    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).

    Ampicillin In a study of healthy volunteers, chloroquine significantly reduced the bioavailability of ampicillin. An interval of at least two hours between intake of this agent and chloroquine should be observed. Cyclosporine After introduction of chloroquine oral form, a sudden increase in serum cyclosporine level has been reported. Mary F. Hebert, in Clinical Pharmacology During Pregnancy, 2013. 3.2.10 Volume of distribution. Volume of distribution is not a physical space, but rather an apparent one. Volume of distribution is the apparent volume needed to account for the total amount of drug in the body if the drug was evenly distributed throughout the body and in the same concentration as the site of sample collection. Chloroquine is widely available in India, and is manufactured by several local companies including Ipca Laboratories, Alembic Pharmaceutricals and Cadila Pharmaceuticals. “Together with ritonavir, which increases drug bioavailability, it is in clinical trials, along with the immunomodulator interferon beta-1b, for the treatment of Middle.

    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.

Both HCQ and CQ have prolonged half-lives, between 40 and 50 days, and low blood clearance e.g. hydroxychloroquine's blood clearance is 96 ml/min.

    Five healthy volunteers received, in a randomised crossover design study, a 155 mg oral tablet and an intravenous infusion of 155 mg racemic hydroxychloroquine 200 mg hydroxychloroquine sulphate to assess the bioavailability of the commercially available tablet Plaquenil, Winthrop Laboratories, Australia. Desethylchloroquine and bisdesethylchloroquine concentrations reach 40 and 10% of chloroquine concentrations, respectively; both chloroquine and desethylchloroquine concentrations decline slowly, with elimination half-lives of 20 to 60 days. Bioavailability of chloroquine is greater when administered with food; a rate of absorption is unaffected but peak plasma concentrations and AUCs are higher. a. Distribution Extent.
