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. Chloroquine is a tertiary amine that freely diffuses across the membrane of the parasites food vacuole Hydroxychloroquine (HCQ), sold under the brand name Plaquenil among others, is a medication used to prevent and treat malaria in areas where malaria remains sensitive to chloroquine. malariae and P. It passively diffuses through cell membranes and into lysosomes, where it becomes protonated and cannot leave. Chloroquine is the prototype anti malarial drug, most widely used to treat all types of malarial infections. Chloroquine acts exclusively in the erythrocyte stage of malaria parasites. Hemozoin collects in the digestive vacuole as insoluble crystals. Let’s take a few minutes to learn how precisely quinine is thought to act. malariae, P. Resistance to chloroquine of malaria strains is known to be associated with a parasite protein named PfCRT, the mutated form of which is able to reduce chloroquine accumulation in the digestive vacuole of the pathogen The clinical usefulness of chloroquine, and in some recent cases of quinine as well, has been much reduced by the evolution and spread of chloroquine resistant malaria parasites.
