Chloroquine Its Mechanism of Action Upon Immune Phenomena. Data were presented to indicate that the antimalarial drug chloroquine does not interfere with the normal antibody response in rabbits nor does it depress the levels of formed antibody. Chloroquine Mechanism of action i. The parasite digests the host cell’s hemoglobin to obtain essential amino acids ii. The process releases large amounts of heme, which is toxic to the parasite iii. To protect itself the parasite ordinarily polymerizes the heme to nontoxic hemozoin, which is sequestered in. 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, 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. Chloroquine - FDA prescribing information, side effects and uses. Antimalarial drugs - SlideShare. Chloroquine - FDA prescribing information, side effects.. Chloroquine binds to heme or FP to form the FP-chloroquine complex; this complex is highly toxic to the cell and disrupts membrane function. Action of the toxic FP-chloroquine and FP results in cell lysis and ultimately parasite cell autodigestion. In essence, the parasite cell drowns in its own metabolic products. Hydroxychloroquine HCQ, sold under the brand name Plaquenil among others, is a medication used for the prevention and treatment of certain types of malaria. Specifically it is used for chloroquine-sensitive malaria. Other uses include treatment of rheumatoid arthritis, lupus, and porphyria cutanea tarda. It is taken by mouth. It is also being used as an experimental treatment for SARS-CoV-2. Aminoquinoline, excellent schizonticide, Antimalarial, amebicide, anti inflammatory and local irritant. Mechanism of Action of Chloroquine Malarial parasites digest their own haemoglobin and release highly toxic heme. This heme is used up by parasitic polymerase enzyme and converted to non toxic haemozoin. Since Chloroquine is.
