    Mechanism of chloroquine resistance


    Resistance to currently available antimalarial drugs has been confirmed in only two of the four human malaria parasite species, first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted.

Chloroquine is a 9-aminoquinoline known since 1934. Apart from its well-known antimalarial effects, the drug has interesting biochemical properties that might be applied against some viral infections. Chloroquine exerts direct antiviral effects, inhibiting pH-dependent steps of the replication of several viruses including members of the flaviviruses, retroviruses, and coronaviruses. Its best. ChloroquineResistance In Plasmodium Falciparum. With cholorquine there is emergence of resistance, which has limited its use. Primarily highly effective against febrile illness, relief is quickly achieved within 24 hours.
