Malaria parasites can enter the body through these mosquito bites, and then live in body tissues such as red blood cells or the liver. This medication is used to kill the malaria parasites living inside red blood cells. How to treat plaquenil rash Does plaquenil work for arthritis Chloroquine is an aminoquinoline that is quinoline which is substituted at position 4 by a 5-diethylaminopentan-2-ylamino group at at position 7 by chlorine. It is used for the treatment of malaria, hepatic amoebiasis, lupus erythematosus, light-sensitive skin eruptions, and rheumatoid arthritis. The pharmacokinetics of chloroquine were studied in healthy volunteers who received one of three different multiple-dose regimens for 3 weeks once weekly 300 mg, twice weekly 200 mg and once daily 50 mg chloroquine. Plasma concentrations of chloroquine and metabolites were determined by h.p.l.c. with fluorescence detection. Both adults and children should take one dose of chloroquine per week starting at least 1 week before. traveling to the area where malaria transmission occurs. They should take one dose per week while there, and for 4 consecutive weeks after leaving. The weekly dosage for adults is 300mg base 500mg salt.

Regimens of chloroquine Chloroquine - an overview ScienceDirect Topics, The pharmacokinetics of three multiple dose regimens of. Chloroquine resistant malaria mechanism Recent reports have highlighted that chloroquine CQ is capable of inhibiting ZIKV endocytosis in brain cells. We applied pharmacokinetic modeling to develop a predictive model for CQ exposure to identify an optimal maternal/fetal dosing regimen to prevent ZIKV endocytosis in brain cells. Dose Optimization of Chloroquine by Pharmacokinetic.. Medicines for the Prevention of Malaria While Traveling.. Chloroquine Dosage Guide with Precautions -. Chloroquine is the generic form of the brand-name prescription medicine Aralen, which is used to prevent and treat malaria — a mosquito-borne disease caused by a parasite — and to treat.
