Inhibition of protein synthesis is also observed, evidently as a secondary effect. Inhibition of DNA replication is proposed as a general mechanism of the antimicrobial action of chloroquine. Plaquenil icd 10 code Hydroxychloroquine generic price Mechanism of Action. Chloroquine is an antimalarial agent. While the drug can inhibit certain enzymes, its effect is believed to result, at least in part, from its interaction with DNA. However, the mechanism of plasmodicidal action of chloroquine is not completely certain. Activity in vitro and in vivo Chloroquine is a 9-aminoquinoline known since 1934. Apart from its well-known antimalarial effects, the drug has interesting biochemical properties that might be applied against some viral infections. Chloroquine exerts direct antiviral effects, inhibiting pH-dependent steps of the replication of several viruses including members of the flaviviruses, retroviruses, and coronaviruses. Its best. Chloroquine is used to prevent or treat malaria caused by mosquito bites in countries where malaria is common. Malaria parasites can enter the body through these mosquito bites, and then live in.

It was the drug of choice to treat malaria until the development of newer antimalarials such as pyrimethamine, artemisinin, and mefloquine. Chloroquine - DrugBank. Chloroquine Oral Uses, Side Effects, Interactions.. Mechanisms of action of hydroxychloroquine and chloroquine.. Chloroquine was known to exert its activity by accumulating in parasite DV and so compromising hemoglobin digestion by the parasite leading to the accumulation. The major action of chloroquine is to inhibit the formation of hemozoin Hz from the heme released by the digestion of hemoglobin. Chloroquine binds to heme or FP to form what is known as 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.
