    Chloroquine peak plasma concentraion

    The substances of interest include any chemical xenobiotic such as: pharmaceutical drugs, pesticides, food additives, cosmetics, etc. It attempts to analyze chemical metabolism and to discover the fate of a chemical from the moment that it is administered up to the point at which it is completely eliminated from the body.

    IUPAC definition. 'Pharmacokinetics 1 Process of the uptake of drugs by the body, the biotransformation they undergo, the distribution of the drugs and their metabolites in the tissues, and the elimination of the drugs and their metabolites from the body over a period of time. Chloroquine was detectable in plasma within 30 min of giving the drug. Peak level was reached in 1-8 h after the first dose of 10 mg/kg and the peak concentrations ranged between 65 and 263 ng/ml. Chloroquine concentration declined slowly in plasma after stopping drug administration so that the concentration at the seventh day was 37.5% of the. Chloroquine is deposited in the tissues in considerable amounts. In animals, from 200 to 700 times the plasma concentration may be found in the liver,spleen, kidney, and lung; leukocytes also concentrate the drug. The brain and spinal cord, in contrast, contain only 10 to 30 times the amount present in plasma.

    Both together influence dosing, benefit, and adverse effects, as seen in PK/PD models. Pharmacokinetics is the study of how an organism affects a drug, whereas pharmacodynamics (PD) is the study of how the drug affects the organism.

    • Volume of Distribution - an overview ScienceDirect Topics.

    In humans, chloroquine concentrations decline multiexponentially. 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. Peak plasma concentration is reached 1.5 to 3 hours after ingestion. Distribution by route of exposure Protein binding 5O to 65%. Chloroquine accumulates in high concentrations in kidney, liver, lung and spleen, and is strongly bound in melanin-containing cells eye and skin. Red cell concentration is five to ten times the plasma concentration. For the 300 mg daily dose, the trough plasma concentration doubled, with a shortening of the time taken to reach the target plasma concentration to 5 days. However, the mean steady-state C max was 1.8 ± 0.8 μM with 59% of the subjects demonstrating a peak plasma concentration in excess of 2 μM.
