Overview
Plain-language summary, compiled from the cited regulatory records
Chloroquine is an antimalarial medication belonging to the aminoquinoline drug class [1]. It is approved for the treatment of uncomplicated malaria caused by susceptible strains of *P. falciparum*, *P. malariae*, *P. ovale*, and *P. vivax* [1]. Chloroquine is also indicated for the prophylaxis (prevention) of malaria in areas where chloroquine resistance is not a concern [1]. Additionally, it is used for the treatment of extraintestinal amebiasis [1]. It is important to note that chloroquine does not prevent relapses in individuals with vivax or ovale malaria because it is not effective against certain forms of the parasite [1].
This medication is available under various brand names [1].
