    Volume of distribution of chloroquine


    Conceptual illustration of effect of drug distribution into tissue space on V: Consider 100 mg of a drug is added to 1 L of water in a beaker under two circumstances and the liquid is sampled for drug concentration (C). , also known as apparent volume of distribution) is the theoretical volume that would be necessary to contain the total amount of an administered drug at the same concentration that it is observed in the blood plasma.) is possible, and would indicate that the drug is highly distributed into tissue.

    The volume of distribution for chloroquine is so large because this lipophilic drug log P = 4.7 partitions into tissue fat; whereas digoxin log P = 0.85 large volume is attributed to its binding to muscle ATPases. Chloroquine diphosphate 3 mg base kg‐1 was given by constant rate intravenous injection over 10 min to 12 healthy adult male volunteers. Plasma concentrations of chloroquine and the principal met. Water Soluble drugs have low Vd. Eg. Gentamycin vd = 110 ml/kg 5. Lipid soluble drugs have high Vd Eg. Thiopental vd = 2300 ml/kg 6. Pathological condition. In edematous condition, water soluble drugs have high volume of distribution  8. Tissue binding. High Vd with higher tissue binding Eg.

    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.

    Warfarin distributes into a comparatively small apparent volume of distribution of approximately 0.14 L/kg. After speedy intravenous and oral administration of an aqueous solution, a distribution phase enduring 6 to 12 hours is separated. By using one compartment model, and supposing complete bioavailability. 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. It is defined as the volume in which the amount of drug would need to be uniformly distributed to produce the observed blood concentration. Volume of distribution may be increased by renal failure due to fluid retention and liver failure due to altered body fluid and plasma protein binding.

    Supercoiling in prokaryotic and eukaryotic DNA changes in. Chloroquine, a DNA intercalating drug, unwinds the DNA, decreasing the levels of negative supercoiling. Following this in vivo topological perturbation, within minutes DNA gyrase decreases DNA linking number producing more negatively supercoiled DNA topoisomers. Following the removal of the drug from cells.
