    It is also useful in treating systemic lupus erythematosus as well as rheumatoid arthritis and Sjögren's Syndrome (all rheumatic disorders).

    The mechanisms of action of hydroxychloroquine and chloroquine remain under continuous study in modern molecular medicine 17,18 using advanced tools in computational biology 19, synthetic biology. According to Raoult, the effect of both chloroquine and its derivative hydroxychloroquine is probably the same since the mechanism of action of these two closely-related molecules is identical, he. Disease-modifying antirheumatic drugs DMARDs are a group of medications commonly used in people with rheumatoid arthritis. Some of these drugs are also used in treating other conditions such as ankylosing spondylitis, psoriatic arthritis, and systemic lupus erythematosus. They work to decrease pain and inflammation.

    Hydroxychloroquine, by decreasing TLR signaling, reduces the activation of dendritic cells thus mitigating the inflammatory process. Toll-like receptor 9 (TLR 9), which recognizes DNA-containing immune complexes, leads to the production of interferon and causes the dendritic cells to mature and present antigen to T cells.

    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.

Cytochrome P450 enzymes converts hydroxychloroquine into its active metabolite, desethyl hydroxychloroquine.6 The onset of action may take up to 4–6 weeks post-commencement of therapy, and it may take 3–6 months to achieve maximal clinical efficacy. The recommended maintenance dose of hydroxychloroquine is 200–400 mg daily.
