Malaria Home > Mode of Action of Chloroquine

Most people get malaria from the bite of an infected female Anopheles mosquito. Through the bite, a microscopic parasite called Plasmodium enters the body and causes infection, with malaria symptoms typically appearing 10 to 30 days after a person becomes infected.
 
Chloroquine phosphate (Aralen®) works by killing the Plasmodium parasites that cause the infection. How does it kill the parasites? Chloroquine's mode of action is not entirely clear -- however, it is possible that the drug stops the parasites from reproducing by interfering with their DNA.
