Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it. Chloroquine and primaquine side effects Can plaquenil make your mouth and throat dry Drug-resistant P. falciparum. Chloroquine-resistant P. falciparum first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted.

Since the discovery of Plasmodium falciparum chloroquine CQ resistance transporter PfCRT and its role as the primary genetic determinant of chloroquine resistance CQR in P. falciparum, 53 distinct isoforms of this 424 amino acid protein have been found to be expressed in parasite isolates from around the globe 1–4. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead. Plasmodium falciparum resistance to chloroquine On the Mechanism of Chloroquine Resistance in Plasmodium falciparum, CRT - Chloroquine resistance transporter - Plasmodium falciparum - CRT.

P. falciparum and P. vivax have been confirmed to be resistant in some areas to many antimalarial drugs. For example, chloroquine resistant strain of P. falciparum has spread to most endemic areas. Plasmodium Falciparum - Malaria. Plasmodium falciparum chloroquine resistance transporter PfCRT.. Return of chloroquine-sensitive Plasmodium falciparum parasites and.. Chloroquine resistance in the human malaria parasite, Plasmodium falciparum, arises from decreased accumulation of the drug in the `digestive vacuole' of the parasite, an acidic compartment in which chloroquine exerts its primary toxic effect. It has been proposed that changes in the pH of the digestive vacuole might underlie the decreased accumulation of chloroquine by chloroquine-resistant. Chloroquine mechanism of drug action and resistance in Plasmodium falciparum. Slater AF1. Author information 1Picower Institute for Medical Research, Manhasset, NY 11030. Quinoline-containing drugs such as chloroquine and quinine have had a long and successful history in antimalarial chemotherapy.
