PEREZ, Manuel Alberto et al. Efficacy of the amodiaquine+sulfadoxine-pyrimethamine combination and of chloroquine for the treatment of malaria in Córdoba, Colombia, 2006. Biomédica [online]. 2008, vol.28, n.1, pp.148-159. ISSN 0120-4157.

Introduction. The decrease in the efficacy of antimalarial drugs in the world and in Colombia hampers its control. Objective. The in vivo therapeutic efficacy of the amodiaquine+sulfadoxine-pyrimethamine combination was evaluated in the treatment of uncomplicated Plasmodium falciparum malaria and of chloroquine for P. vivax malaria.    Materials and methods. From May to November < ProductID="2006, in" w:st="on">2006, in vivo efficacy studies of malaria treatments were undertaken in Tierralta, Córdoba, northeastern Colombia. Standard protocols were followed as recommended by the World Health Organization/Panamerican Health Organization, with some modifications. Patients older than two years with single P. falciparum or P. vivax infection, with asexual parasitemia between 500 and 50,000 parasites/µl, were selected according to established inclusion and exclusion criteria. Supervised treatment was administered, and clinical and parasitological follow-up was carried out on days 0 (inclusion), 1, 2, 3, 7, 14, 21 and 28. The outcome was defined as adequate clinical and parasitological response, early therapeutic failure, or late therapeutic failure. Results. Of 53 subjects selected,  50 (94.3%; CI 70%-100%) presented adequate clinical and parasitological response to the amodiaquine+sulfadoxine-pyrimethamine treatment for uncomplicated falciparum malaria.  One patient presented early therapeutic failure, and two  developed late therapeutic fail, the amodiaquine+sulfadoxine-pyrimethamine combination and chloroquine show a high efficacy for the treatment of uncomplicated falciparum and vivax malaria, respectively.
