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. Plaquenil and parkinsons Plaquenil reduce immune system Can plaquenil cause eye dryness Mechanism of Action Chloroquine, a 4-aminoquinoline, is an anti-protozoal agent. The precise mechanism by which Chloroquine exhibits activity is not known. Chloroquine, may exert its effect against Plasmodium species by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme. It can also inhibit certain. 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. We incubated cultured parasites with subinhibitory doses of 3Hchloroquine and 3H quinidine. These 3Hquinoline compounds became associated with hemozoin. It is a prototypical antimalarial agent with a mechanism that is not well understood. It has also been used to treat rheumatoid arthritis, systemic lupus erythematosus, and in the systemic therapy of amebic liver abscesses. PubChemThe mechanism of plasmodicidal action of chloroquine is not completely certain. 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 parasites accumulate less chloroquine in the food vacuole than do sensitive parasites Fitch, 1970 and one assumption is that chloroquine resistance is not based on the mode of action of the drug but on the access of the drug to the parasite food vacuole. Mechanism of action The precise mechanism by which hydroxychloroquine exhibits activity against. Plasmodium. is not known. Hydroxychloroquine, like chloroquine, is a weak base and may exert its effect by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme.
