    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.

    An analog of chloroquine – hydroxychloroquine – has a long half-life 32–56 days in blood and a large volume of distribution 580–815 L/kg. The therapeutic, toxic and lethal ranges are usually considered to be 0.03 to 15 mg/l, 3.0 to 26 mg/l and 20 to 104 mg/l, respectively. Volume of distribution is a pharmacokinetic concept which is used to describe the distribution of drugs in the body as relative to the measured concentration. In brief, it is the apparent volume into which the drug appears to be distributed when only the sample concentration is considered. It is a purely theoretical volume, which can substantially exceed the total body volume, or potentially. 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. If the volume of distribution is larger than 42, the drug is thought to be distributed to all tissues in the body, especially the fatty tissue.

    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.

  6. Further dividing this by the patient's weight gives us an apparent volume of distribution for Drug B of 0.29 litres per kilogram. The difference between the apparent volumes of distribution of these two drugs is due to their differing lipid vs water solubilities and plasma protein vs tissue binding characteristics.

    In our studies, a total of 431 plasma samples were prepared from 22 healthy subjects and 69 patients with vivax malaria for three different studies studies Ia, Ib, and II. In study Ia, a single dose of HCQ sulfate of 400 mg 310 mg as HCQ was administered to six healthy South Korean male volunteers and serial. 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. Dec 23, 2012 It therefore easily traverses other tissues and has a large volume of distribution 2100 L. Chloroquine is even more hydrophobic and has one of the highest volumes of distribution of any approved drug 12950 L! This means that, if you take chloroquine, most of the drug is found not in the blood but in tissues like fat.
