Presenter Dr. Tanmay Mehta MD, DNB, PGDCTM 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. 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.

    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. Chloroquine mechanism of drug action and resistance in Plasmodium falciparum. Slater AF1. Author information 1Picower Institute for Medical Research, Manhasset, NY 11030. Quinoline-containing drugs such as chloroquine and quinine have had a long and successful history in antimalarial chemotherapy. The mechanisms of chloroquine accumulation in the food vacuole have been proposed to be accumulation of chloroquine in the food vacuole as a result of increased acidity, presence of a carrier in the parasite and the presence of a receptor in the vacuole that chloroquine can bind to 10.
