    4 aminoquinolines 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.

    The 4-aminoquinoline antimalarials are membrane-soluble weak bases known to accumulate in malaria-infected erythrocytes,11 and it is therefore relevant that the parasite digestive vacuole lysosome, the site of haemoglobin digestion, where the first effects of chloroquine are seen12 and which has been proposed as the main site of drug uptake,13 is enclosed by a lipoprotein membrane, and has an acidic pH around 5.2.14 At this pH, the 4-aminoquinolines will be di-protonated doubly positively. 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. Chloroquine and hydroxychloroquine are 4-aminoquinolines. Quinacrine has a side chain similar to that in chloroquine, but is based on an acridine nucleus

    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. Hydroxychloroquine Plaquenil® is a 4-amino-quinoline antimalarial medication that is widely used to treat systemic lupus erythematosus SLE, rheumatoid arthritis, and related inflammatory and dermatological conditions. It is a hydroxylated version of chloroquine, with a similar mechanism of action.

    In the last ten years, the widespread increase in Plasmodium falciparum resistance to chloroquine has prompted research into antimalarial 4-aminoquinolines, empirically used up to now. The mechanism of action of 4-aminoquinolines is characterized by the concentration of the drug in the digestive vacuole of the intraerythrocytic parasite. Amodiaquine is one of the most potent antimalarial 4-aminoquinolines known and remains effective against chloroquine-resistant parasites, but toxicity issues linked to a quinone-imine metabolite limit its clinical use. Hypersensitivity reaction to chloroquine, hydroxychloroquine or 4-aminoquinolines Contraindication to taking chloroquine as prophylaxis e.g. known epileptic, creatinine clearance 10 ml/min Already taking chloroquine, hydroxychloroquine or 4-aminoquinolines

    Saturday was a week since I stopped taking Plaquenil, aka Hydroxychloroquine, per my doctor’s instructions, and I think I am going through some form of withdrawal. My Take on New Ocular Screening Guidelines for Plaquenil. Plaquenil Oral Uses, Side Effects, Interactions, Pictures. Let me tell you what weaning down from Plaquenil is like.
