    Tell your doctor and pharmacist about all of your drugs (prescription or OTC, natural products, vitamins) and health problems. You must check to make sure that it is safe for you to take chloroquine with all of your drugs and health problems.

    Antiprotozoal-Malaria /Mechanism of action/ may be based on ability of chloroquine to bind and alter the properties of DNA. Chloroquine also is taken up into the acidic food vacuoles of the parasite in the erythrocyte. It increases the pH of the acid vesicles, interfering with vesicle functions and possibly inhibiting phospholipid metabolism. Thus, it has been found that chloroquine’s action is limited to the stages of parasites life cycle that are actively degrading hemoglobin. Although the molecular basis of chloroquine action is yet to be properly elucidated, some progress has been made in understanding its mechanism in the body. The mechanisms of action of hydroxychloroquine and chloroquine remain under continuous study in modern molecular medicine 17,18 using advanced tools in computational biology 19, synthetic biology.

    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. Do not start, stop, or change the dose of any drug without checking with your doctor.

This finding, obtained without making any assumption on the nature of PfCRT, implies that hypothesis H2 is plausible, regardless of the chloroquine species involved in the chloroquineHM binding and of the mechanism of action of the mutated PfCRT. Consequently, none of the 20 cells C 1–5,1–4 can be shaded at this stage.

    • Antimalarial Drug Mechanism of Action What is Chloroquine?.

    Chloroquine is the most widely used drug against malaria, except for those cases caused by chloroquine resistant Plasmodium falciparum. Although the mechanism of action is not fully understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin, thereby resulting in the accumulation of toxic heme within the parasite. 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. 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 enzymes by its interaction with DNA.
