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. Se pueden tomar aspirina y plaquenil juntos Chloroquine cyclosporin Citalopram and hydroxychloroquine Use. Chloroquine is still the drug of choice for sensitive malaria parasites although ACTs are used increasingly. Chloroquine is therefore used widely for P. vivax, P. malariae and P. ovale, but except in a very few areas has been replaced for P. falciparum treatment. The time-honoured oral chloroquine regimen of 25 mg base/kg spread over 3 days 10, 10, 5 or 10, 5, 5, 5 mg/kg at 24-hour intervals can be condensed into 36 hours of drug administration. Heavy use of chloroquine, however, led to the emergence of P. falciparum parasites resistant to chloroquine in Southeast Asia and South America. The resistant parasites that first emerged in Southeast Asia spread to East Africa Tanzania and Kenya by 1980 1, 2 and eventually across the malaria endemic regions of Africa 3. In a recent work, Martin and collaborators were able to express both wild-type and resistant forms of PfCRT on the surface of Xenopus laevis oocytes and clearly demonstrated that chloroquine resistance is due to the direct transport of a protonated form of the drug out of the parasite vacuole via the K76T PfCRT mutant. Interestingly, they also showed that the introduction of the K76T single mutation in PfCRT of CQS parasites is necessary but not sufficient for the transport of chloroquine. 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.

Chloroquine - FDA prescribing information, side effects and uses. On the Mechanism of Chloroquine Resistance in Plasmodium.. Chloroquine resistant Plasmodium vivax review Worldwide.. Verapamil Reversal of Chloroquine Resistance in the Malaria Parasite Plasmodium falciparum Is Specific for Resistant Parasites and Independent of the Weak Base Effect Sep 15, 2001 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. Better understanding of the mechanism of resistance reversal and the role of PfCRT will help in evaluating these agents and perhaps in identifying new candidate compounds for drug development. P. vivax resistance to chloroquine has also now been identified in Southeast Asia, Ethiopia, and Madagascar. Isolated reports have suggested chloroquine-resistance P. vivax in other countries and regions, but further evaluation is needed. Vivax malaria parasites, particularly from Oceania.
