Resistance to currently available antimalarial drugs has been confirmed in only two of the four human malaria parasite species, 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. Hydroxychloroquine for crest syndrome Hydroxychloroquine with methotrexate Plaquenil hair loss treatment Plaquenil or methotrexate Both adults and children should take one dose of chloroquine per week starting at least 1 week before. traveling to the area where malaria transmission occurs. They should take one dose per week while there, and for 4 consecutive weeks after leaving. The weekly dosage for adults is 300mg base 500mg salt. Chloroquine-sensitive uncomplicated malaria Plasmodium species or species not identified 600 mg base 1 g salt orally at once, followed by 300 mg base 500 mg salt orally at 6, 24, and 48 hours Total dose 1.5 g base 2.5 g salt Chloroquine may make your skin more sensitive to the sun. Avoid unnecessary sun exposure and tanning booths and wear sunscreen and protective clothing when outdoors. Although resistance to these drugs tends to be much less widespread geographically, in some areas of the world, the impact of multi-drug resistant malaria can be extensive. Has also developed resistance to nearly all of the other currently available antimalarial drugs, such as sulfadoxine/pyrimethamine, mefloquine, halofantrine, and quinine.

ANSWER The treatment of malaria in pregnant women has become more challenging in recent years, as many types of malaria are developing resistance to the standard arsenal of drugs. In locations where the dominant form of malaria is still chloroquine-sensitive, chloroquine can be used safely. Jun 15, 2003 Nine of 11 fresh P. falciparum isolates were sensitive to chloroquine in vitro, consistent with a recent report of a high prevalence of in vitro chloroquine-sensitive P. falciparum in central Malawi. The finding that 2 infections yielded microtest values in the intermediate range is most likely explained by inaccuracies of the in vitro test. Of 16 chloroquine-sensitive lines from geographically distant regions, all but 1 showed the “wild-type” PfCRT sequence of the sensitive HB3 parent in the genetic cross. The 1 exception, P. falciparum clone 106/1, carried every mutation associated with chloroquine resistance in Southeast Asia and Africa, except K76T 26 table 1, indicating a critical role for the mutation at position 76.
