Many current theories center around how a related medicine, chloroquine, works Chloroquine has been sporadically used in treating SARS-CoV-2 infection. Comment: Review paper summarizing studies related to the pharmacokinetics of chloroquine (published prior to 1989), dosing and mechanism of action in the treatment of malaria and rheumatoid arthritis. malariae, P. Since then, the beneficial effects of quinine and its more advanced synthetic forms, chloroquine and hydroxychloroquine, have been increasingly recognized in a myriad of other diseases in addition to malaria.
