    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.

    Before using chloroquine for prophylaxis, it should be ascertained whether chloroquine is appropriate for use in the region to be visited by the traveler. Chloroquine should not be used for treatment of P. falciparum infections acquired in areas of chloroquine resistance or malaria occurring in patients where chloroquine prophylaxis has failed. P. falciparum has developed resistance to nearly all antimalarial drugs currently in use; P. vivax has been found to be resistant to chloroquine and primaquine; and P. Malariae has been reported to be resistant to chloroquine and pyrimethamine in some areas.1-3 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.

    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 resistance Chloroquine is ineffective in almost all malaria endemic countries In India chloroquine resistance was first detected in 1973 in Assam. Severe in northeast and southeastern regions of India with high morbidity and mortality. Opment of resistance to antimalarial drugs. To date, drug resistance has only been documented in two of the four species, P. falciparum and P. vivax. 2.3 Diagnosis Table 1 Direct microscopic examination of intracellular parasites on stained blood films is the current stand-ard for definitive diagnosis in nearly all settings. P. falciparum or Species Not Identified – Acquired in Areas Without Chloroquine Resistance. For P. falciparum infections acquired in areas without chloroquine-resistant strains, which include Central America west of the Panama Canal, Haiti, and the Dominican Republic, patients can be treated with oral chloroquine.
