    Hydroxychloroquine sulfate mechanism of action


    Chloroquine has been sporadically used in treating SARS-Co V-2 infection. Hydroxychloroquine shares the same mechanism of action as chloroquine, but its more tolerable safety profile makes it the preferred drug to treat malaria and autoimmune conditions.

    Antimalarial action Hydroxychloroquine binds to DNA, interfering with protein synthesis. It also inhibits DNA and RNA polymerases. It’s active against asexual erythrocytic forms of Plasmodium malariae, P. ovale, P. vivax, and many strains of P. falciparum. Hydroxychloroquine is a 4-aminoquinoline with immunosuppressive, antiautophagy, and antimalarial activities. Although the precise mechanism of action is unknown, hydroxychloroquine may suppress immune function by interfering with the processing and presentation of antigens and the production of cytokines. Although its precise mechanism of action is unknown, hydroxychloroquine may suppress immune function by interfering with the processing and presentation of antigens and the production of cytokines. This agent is highly active against the erythrocytic forms of P. vivax and malariae and most strains of P. falciparum but not the gametocytes of P. falciparum.

    Currently, there is no evidence to support the use of hydroxychloroquine in SARS-Co V-2 infection. We propose that the immunomodulatory effect of hydroxychloroquine also may be useful in controlling the cytokine storm that occurs late-phase in critically ill SARS-Co V-2 infected patients.

  6. Hydroxychloroquine affects the function of lysozomes in humans as well as plasmodia. 4 Altering the pH of the lysozomes reduces low affinity self antigen presentation in autoimmue diseases and interferes with the ability of plasmodia to proteolyse hemoglobin for their energy requirements. 4 Hydroxychloroquine has a long duration of action as it may be taken on a weekly basis for some indications. 8 Hydroxychloroquine may lead to severe hypoglycemia and so diabetic patients are advised to.

    Nov 09, 2018 Hydroxychloroquine is used to treat or prevent malaria, a disease caused by parasites that enter the body through the bite of a mosquito. Malaria is common in areas such as Africa, South America, and Southern Asia. This medicine is not effective against all strains of malaria. Hydroxychloroquine is also used. Mechanism of action The precise mechanism by which hydroxychloroquine exhibits activity against Plasmodium is not known. Hydroxychloroquine, like chloroquine, is a weak base and may exert its effect by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme. Dosage and Administration One tablet of 200 mg of hydroxychloroquine sulfate is equivalent to 155 mg base. Malaria Suppression—In adults, 400 mg =310 mg base on exactly the same day of each week. In infants and children, the weekly suppressive dosage is 5 mg, calculated as base, per kg of body weight.
