    Pharmacodynamics of chloroquine


    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.

    Chloroquine is a 4-aminoquinoline with antimalarial, anti-inflammatory, and potential chemosensitization and radiosensitization activities. Although the mechanism is not well 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. Patients with longer chloroquine elimination half-life estimates were more likely to report pruritus. Transient, mild to moderate pruritus is a well-known adverse effect of chloroquine and a threat to treatment adherence. Targets-Pharmacodynamics. Antimalarial drugs have a variety of targets and mechanisms of action. Many, like chloroquine, amodiaquine, mefloquine, and quinine act on heme in the parasitic food vacuole. In this way, they prevent the polymerization of hemoglobin, which can be toxic to the plasmodium parasite.

    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.
