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. Ophthalmologist for plaquenil Chloroquine resistance definition It conserves hemoglobin, converting heme rapidly into insoluble and ineffective pigment known as ferri proto porphyrin 9 or Hemozoin, which is non-lethal and non-toxic to plasmodium speices. It has high affinity for chloroquine, which is another mechanism for trapping chloroquine. Once trapped, chloroquine acts by one of many ways a. Count__/__total__ Changes to YouTube’s Terms of Service The clinical usefulness of chloroquine, and in some recent cases of quinine as well, has been much reduced by the evolution and spread of chloroquine resistant malaria parasites. The mechanism of resistance involves a reduced accumulation of the drug, although again the mechanism involved is controversial. 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.
