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 Both chloroquine and hydroxychloroquine are "lysosomotropic" agents that are weak bases - at clinical doses, they accumulate in lysosomes or endosomes, sopping up a proton and thereby alkalinizing them. Mechanism of action: In a study by Aartjan et al, zinc ions (Zn2+) in high intracellular concentrations have been shown to inhibit viral RNA polymerase Mechanism of Action: Description: Hydroxychloroquine is a 4-aminoquinoline derivative.

These drugs interfere with lysosomal activity and autophagy, interact with membrane stability and alter signalling pathways and transcriptional activity, which can result in inhibition of cytokine production and modulation of certain co-stimulatory molecules. 5 uM, respectively). Their mechanism of action is not entirely understood. The Nine Lives of Hydroxychloroquine Most of the science regarding HCQ’s mechanism of action falls in the realm of speculation. It interferes w/ parasite digestive vacuoles by increasing pH and interfering w/ parasite’s ability to metabolise and utilise erythrocyte Hb. Colchicine has multiple effects including disruption of the innate immunity by suppressing the NALP3 inflammasome-driven caspase-1 activation of interleukin 1ß processing and release, and L-selectin expression on neutrophils 5 .. Mechanism of action: In a study by Aartjan et al, zinc ions (Zn2+) in high intracellular concentrations have been shown to inhibit viral RNA polymerase Hydroxychloroquine (HCQ) is recommended for thromboprophylaxis in patients with systemic lupus erythematosus and aPL. Limited data suggest that chloroquine may inhibit the exacerbation of pneumonia, improve lung imaging findings, promote virus-negative conversion, and shorten the disease course.[65119] [65121] [65123] [65124] [65125] [65147] [65148]. Both are used as antimalarial blood schizonticides, and hydroxychloroquine is also frequently used as an antirheumatic. A more sensible but still speculative explanation for the efficacy of the drug in limited studies is:.
