PubChemThe mechanism of plasmodicidal action of chloroquine is not completely certain. Chloroquine binds to heme or FP to form the FP-chloroquine complex; this complex is highly toxic to the cell and disrupts membrane function. Action of the toxic FP-chloroquine and FP results in cell lysis and ultimately parasite cell autodigestion. In essence, the parasite cell drowns in its own metabolic products. The antimalarial agents chloroquine and hydroxychloroquine have been used widely for the treatment of rheumatoid arthritis and systemic lupus erythematosus. These compounds lead to improvement of clinical and laboratory parameters, but their slow onset of action distinguishes them from glucocorticoids and nonsteroidal antiinflammatory agents.

Blood levels of racemic chloroquine and its main metabolites desethylchloroquine and bisdesethylchloroquine were measured in 29 patients treated chronically for rheumatoid arthritis. In six patients, the concentrations were followed during a one day dosage interval. There was considerable intersubject variability in the steady state blood concentrations of chloroquine range 36.6 to 3895 ng.
