    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.

    Since modern drug development, drug concentration assays have almost exclusively used plasma as a matrix rather than whole blood. Various theories about assay sensitivity, matrix interference, protein binding, and free drug movement have been put forth to explain why it is “best” to measure drug concentrations in plasma. 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. WHO Model Prescribing Information Drugs Used in Parasitic Diseases - Second Edition 1995; 152 pages Table of Contents. chloroquine base 150 mg is equivalent to chloroquine sulfate 200 mg or Chloroquine phosphate 250 mg General information. Absorption is efficient following oral administration and peak plasma concentrations occur.

    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.

  4. 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. Chloroquine undergoes appreciable degradation in the body.

    Mean plasma concentrations reached the lower therapeutic window on day 279 with 94% of subjects possessing a trough plasma concentration above the lower therapeutic window and 5% of subjects possessing a peak plasma concentration below the lower therapeutic window Table 5. The peak plasma concentration after an oral dose of chloroquine is 3–12 h 10, 32, 67. Thirty-three to 70 % of the drug in plasma is protein-bound 2, 32, 38, 75, 79, 80. The effects of hypoalbuminemia and altered immunoglobulin composition in patients taking 4AQs are not well understood.

    The Cost and Cost-Effectiveness of Antimalarial Drugs. In one sense, the economics of antimalarial drugs are simple currently effective drugs—those recommended by the global community for most of Africa and Asia—are not affordable by the endemic countries, so few people are getting them. This is in contrast to the previous generation of effective drugs, which were exceedingly cheap by any standards, but which no longer work because drug.
