    Chloroquine in vitro concentrations

    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.

Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. Oct 01, 2018 Chloroquine is not active against the gametocytes and the exoerythrocytic forms including the hypnozoite stage P. vivax and P. ovale of the Plasmodium parasites. In vitro studies with Chloroquine demonstrated that it is active against the trophozoites of Entamoeba histolytica.

    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.

  4. When chloroquine was added after the initiation of infection, there was a dramatic dose-dependant decrease in the number of virus antigen-positive cells Fig. 2A. As little as 0.1–1 μM chloroquine reduced the infection by 50% and up to 90–94% inhibition was observed with 33–100 μM concentrations Fig. 2B.

    Previously, chloroquine had been used to study influenza virus replication in vitro. However, the 0.1 mM concentration used was too high to indicate its therapeutic usefulness 9. We thus carried out an in vitro antiviral assay to determine the 50% and 90% inhibitory concentration IC50 and IC90, respectively of chloroquine against influenza A virus subtypes H1N1 and H3N2. The IC 50 of chloroquine for inhibition of SARS-CoV in vitro approximates the plasma concentrations of chloroquine reached during treatment of acute malaria. Addition of chloroquine to infected cultures could be delayed for up to 5 h postinfection, without an important drop in antiviral activity. Chloroquine, an old antimalarial drug, may be.

    Hydroxychloroquine - Hydroxychloroquine A 4-aminoquinoline with antimalarial and immunosuppressive properties. 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.

    The Risk of Retinal Toxicity with Plaquenil - Sjogren's In Sjögren’s, Plaquenil is used to treat many symptoms of Sjögren’s including fatigue, joint symptoms of arthritis and arthralgias joint pain, dry mouth and dry eyes. Similar to its use in systemic lupus erythematosus, many clinicians feel that it is useful in reducing general Sjögren’s “disease activity.”
