Chloroquine is part of a class of drugs called Anti-malarial, and it was approved in the most recent update to the US Centres for Disease Control guidelines on travel recommendations for the prevention and treatment of Malaria. Chloroquine is also effective at treating infections caused by a different kind of parasite known as amoebae.
