Generic Aralen is a medication that is recommended for the treatment and prevention of malaria. It is also advised for the treatment of liver infection caused by a parasite ameba, the condition called extraintestinal amebiasis. The active drug composition of Generic Aralen is chloroquine, which belongs to a class of drugs called antimalarials and amebicidals. The U.S. Food and Drug Administration (FDA) approved chloroquine for malarial prevention and treatment in 1949. It is quite similar to the antimalarial drug called hydroxychloroquine, which is sold under the brand name Plaquenil. Generic Aralen is a prescription drug so it should be used under the supervision of a medical professional.


Chloroquine is a 4-aminoquinoline compound, which is a white, odorless, bitter-tasting, crystalline substance. The drug is freely soluble in water. It is an antimalarial and amebicidal drug, but it is not clear how it exactly works at treating and preventing malaria and extraintestinal amebiasis, respectively. However, it is presumed that chloroquine acts by preventing the malarial parasite from targeting and entering the human red blood cells (RBCs). By doing so, it does not allow the pathogen to invade the cells, preventing the infection. Please note that Generic Aralen is not advised to treat complicated or advanced cases of malaria. And it works only for certain strains of malarial parasites.
