    The resistance of P falciparum to chloroquine has increased and spread widely since it was first reported from South-East Asia and South America about 30 years ago.

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.

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].

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. Chloroquine is a 4-aminoquinoline which has marked, rapid schizontocidal activity against blood forms of P. ovale and P. malariae and against susceptible strains of P. vivax and P. falciparum. It is also gametocytocidal against P. vivax, P. ovale and P. malariae and immature P. falciparum. It is not active against intrahepatic forms.
