Today, resistant P. vivax is present in several regions of Southeast Asia, and some evidence suggests that it also occurs in. Chloroquine has long been the drug offered to patients with unconfirmed malaria and those diagnosed with P vivax infection. Given the rise of drug resistance in many infectious agents due to poorly regulated drug use, it is no surprise that resistance has occurred in the organism that so frequently infects us. Chloroquine is the treatment of drug choice for P. vivax infection which kills the asexual stages of the parasite in the blood, along with primaquine that kills the hypnozoite stages of the.

    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].

    Most recently, resistance to the artemisinin and non-artemisinin components of artemisinin-based combination therapy has emerged in parts of Southeast Asia, impacting the efficacy of this vital antimalarial class. Drug-resistant P. vivax. Chloroquine-resistant P. vivax malaria was first identified in 1989 among Australians living in or. Where chloroquine remains the first-line treatment of P vivax, the treatment regimen can potentially be optimised, either by increasing the dose or duration of chloroquine, or by combining chloroquine with an additional drug with blood schizontocidal activity or the ability to reverse chloroquine resistance. 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.
