Chloroquine was first discovered in the 1930s in Germany and began to be widely used as an anti-malaria post-World War II, in the late 1940s. However, resistance to the drug also rapidly emerged, with the first cases of not being cured by administration of chloroquine being reported in the 1950s. What areas are chloroquine resustant Plaquenil 200 mg tablets side effects P. falciparum CG2, Linked to Chloroquine Resistance, Does Not Resemble Na+/H+ Exchangers Now, chloroquine resistant forms of P. vivax are found in multiple locations in south-east Asia, such as Myanmar and India, as well as from Guyana in South America. Nowadays, other drugs, and notably ones containing artemisinin-based compounds, are preferentially used to treat uncomplicated malaria and especially in areas where chloroquine resistance is known to occur. Chemosensitizing agents “resistance reversal agents” that can be coadministered with chloroquine may offer another therapeutic approach against chloroquine-resistant P. falciparum. A number of agents of diverse chemical structures and properties selectively enhance the activity of chloroquine against chloroquine-resistant but not chloroquine-sensitive malaria parasites in vitro 37, 67–70. Nowadays, other drugs, and notably ones containing artemisinin-based compounds, are preferentially used to treat uncomplicated malaria and especially in areas where chloroquine resistance is known to occur. Since then, resistance has spread rapidly (since obviously it is beneficial to the parasite to be resistant, so various mutations conferring this protection have arisen multiple times in different areas in the world and also been passed on preferentially to new generations of malaria parasites), and now chloroquine resistant are found in multiple locations in south-east Asia, such as Myanmar and India, as well as from Guyana in South America.

Recombinant clones expressing pfcrt alleles from the chloroquine-resistant lines Dd2, K76I, and 7G8 all had 50% inhibitory concentration IC 50 values in the range of 100 to 150 nM. Chloroquine Resistance in Plasmodium falciparum Malaria.. Chloroquine-Resistant Malaria The Journal of Infectious.. PDF Chloroquine-Resistant Plasmodium Falciparum is it.. These reports of chloroquine-prophylaxis or treatment failures were substantiated by serial parasitologic and clinical observations of each infection and, when available, in-vitro confirmation of drug resistance. CDC continues to monitor the status of chloroquine-resistant P. falciparum malaria in East Africa 2. Malaria caused by Plasmodium falciparum is a severe infectious disease with high mortality and morbidity rates worldwide. Chloroquine CQ is a widely used antimalarial agent, but the emergence and spread of CQ-resistant parasites is a growing The rapid shift in P. falciparum from CQ-resistant to CQ-susceptible suggests that the removal of CQ for the treatment of P. falciparum or the pressure from AL that has been used since 2004 to treat falciparum malaria and mixed infection of P.falciparum and P. vivax or both may eventually lead to replacement of pfmdr1 resistance genes by susceptible parasite populations 42, 57.
