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. Describe eye tests for plaquenil Acid reflux and plaquenil Prophylaxis for international travel to chloroquine resistant area 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. 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. The term “chloroquine resistance” can lead to misunderstandings when it is considered by some to refer to in vitro phenotypes, by others to refer to the ability of malaria parasites to survive chloroquine at therapeutic serum concentrations in vivo, and yet by others to refer to the outcome of a clinical episode after chloroquine therapy. 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 . 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 is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. It is also occasionally used for amebiasis that is occurring outside the intestines, rheumatoid arthritis, and lupus erythematosus. It is taken by mouth. Common side effects include muscle problems, loss of appetite, diarrhea, and skin rash. Serious Background. The spread of resistance to chloroquine CQ led to its withdrawal from use in most countries in sub-Saharan Africa in the 1990s. In Malawi, this withdrawal was followed by a rapid reduction in the frequency of resistance to the point where the drug is now considered to be effective once again, just nine years after its withdrawal. Chloroquine is a member of an important series of chemically related anti-malarial agents, the quinolone derivatives.
