Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it. Changes in taste and smell caused by hydroxychloroquine Chloroquine elimination route Hydroxychloroquine dosage aao Dmards plaquenil However, drug resistance threatens to derail this progress. In this review, we present four antimalarial resistance case studies that differ in timeline, technical approaches, mechanisms of action, and categories of resistance chloroquine, sulfadoxine-pyrimethamine, artemisinin, and piperaquine. Chloroquine Phosphate is the phosphate salt of chloroquine, a quinoline compound with antimalarial and anti-inflammatory properties. Chloroquine is the most widely used drug against malaria, except for those cases caused by chloroquine resistant Plasmodium falciparum. Chloroquine mechanism of drug action and resistance in Plasmodium falciparum. Slater AF1. Author information 1Picower Institute for Medical Research, Manhasset, NY 11030. Quinoline-containing drugs such as chloroquine and quinine have had a long and successful history in antimalarial chemotherapy. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

The precise mechanism by which Chloroquine exhibits activity is not known. Chloroquine, may exert its effect against Plasmodium species by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme. It can also inhibit certain enzymes by its interaction with DNA. Chloroquine - Prescription Drug Information.. Chloroquine mechanism of drug action and resistance in.. Chloroquine Mechanism of drug action and resistance in.. CHLOROQUINE SENSITMTY IS CONFINED TO PARASITE STAGES V~I-IICH DEGRADE HEMOGLOBIN Early clinical investigations of the antimalarial activities of chloroquine, quinacrine and the cinchona alkaloids noted that drug action in each case was limited to those stages of the parasite Chloroquine in Plasmodium falciparum 209 life cycle which were actively degrading hemoglobin refer to Fig. 2 for a diagrammatic representation of the intraerythrocytic development cycle of malaria parasites. We believe that our results, besides shedding light on the mechanism of chloroquine resistance in P. falciparum, have implications for the development of novel therapies against resistant malaria strains and demonstrate the usefulness of an approach combining systems biology strategies with structural bioinformatics and experimental data. Studies in several West African countries, as well as a recent assessment of drug susceptibility of P. falciparum infections in western and central Zaire, have failed to demonstrate chloroquine-resistance 5.
