    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.

    Although the high volume of distribution tells us that chloroquine distributes into compartments other than 1. - 4, and the concentration in those compartments is probably higher than the concentrations in blood, the GG data do not tell us how low the concentration in blood can be to yield a concentration of 32 microg/ml in Bb cyst infected tissue. Large volume of distribution 50 L/kg; Prolonged half life of several weeks 50% of chloroquine is excreted unchanged; Resuscitation Coma Prompt intubation and ventilation, if acidaemia exists, give sodium bicarbonate 1 – 2 mmol/Kg IV to prevent further toxicity during intubation. End goals should be a narrow QRS 100ms and a pH 7.45 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%.

    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.

  3. The clearance and the central and peripheral volumes of distribution were 15.5 liters/h, 733 liters, and 1,630 liters, respectively. We measured the plasma concentrations of HCQ in patients with prophylactic failure of HCQ and compared them with the prediction intervals of the simulated concentrations for HCQ from the final PK model built in this study.

    Chloroquine is extensively distributed with an enormous total apparent volume of distribution Vd more than 100 L/kg, and a terminal elimination half-life of 1 to 2 months. As a consequence, distribution rather than elimination processes determine the blood concentration profile of chloroquine in patients with acute malaria. 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. If the drug distributes into all body water the volume of distribution would increase to approximately = 0.57 l/kg 5 If the drug readily diffuses into the body fat the volume of distribution may increase dramatically, an example is chloroquine which has a = 250-302 l/kg 6
