The choice of appropriate artemisin-based combination therapy depends on several factors (cost, efficacy, safety, reinfection rate, and simplicity of administration). In this study, we tested the hypothesis that artesunate-mefloquine (ArtequinTM) is as efficacious as artemether-lumefantrine (Coartem®) in treatment of uncomplicated Plasmodium falciparum malaria. The study was carried out from August 2004 through February 2005 in Kambila, Mali. Subjects with weights
10 kg and uncomplicated malaria were enrolled. Artesunate-mefloquine was given once a day for three days and artemether/lumefantrine twice a day for three days. A total of 470 (235 in each arm) patients were enrolled. The unadjusted 28-day cure rate was higher in artesunate-mefloquine arm than in the artemether-lumefantrine arm (79.7% versus 67.8%; P < 0.004). After correction for reinfection, the 28-day cure rates were similar in the two groups (96.04% versus 96.93%). Artesunate-mefloquine is well-tolerated and is as effective as artemether-lumefantrine for the treatment of P. falciparum malaria. Artesunate-mefloquine also prevented more new infections.
