    Chloroquine pharmacodynamics

    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.

    ChloroquineChloroquine was the first drug produced on a large scale for treatment and prevention of malaria infection. Chloroquine has activity against the blood stages of P. ovale, P. malariae, and susceptible strains of P. vivax and P. falciparum. Eight healthy volunteers who had not taken chloroquine 2 to 12 months previously participated in a single dose study designed to evaluate the pharmacokinetics of chloroquine and some of its metabolites. Each subject received two tablets of chloroquine sulfate 300 mg base only. Hydroxychloroquine HCQ and chloroquine CQ are well absorbed 0.7-0.8 bioavailability when given orally. Severe malnutrition such as kwashiorkor effects absorption but diahrrea does not. Both HCQ and CQ have prolonged half-lives, between 40 and 50 days, and low blood clearance e.g. hydroxychloroquine's blood clearance is 96 ml/min.

    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.

  3. 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.

    Pharmacokinetics, Pharmacodynamics, and Allometric Scaling of Chloroquine in a Murine Malaria Model Article PDF Available in Antimicrobial Agents and Chemotherapy 5583899-907 June 2011. Sep 23, 2019 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. Chloroquine enters the red blood cell, inhibiting the parasite cell and digestive vacuole by simple diffusion. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion.
