    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.

    Mechanism of action of chloroquine. Entry into the parasitized RBCs; 1. Accumulation in food vacuole of the parasite- role of pH gradient chloroquine trapping Affects asexual cycle of plasmodium specie. Once administered, it has to enter site of action. It rapidly enters and gets concentrated in food vacuole, present within erythrocytes. Chloroquine is commonly used to study the role of endosomal acidification in cellular processes 2, 3, such as the signaling of intracellular TLRs. Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation 4. References. 1. Chloroquine is the drug of choice in the few malaria-endemic areas free of CRPf. Combining chloroquine and proguanil is an option for CRPf when other first-line antimalarials are contraindicated. Dosage should be calculated in terms of the base. The adult chloroquine dose is 300 mg base weekly or in some countries 100 mg base daily.

  7. 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 may also interfere with the biosynthesis of nucleic acids.

    Resistance to chloroquine of malaria strains is known to be associated with a parasite protein named PfCRT, the mutated form of which is able to reduce chloroquine accumulation in the digestive vacuole of the pathogen. 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 mechanism of drug action and resistance in Plasmodium falciparum.

Quinoline-containing drugs such as chloroquine and quinine have had a long and successful history in antimalarial chemotherapy.

    In every pregnancy, a woman starts out with a 3-5% chance of having a baby with a birth defect. This sheet talks about whether exposure to hydroxychloroquine may increase the risk for birth defects over that background risk. Hydroxychloroquine for the prevention of fetal growth.

    Immune & Autoimmune - Lupus Plaquenil - Can It Work Quickly? Hi - I just started Plaquenil 400 mg a day two week ago and I started feeling less achy and tired a few days ago. Is it possible for it to work quicker in some people? I've heard it can take months, but I must say that I haven't felt like this since I was a kid - not achy or stiff. Has anyone had a similar

    Drug Safety in Pregnant & Nursing Women. Anti-malarial drugs hydroxychloroquine, chloroquine are considered pregnancy category C drugs. While there is evidence of risk for damage to the eye and ear, if the benefits of these drugs in controlling RA symptoms are judged to outweigh the risks, they may continue to be used during pregnancy. 1,2
