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).

An interval of at least two hours between intake of ampicillin and Chloroquine should be observed. Jan 19, 2010 The efficacy of one of these, chloroquine CQ, has been compromised by the widespread development of Plasmodium falciparum resistance. However, due to a lack of suitable alternatives, CQ is still widely used in pregnant women, either alone or in combination with other drugs such as sulfadoxine-pyrimethamine SP. 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. 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.

A quinolone antibiotic is a member of a large group of broad-spectrum bacteriocidals that share a bicyclic core structure related to the substance 4-quinolone. They are used in human and veterinary medicine to treat bacterial infections, as well as in animal husbandry. Nearly all quinolone antibiotics in use are fluoroquinolones, which contain a fluorine atom in their chemical structure and. Chemically the drug is 2- 4- 7-Chloro-4-quinolyl amino pentyl ethylamino ethanol sulfate 11. Its structural formula is The molecular weight of hydroxychloroquine sulfate is 433.95, and molecular formula is C 18 H 26 ClN 3 O. H 2 SO 4. Ampicillin In a study of healthy volunteers, chloroquine significantly reduced the bioavailability of ampicillin. An interval of at least two hours between intake of ampicillin and chloroquine should be observed. Cyclosporine After introduction of chloroquine oral form, a sudden increase in serum cyclosporine level has been reported.
