    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. A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen. 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.

    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/hydroxychloroquine is extruded to the extracellular medium mostly by exocytosis and/or through the action of the multidrug resistance protein MRP-1, a cell surface drug transporter belonging to the ATP-binding cassette family, which also includes the more thoroughly studied P-glycoprotein. In this video, I will explain into one of the main antimalarial drug, chloroquine. Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive.
