    Chloroquine resistant malaria mechanism

    With concentrated malaria eradication efforts currently underway, monitoring drug resistance in clinical settings complemented by in vitro drug susceptibility assays and analysis of resistance markers, becomes critical to the implementation of an effective antimalarial drug policy. Understanding of the factors, which lead to the development and spread of drug resistance, is necessary to design optimal prevention and treatment strategies.

    As drug resistance is genetically determined, it will spread by active malaria transmission, as gametocytes from resistant isolates will produce resistant offspring. Many African countries switched their fi rst-line drug to sulfadoxine- pyrimethamine SP; however, resistance to SP has grown and spread very quickly, especially in Southeast Asia, South America 4, 7 and more recently in many areas of Africa 8. Oct 01, 2018 Prophylaxis of malaria in geographic areas where resistance to Chloroquine is not present. Treatment of extraintestinal amebiasis. Chloroquine phosphate tablets do not prevent relapses in patients with vivax or ovale malaria because it is not effective against exoerythrocytic forms of the parasites. The emergence and spread of chloroquine-resistant Plasmodium falciparum malaria parasites has been a disaster for world health. Resistance is conferred by mutations in the Chloroquine Resistance.

    The development of resistance to drugs poses one of the greatest threats to malaria control and results in increased malaria morbidity and mortality. This review attempts to summarize the unique factors presented by malarial parasites that lead to the emergence and spread of drug resistance, and gives an overview of known resistance mechanisms to currently used antimalarial drugs.

    Chloroquine has been the standard of care for P. falciparum malaria for more than 40 years but the spread of resistant parasites in all malaria endemic regions has led to abandonment of the drug. The drug, chloroquine, is a medication used to prevent and to treat malaria, as well as a type of liver infection. It was first used to treat malaria in 1944. Proposed mechanism of chloroquine mechanism of action in the parasite’s food vacuole. Asexual malaria parasites flourish in host erythrocytes by digesting hemoglobin in their acidic food vacuoles, a process that generates amino acids, free radicals and heme ferriprotoporphyrin IX, the later two being highly reactive by-products.

    Chloroquine phosphate C18H32ClN3O8P2 - PubChem Chloroquine is the most widely used drug against malaria, except for those cases caused by chloroquine resistant Plasmodium falciparum. Although the mechanism of action is not fully understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin, thereby resulting in the accumulation of toxic heme within the parasite.
