Sanofi-Aventis | Aralen (Medication)


Aralen/chloroquine is an antimalarial and amebicidal drug. Aralen does not prevent relapses in patients with vivax or malariae malaria because it is not effective against exoerythrocytic forms of the parasite, nor will it prevent vivax or malaria infection when administered as a prophylactic. It is highly effective as a suppressive agent in patients with vivax or malaria, in terminating acute attacks, and significantly lengthening the interval between treatment and relapse. ...
