I would appreciate feedback on the reasoning outlined below. I have convinced myself that it makes sense, but am looking for independent feedback and have been struggling to get it. Chloroquine transfection calcium phosphate Lupus like illness normal blood work plaquenil effective Is there an ed treatment when taking plaquenil A study of about 200 patients with a history of hydroxychloroquine retinopathy, including 36 Asian patients, found that the pericentral pattern occurred in half the Asian patients but only 2% of the white patients. 31 The mechanism for this finding is unclear, but because pericentral retinopathy spares the macula, it can be missed using standard screening methods. Hydroxychloroquine HCQ is nearly identical in structure to CQ and has a similar mechanism of action and therapeutic efficacy in rheumatological and infectious diseases. Like CQ, it also has a long half-life, and a very high volume of distribution. The major proposed mechanisms of action of antimalarials on the immune system include 1 interference with lysosomal acidification and inhibition of proteolysis, chemotaxis, phagocytosis, and antigen presentation 9, 10; 2 decreasing macrophage-mediated cytokine production, especially interleukin IL-1 and IL-6 ; 3 inhibition of phospholipase A2 and thereby antagonizing the effects of prostaglandins 12, 13; 4 absorption and blocking of UV light cutaneous reactions ; 5 binding. , etc.), or provide argument why this is a dumb idea. I would greatly appreciate it if someone could knit-pick this with a fine tooth comb and try and find some mistake I've made (off by a order of magnitude? Mechanism of action hydroxychloroquine New use for an old treatment Hydroxychloroquine as a., COVID-19 Prophylaxis in Healthcare workers. - Health 2019 Is plaquenil processed through the liver Chloroquine and hydroxychloroquine are drugs derived from the quinoline molecule. Both are used as antimalarial blood schizonticides, and hydroxychloroquine is also frequently used as an antirheumatic. Their mechanism of action is not entirely understood. However, despite their varying therapeutic dosage and toxicity. Chloroquine and hydroxychloroquine – Knowledge for medical.. Hydroxychloroquine From Malaria to Autoimmunity SpringerLink.

Author information 1Department of Rheumatology, Scripps Clinic and Research Foundation, La Jolla, CA 92037. The antimalarial agents chloroquine and hydroxychloroquine have been used widely for the treatment of rheumatoid arthritis and systemic lupus erythematosus. Mechanism of action. Hydroxychloroquine increases lysosomal pH in antigen-presenting cells. In inflammatory conditions, it blocks toll-like receptors on plasmacytoid dendritic cells PDCs. citation needed Hydroxychloroquine, by decreasing TLR signaling, reduces the activation of dendritic cells and the inflammatory process.
