    Artemisinin and other artemether-group drugs have been the main line of defense against drug resistant malaria in many parts of South-East Asia. Artemisinin has been a very potent and effective antimalarial drug, especially when used in combination with other malaria medicines. 3 Combining an artemisinin drug with a partner drug that has a. The clinical usefulness of chloroquine, and in some recent cases of quinine as well, has been much reduced by the evolution and spread of chloroquine resistant malaria parasites. The mechanism of resistance involves a reduced accumulation of the drug, although again the mechanism involved is controversial. Antimalarial drug resistance Antimalarial drug resistance is not new. In the 1970s and 1980s, Plasmodium falciparum – the parasite species responsible for the most common and most deadly form of malaria – developed widespread resistance to previous antimalarial medicines, such as chloroquine and sulfadoxine-pyrimethamine SP.

    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].

    Jan 10, 2020 Chloroquine was first discovered in 1934 and for decades was widely used as a cheap and safe drug both to treat malaria, and as a prophylaxis. However, in the 1980s, widespread resistance developed in the parasite causing the most pathogenic form of malaria, Plasmodium falciparum. Responding to antimalarial drug resistance. Resistance to antimalarial medicines is a threat to global efforts to control and eliminate malaria. Improved access to effective malaria treatments has been a key contributing factor to the significant reduction in the malaria burden in recent years. There is a tendency to view the development of antimalarial-drug resistance as an inevitable outcome of the drugs' widespread use. 90% of falciparum malaria cases were resistant to chloroquine.
