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. Is weight gain a side effect of plaquenil Do joints hurt more when starting plaquenil Plaquenil overdose Plaquenil and ace inhibitor Mefloquine• Quinoline methanol derivative developed to deal with chloroquine resistant malaria• Rapidly acting erythrocytic schizonticide, slower than chloroquine & quinine• Effective against chloroquine sensitive & resistant plasmodia• Mechanism of action similar to chloroquine 32. Mechanism of action Chloroquine basic concentrates in parasite food vacuole acidic. Prevent heme polymerization into hemozoin causing heme accumulation toxic to parasite. Drug complex with heme disrupt cell membrane function. Other mechanism include intercalating of parasite DNA, DNA synthesis inhibition. 7. Effects of chloroquine? Chloroquine is a relatively well-tolerated. medicine. The most common adverse reactions reported are stomach pain, nausea, vomiting, and headache. These side effects can often be lessened by taking chloroquine with food. Chloroquine may also cause itching in some people. All medicines may have some side effects. 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.

As it is basic drug it Increases pH of the vacules in the parasite, so prevent its utilization of erythrocyte hemoglobin. OTHER USES Amebic liver abscess as chloroquine is concentrated in the liver. Learn about Chloroquine Mechanism of action and resistance in 2 minutes. Presenter Dr. Tanmay Mehta MD, DNB, PGDCTM Their mechanisms of action are unclear, though they appear to work by enhancing chloroquine uptake by the parasite. Interestingly, studies with verapamil suggest that, although it enhances chloroquine uptake in resistant strains, chloroquine levels still do not reach those found in sensitive strains.
