    Chloroquine has an extremely high volume of distribution 12,950 L. It also has a high clearance rate of 45 L/hour. This means its half-life is roughly 200 hours! If you have been taking chloroquine and your blood has reached a steady state concentration, it will take over 8 days for the plasma concentration to decrease by 50%. 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. Volume of distribution is not a physical space, but rather an apparent one. Volume of distribution is the apparent volume needed to account for the total amount of drug in the body if the drug was evenly distributed throughout the body and in the same concentration as the site of sample collection such as peripheral venous plasma.

    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.

    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. The CQ pharmacokinetic parameters derived for our nonpregnant women were consistent with those in previous studies of children and adults. All have shown large volumes of distribution 3,500 to 53,000 liters 2, 12, 20, 31, consistent with the median steady-state volume of distribution V SS /F of 6,707 Distribution Chloroquine has a very large volume of distribution and kinetics which fit a two compartment model. The central compartment has a Vd of about 2 L/kg. The major acute toxic syndrome is due to high blood concentrations within this compartment.

    Lupus and Anesthesia - Lupus International Lupus, or SLE, is a chronic, noninfectious, inflammatory disease that affects about 10-15 times as many women as men. The disease is characterized by exacerbations and remissions and the onset of the disease can be slow or sudden. The extent and severity of the symptoms can vary from person to person.
