Chloroquine has long been used in the treatment or prevention of malaria from Plasmodium vivax, P. malariae, excluding the malaria parasite Plasmodium falciparum, for it started to develop widespread resistance to it. What is a plaquenil eye exam Aao guidelines for plaquenil Seronegative rheumatoid arthritis and plaquenil Adverse reactions of hydroxychloroquine 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. Chloroquine is the drug of choice for travel to areas where chloroquine resistance has not been described. Chloroquine is active against the erythrocytic forms Fig. 6.3 of sensitive strains of all species of malaria, and it is also gametocidal against P. vivax, P. malariae, and P. ovale. The P. falciparum chloroquine-resistance transporter PfCRT In 2000 a report by David Fidock and colleagues associated chloroquine resistance with mutations to the gene for a digestive vacuole transmembrane protein, pfcrt. PfCRT is a member of the drug/metabolite transporter superfamily. It is recommended to check if chloroquine is still effective in the region prior to using it. Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance.

Since then chloroquine resistant strains have spread throughout the ranges where the conditions are favorable for the development of the parasite especially in the regions of sub-Saharan Africa 6. Chloroquine Resistance in Plasmodium falciparum - microbewiki. Malaria understanding drug resistance - BugBitten. Drug Resistance in the Malaria-Endemic World. Chloroquine phosphate tablets are indicated for the Treatment of uncomplicated malaria due to susceptible strains of P. falciparum, P.malariae, P. ovale, and P.vivax. Prophylaxis of malaria in geographic areas where resistance to Chloroquine is not present. Treatment of extraintestinal amebiasis. Plasmodium falciparum malaria in Haiti is considered chloroquine susceptible, although resistance transporter alleles associated with chloroquine resistance were recently detected. Chloroquine-14C was used to study the processes which concentrate chloroquine in mouse red blood cells infected with chloroquine-sensitive or with chloroquine-resistant Plasmodium berghei. The initial rates of uptake and exchange of chloroquine-14C were both too fast to measure, yet large concentration gradients were maintained by the cells. When red blood cells were exposed to 10-8 M.
