due to fluid retention) and liver failure (due to altered body fluid and plasma protein binding). The initial volume of distribution describes blood concentrations prior to attaining the apparent volume of distribution and uses the same formula. In rough terms, drugs with a high lipid solubility (non-polar drugs), low rates of ionization, or low plasma protein binding capabilities have higher volumes of distribution than drugs which are more polar, more highly ionized or exhibit high plasma protein binding in the body's environment.

In contrast to quinine which has a relatively limited apparent volume of distribution approximately 2.51/kg in healthy adults and short elimination half-life 11 hours in healthy subjects, 16 hours in cerebral malaria, chloroquine has an enormous total apparent volume of distribution 100–10001/kg and a terminal elimination half-life of.

    A dose-ranging study of the pharmacokinetics of hydroxy-chloroquine following intravenous administration to healthy volunteers. S E Tett, D J Cutler, R O Day, and K F Brown Department of Pharmacy, University of Sydney, Australia. The drug has an apparent volume of distribution of 116-285 L/kg in healthy adults. Animal studies indicate that concn of chloroquine in liver, spleen, kidney, and lung are at least 200-700 times higher than those in plasma, and concentration of the drug in brain and spinal cord are at least 10-30 times higher than those in plasma. The drug is extensively distributed, with a volume of distribution of 200 to 800 L/kg when calculated from plasma concentrations and 200 L/kg when estimated from whole blood data concentrations being 5 to 10 times higher. Chloroquine is 60% bound to plasma proteins and equally cleared by the kidney and liver.

    Chloroquine - Wikipedia Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication.
