Chloroquine is the prototype anti malarial drug, most widely used to treat all types of malarial infections. It is also the cheapest, time tested and safe anti malarial agent. Mechanism of action The mechanism of action of chloroquine is unclear. Being alkaline, the drug reaches high concentration within the food vacuoles of the. 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. Chloroquine is thought to exert its antimalarial effect by preventing the polymerization of toxic heme released during proteolysis of hemoglobin in the Plasmodium digestive vacuole. The mechanism of this blockade has not been established. For all uses of chloroquine: WARNING/CAUTION: Even though it may be rare, some people may have very bad and sometimes deadly side effects when taking a drug.

By 1946, Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. Occasionally it is used for amebiasis that is occurring outside the intestines, rheumatoid arthritis, and lupus erythematosus. Chloroquine acts exclusively in the erythrocyte stage of malaria parasites. The antimalarial mechanism of action from chloroquine has not been fully elucidated. Many theories have been developed to elucidate the chloroquine mechanism of action, including DNA binding and inhibition of various enzymes and/or transporters.
