    Based on PBPK models results, a loading dose of 400 mg twice daily of hydroxychloroquine sulfate given orally, followed by a maintenance dose of 200 mg given twice daily for 4 days is recommended for SARS-Co V-2 infection, as it reached three times the potency of chloroquine phosphate when given 500 mg twice daily 5 days in advance. It's important to note that the study was examining use of chloroquine and hydroxychloroquine for treatment and prophylaxis of Covid19 infection (anti-viral activity) as well as postulating immuno-modulatory benefits against the 'cytokine storm' which precipitates later ARDS-type respiratory failure.

    In Vitro Antiviral Activity and Projection of Optimized Dosing Design of Hydroxychloroquine for the Treatment of Severe Acute Respiratory Syndrome Coronavirus 2 SARS-CoV-2 – a publication from March 2020 indicating that Hydroxychloroquine was more potent than Chloroquine. The publication further proposes the following treatment schedule. Plaquenil is the brand name for the prescription drug hydroxychloroquine. It's used to treat and prevent malaria infection, and to reduce symptoms and progression of autoimmune diseases such as lupus, rheumatoid arthritis, and others. That hydroxychloroquine has some antiviral activity in vivo has been reported by two phase II clinical trials.34, 35 The first trial was a small randomised, doubleblind, placebo

    As a doc with RA, I know that when my hydroxychlorquine dose is upped, I have to take the long view of 3 months when considering if it has helped with inflammation.

    Chloroquine and the 4-aminoquinoline drug hydroxychloroquine belong to the same molecular family. Hydroxychloroquine differs from chloroquine by the presence of a hydroxyl group at the end of the side chain the N-ethyl substituent is β-hydroxylated. This molecule is available for oral administration in the form of hydroxychloroquine sulfate. Hydroxychloroquine, hydroxyurea and didanosine as initial therapy for HIV-infected patients with low viral load safety, efficacy and resistance profile after 144 weeks. Depending on the viral challenging doses and the methods adopted to detect the antiviral effects, the inhibitory concentrations fell within the 05–10 μmol/L range—ie, clinically achievable in plasma during malaria treatment LDT, AS, ID, RC, and AC, unpublished data.

    Lupus is an auto-immune disease in which the immune system cannot distinguish between threats (like viruses and bacteria), and healthy cells and tissue.
