    In addition, the impact of the patient’s physiopathological status and ethnic origin on chloroquine pharmacokinetics is discussed. 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).

    In several studies in healthy adults, the mean elimination half-life of Mefloquine varied between 2 and 4 weeks, with an average of about 3 weeks. Total clearance, which is essentially hepatic, is in the order of 30 mL/min. There is evidence that Mefloquine is excreted mainly in the bile and feces. Hence, unbound plasma concentrations are higher for R−-chloroquine. Following separate administration of the individual enantiomers, R−-chloroquine reached higher and more sustained blood concentrations. The shorter half-life of S+-chloroquine appears secondary to its faster clearance. In order to determine the pharmacokinetic disposition of chloroquine CQ and its active metabolite, desethylchloroquine DECQ, when administered as intermittent presumptive treatment in pregnancy IPTp for malaria, 30 Papua New Guinean women in the second or third trimester of pregnancy and 30 age-matched nonpregnant women were administered three daily doses of 450 mg CQ 8.5 mg/kg of body.

    Following administration chloroquine is rapidly dealkylated via cytochrome P450 enzymes (CYP) into the pharmacologically active desethylchloroquine and bisdesethylchloroquine. Chloroquine is 60% bound to plasma proteins and equally cleared by the kidney and liver.

    Hydroxychloroquine HCQ, sold under the brand name Plaquenil among others, is a medication used for the prevention and treatment of certain types of malaria. Specifically it is used for chloroquine-sensitive malaria. Other uses include treatment of rheumatoid arthritis, lupus, and porphyria cutanea tarda. It is taken by mouth. It is also being used as an experimental treatment for SARS-CoV-2. The elimination half-life t 1/2, clearance CL. Chloroquine CQ was introduced 50 years ago as an alternative to quinine 25, 70. It became the drug of choice for both prophylaxis and treatment of malaria, but resistance has caused a decline in the contemporary clinical use of chloroquine 25, 35, 40, 70, 72. The plasma half-life of chloroquine in healthy individuals is generally reported to be 72-120 hr. In one study, serum concentrations of chloroquine appeared to decline in a biphasic manner and the serum half-life of the terminal phase increased with higher dosage of the drug.
