Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it. Chloroquine resistant plasmodium falciparum Chloroquin vs quinine Can hydroxychloroquine stop bone graft osseointegration Chloroquine is only found in individuals that have used or taken this drug. It is a prototypical antimalarial agent with a mechanism that is not well understood. It has also been used to treat rheumatoid arthritis, systemic lupus erythematosus, and in the systemic therapy of amebic liver abscesses. 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. MECHANISM OF ACTION. Plaquenil increases the pH of lysosomes and impairs complement-dependent antigen-antibody reactions. It also inhibits the chemotaxis of eosinophils and locomotion of neutrophils. SUMMARY OF EVIDENCE in development Ponticelli C et al. 2017 “Hydroxychloroquine in systemic lupus erythematosus SLE” Expert Opin Drug Saf. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

Mechanism Chloroquine phosphate is a 4-aminoquinoline compound for oral administration. Chloroquine is an antimalarial and amoebicidal drug. The drug possesses antimalarial actions and exerts a beneficial effect in lupus erythematosus chronic discoid or systemic and acute or chronic rheumatoid arthritis. Hydroxychloroquine is classified as an anti-malarial drug. It is similar to chloroquine and is useful in treating several forms of malaria as well as lupus erythematosus and rheumatoid arthritis. Its mechanism of action is unknown. Malarial parasites invade human red blood cells.
