    Chloroquine resistance in the human malaria parasite, Plasmodium falciparum, arises from decreased accumulation of the drug in the `digestive vacuole' of the parasite, an acidic compartment in which chloroquine exerts its primary toxic effect. It has been proposed that changes in the pH of the digestive vacuole might underlie the decreased accumulation of chloroquine by chloroquine-resistant. Chloroquine-resistant Plasmodium falciparum accumulate significantly less chloroquine than susceptible parasites, and this is thought to be the basis of their resistance. However, the reason for the lower accumulation of chloroquine was unknown. The resistant parasite has now been found to release chloroquine 40 to 50 times more rapidly than the susceptible parasite, although their initial. The emergence of Plasmodium falciparum resistance to anti-malarial drugs has thwarted malaria control efforts and remains a major obstacle to malaria elimination throughout the world. Chloroquine was one of the first drugs to be used on a wide scale for the treatment of malaria. Chloroquine resistance emerged independently in different geographic regions.

  3. We obtained 78 human blood samples from areas in Haiti with high transmission of malaria and found no drug resistance–associated mutations in Plasmodium falciparum chloroquine resistance transporter and Kelch 13 genes. We recommend maintaining chloroquine as the first-line drug for malaria in Haiti. Artemisinin-based therapy can be used as alternative therapy.

    Malaria. Chloroquine has long been used in the treatment or prevention of malaria from Plasmodium vivax, P. ovale, and P. malariae, excluding the malaria parasite Plasmodium falciparum, for it started to develop widespread resistance to it. Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. Formerly used as first-line treatment for uncomplicated Plasmodium falciparum malaria in most endemic areas, chloroquine CQ has seen its efficacy reduced in the late 60 s onwards after a decade. Drug-resistant P. falciparum. Chloroquine-resistant P. falciparum first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted.
