Chloroquine was first discovered in the 1930s in Germany and began to be widely used as an anti-malaria post-World War II, in the late 1940s. However, resistance to the drug also rapidly emerged, with the first cases of not being cured by administration of chloroquine being reported in the 1950s.

Guinea-Bissau, routinely used triple standard-dose chloroquine remained effective for decades despite the existence of "chloroquine-resistant" P. falciparum. This study aimed to determine the in vivo efficacy of higher chloroquine concentrations. Since Moore And Lanier's 1 report of two patients with chloroquine-resistant Plasmodium falciparum infections acquired in the Magdalena Valley of Columbia in 1961, a fear has existed among malariologists that large-scale outbreaks of resistant malignant tertian malaria might develop. This fear was increased considerably by the discovery of strains of chloroquine-resistant P. falciparum in. Haiti is a unique country in the Americas because malaria is caused there mainly by Plasmodium falciparum. Despite chloroquine being used for treatment of malaria since 1955, P. falciparum is generally still susceptible to this drug. Nowadays, other drugs, and notably ones containing artemisinin-based compounds, are preferentially used to treat uncomplicated malaria and especially in areas where chloroquine resistance is known to occur. Since then, resistance has spread rapidly (since obviously it is beneficial to the parasite to be resistant, so various mutations conferring this protection have arisen multiple times in different areas in the world and also been passed on preferentially to new generations of malaria parasites), and now chloroquine resistant are found in multiple locations in south-east Asia, such as Myanmar and India, as well as from Guyana in South America. Chloroquine resistant plasmodium falciparum treatment Malaria, treatment Treatment summary BNF content published by NICE, Treatment of Chloroquine-resistant Plasmodium falciparum. Chloroquine and proguanil dose 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. No Plasmodium falciparum Chloroquine Resistance.. No Plasmodium falciparum Chloroquine Resistance Transporter.. Chloroquine Resistance in Plasmodium falciparum Malaria Parasites.. The spread of resistant P. falciparum to previous first-line treatment of malaria chloroquine and sulfadoxine-pyrimethamine in nearly all endemic countries originated in almost similar fashion 8. In the treatment of chloroquine-resistant, P. falciparum malaria in Sudan, once-daily treatment with quinine, in a relatively low daily dose 15 mg/kg. day, appears as effective as the thrice. Emerging resistance to chloroquine CQ by Plasmodium vivax threatens the health of the hundreds of millions of people routinely exposed to the risk of infection with this organism. CQ has been the first-line therapy for vivax malaria since 1946 32, 115.
