    Rapid diagnostic assays for Pf CRT mutations are already employed as surveillance tools for drug resistance. Here, we review recent field studies that support the central role of Pf CRT mutations in chloroquine resistance.

    Chloroquine CQ was the cornerstone of anti-malarial treatment in Africa for almost 50 years, but has been widely withdrawn due to the emergence and spread of resistance. Recent reports have suggested that CQ-susceptibility may return following the cessation of CQ usage. Here, we monitor CQ sensitivity and determine the prevalence of genetic polymorphisms in the CQ resistance transporter. Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. Chloroquine dose for the treatment of uncomplicated Malaria 1000 mg 600 mg base on day 1, followed by 500 mg 300 mg base at 6, 24, and 48 hours after the first dose. Concomitant therapy with primaquine in patients with chloroquine-sensitive P.vivax and P.ovale is necessary.

    Recognition of the value of chloroquine was delayed, and it was not brought forward until it was reevaluated in the United States and designated the drug of choice against malaria near the end of World War II [3]. These studies suggest chloroquine resistance arose in ⩾4 distinct geographic foci and substantiate an important role of immunity in the outcomes of resistant infections after chloroquine treatment. Investigation of the resistance mechanisms and of the role of immunity in therapeutic outcomes will support new approaches to drugs that can take the place of chloroquine or augment its efficiency Early in the 20th century, intense demands for an effective quinine substitute launched the discovery and evaluation of a series of organic compounds (beginning with methylene blue), which led to pamaquine and quinacrine after World War I and ultimately produced chloroquine in 1934 [1, 2].

    Chloroquine is a 4-aminoquinoline with antimalarial, anti-inflammatory, and potential chemosensitization and radiosensitization activities. Although the mechanism is not well 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. An alternative to chloroquine for primary prophylaxis* only in areas with chloroquine- sensitive P. falciparum - Begin 1-2 weeks before travel to endemic areas. Take weekly on the same day of the week while in the endemic areas and for 4 weeks after leaving such areas. Sep 15, 2001 This is a striking demonstration of natural selection on microorganisms under drug pressure. Chloroquine, used at recorded levels 190 tons hundreds of millions of treatment courses in Africa alone each year, has been a tremendous force driving the widespread replacement of chloroquine-sensitive by chloroquine-resistant P. falciparum.
