  1. History of chloroquine resistance


    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.

    Emergence of resistance to antimalarial drugs has become a major hurdle in the successful treatment of the infection, and has contributed significantly to global malaria-related mortality.1 Till date, drug resistance has been documented in P. falciparum, P. vivax, and P. malariae.1 Hydroxychloroquine and chloroquine are medications traditionally prescribed to prevent or treat malaria infections. In certain countries and parts of the world where malaria is still present, a person can easily catch malaria from a seemingly insignificant mosquito bite. Chloroquine is an antimalarial drug. Doctors can usually cure people who are infected with the malaria parasite with various drugs, including this one, but sometimes the parasite is immune to a certain drug. In the case of chloroquine resistance, the parasite appears to have evolved in a way that prevents the drug from getting into the parasite.

    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].

For prevention and treatment of malaria in infants and children, the amount of chloroquine phosphate is based on the child's weight.
