    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.

    The initial distribution phase has a half-life of 2-6 days while the terminal elimination phase is 10-60 days. Approximately 50-70% of chloroquine in plasma is bound to the plasma proteins. The principal metabolite is monodesethylchloroquine, which reaches a peak concentration of 10-20 microgram/litre within a few hours.

The average plasma chloroquine concentrations in 5 persons who ingested 3-20 g of the drug was 10 mg/l range 3-16 mg/l; post-mortem specimens{reviewed in 2}. The mean clinically measured acute lethal serum concentration of chloroquine, based on data from several handbooks, was 11 mg/l 3.

    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.

  3. 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.

    Quinine and chloroquine poisoning are characterized by severe cardiovascular toxicity resulting from sodium and potassium channel blockade, leading to hypotension, shock, arrhythmias and cardiac arrest. Quinine poisoning can cause irreversible visual loss. The use of saliva levels as an alternative to plasma levels in monitoring chloroquine therapy was studied in five healthy volunteers. Subjects took two 250mg tablets of chloroquine diphosphate 300mg chloroquine base with 200ml of water. Saliva and blood samples were collected at intervals over 6 days. Plasma was separated from blood samples after centrifugation while saliva samples were. 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.

PLAQUENIL film-coated tablets cannot be divided, therefore they should not be used to treat patients who weigh less than 31 kg.
