Chloroquine has been sporadically used in treating SARS-Co V-2 infection. Hydroxychloroquine shares the same mechanism of action as chloroquine, but its more tolerable safety profile makes it the preferred drug to treat malaria and autoimmune conditions. Plaquenil drug eruption Plaquenil for lyme Hydroxychloroquine is a 4-aminoquinoline with immunosuppressive, antiautophagy, and antimalarial activities. Although the 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. Mechanism of action of hydroxychloroquine as an antirheumatic drug. Fox RI1. 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. Box 1 Main mechanisms of actions by hydroxychloroquine and chloroquine Hydroxychloroquine and chloroquine can inhibit certain cellular functions and molecular pathways involved in immune. Currently, there is no evidence to support the use of hydroxychloroquine in SARS-Co V-2 infection. We propose that the immunomodulatory effect of hydroxychloroquine also may be useful in controlling the cytokine storm that occurs late-phase in critically ill SARS-Co V-2 infected patients.
