    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.

    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. 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. Plasma volumes of distribution up to 65,000 L for chloroquine and 44,257 L for hydroxychloroquine have been reported 71, 75, 77. Normalized by body mass, reported volumes of distribution for chloroquine have ranged from 204 to 800 L/kg depending on the sensitivity of the method of detecting chloroquine.

    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 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.

    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. Results following a single dose of a 200 mg tablet versus i.v. infusion 155 mg, demonstrated a half-life of about 40 days and a large volume of distribution. Peak blood concentrations of. For example, if 1000 mg of a drug is given and the subsequent plasma concentration is 10 mg/L, that 1000 mg seems to be distributed in 100 L dose/volume = concentration; 1000 mg/ x L = 10 mg/L; therefore, x= 1000 mg/10 mg/L = 100 L.

    If you are allergic to sulfa drugs does this mean you can. I have been allergic to sulfa meds for over 30 years. I have been taking plaquenil for about 8 years with no problems. However, I was givin the generic Plaquenil at first, and I did have a reaction to that - until now I didn't reliese was the same as my sulfa reaction.
