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. Hydroxychloroquine ms What helps nausea from plaquenil In infections with P. falciparum or suspected chloroquine-resistant P. vivax, blood smears should be made to confirm adequate parasitologic response to treatment decrease in parasite density. Treatment of Uncomplicated Malaria Summary Chloroquine-resistant malaria from P. falciparum is confirmed in patients from widespread areas throughout Thailand. For adequate treatment of patients and for the successful pursuit of malaria eradication in this area, there is an urgent need for new effective antimalarial drugs. Sep 15, 2001 In P. falciparum the cause of the most lethal human malaria, chloroquine resistance is linked to multiple mutations in PfCRT, a protein that likely functions as a transporter in the parasite’s digestive vacuole membrane. Rapid diagnostic assays for PfCRT mutations are already employed as surveillance tools for drug resistance. 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-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. Chloroquine resistance is widespread. Chloroquine should not be used for treatment of P. falciparum infections from areas of chloroquine resistance or malaria occurring in patients where chloroquine prophylaxis has failed. Patients infected with a resistant strains of plasmodia should be treated with another antimalarial drug. Travelers who reject the advice to take prophylaxis, who choose a suboptimal drug regimen such as chloroquine in an area with chloroquine-resistant P. falciparum, or who require a less-than-optimal drug regimen for medical reasons, are at increased risk for acquiring malaria and then needing prompt treatment while overseas.
