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. Chloroquine phosphate testing kit Plaquenil drug interactions side effects Concurrent administration of chloroquine Volume of distribution V d is a theoretic concept that relates the amount of drug in the body dose to the concentration C of drug that is measured in blood, plasma, and unbound in tissue water. Volume of distribution is the volume of fluid “apparently” required to contain the total-body amount of drug homogeneously at a concentration equal to that in plasma or blood Fig. 7-2 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. 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. 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.

Plasma concentration profiles after parenteral administration were characterized by wide fluctuations between peak and trough values. Absorption of im and sc chloroquine was rapid, with a median time to peak concentration of 30 min and a peak plasma concentration five times higher than after oral administration.
