Previously referred to as “Resochin”, Chloroquine was first discovered in 1924 at Bayer laboratories. Its first use was initially ignored as it was found to be toxic to people. What happens when you take antiacid with plaquenil Can i take mucinex d with plaquenil Plaquenil heat Intensified treatment and control efforts since the early 2000s have dramatically reduced the burden of Plasmodium falciparum malaria. However, drug resistance threatens to derail this progress. However, drug resistance threatens to derail this progress. Resistance to chloroquine, in the case of P. falciparum, is linked to mutations in the P. falciparum chloroquine resistance transporter pfcrt gene, which alters the transport and accumulation of the drug in the digestive vacuole DV of the parasite 7, 8. Oct 04, 2002 Plasmodium falciparum chloroquine resistance is a major cause of worldwide increases in malaria mortality and morbidity. Recent laboratory and clinical studies have associated chloroquine resistance with point mutations in the gene pfcrt. However, direct proof of a causal relationship has remained elusive and most models have posited a. These trials showed that chloroquine eliminated malaria and was appropriate to be used as an antimalarial drug. Thus, it was not until World War II that the government of the United States sponsored the clinical trials of chloroquine as an antimalarial drug. Chloroquine: mechanism of drug action and resistance in plasmodium falciparum The mechanisms of resistance to antimalarial drugs in., Antiplasmodial activity of chloroquine analogs against. Concordia pharmaceuticals plaquenil Resistance to chloroquine has, however, steadily spread since the 1960s from two foci, one in South America and one in South East Asia. Throughout the 1980s, chloroquine resistance spread through Africa, the global heartland of malaria mortality and morbidity, and there are very few effective and affordable drugs to take its place. Malaria Dissecting chloroquine resistance Current Biology. Chloroquine Resistance in Plasmodium falciparum Malaria.. Plasmodium Chloroquine Resistance and the Search for a..

Microbiol. 97, 381–395 2015. Drug transport is believed to be of crucial importance for understanding the mechanisms of chloroquine resistance, as it is clear that less chloroquine accumulates in chloroquine-resistant parasites than in chloroquine-sensitive parasites. It was originally thought that this lack of accumulation was the result of an efflux mechanism, and a P-glycoprotein was implicated as the pump responsible for the efflux.
