    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.

    Drug-resistant P. vivax. Chloroquine-resistant P. vivax malaria was first identified in 1989 among Australians living in or traveling to Papua New Guinea. P. vivax resistance to chloroquine has also now been identified in Southeast Asia, Ethiopia, and Madagascar. Isolated reports have suggested chloroquine-resistance P. vivax in other countries and regions, but further evaluation is needed. 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. 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].

    DRUG RESISTANT MALARIA 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. However, chloroquine resistance was then found to be reversible by verapamil, a drug which also modulates resistance in multidrug resistant MDR mammalian cancer cells. This discovery led to the identification of the protein Pgh1 an analog to overexpressed glycoproteins that expel cytotoxic drugs in cancer cells in the digestive vacuole membrane of P. falciparum. 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.

    Mechanism of action of hydroxychloroquine as an antirheumatic drug. The antimalarial agents chloroquine and hydroxychloroquine have been used widely for the treatment of rheumatoid arthritis and systemic lupus erythematosus. These compounds lead to improvement of clinical and laboratory parameters, but their slow onset of action distinguishes them from glucocorticoids and nonsteroidal antiinflammatory agents.
