Abstract

Background Large amount of data show that chloroquine and
pyrimethamine-sulfadoxine (PS) as standard drugs for falciparum
malaria cause resistance; for that reason new drugs or combina-
tion drugs are urgently needed. Artemether is one of the new
drugs. It has been studied extensively in China and Southeast
Asia during the past 10 years. The effectiveness of this drug in
clearing parasites has been thoroughly documented.
Objective The objective of this study was to investigate the
efficacy of the combination of chloroquine and PS compared to
artemether and PS in the treatment of uncomplicated falciparum
malaria.
Methods We did a single-blind randomized study on 60 children
with uncomplicated falciparum malaria. Thirty children were
treated with chloroquine (10 mg/kg for 2 days, then 5 mg/kg in
the 3 rd day) and PS (pyrimethamine 1-1.5 mg/kg single dose on
the 1 st day) and the other 30 children were treated with artemether
(4 mg/kg/day for 3 days) and PS. All patients were admitted to
hospital for at least 7 days.
Results Fever clearance time was significantly shorter in the group
that received artemether and PS compared to that in the chloro-
quine-and-PS group (42 hours vs. 75 hours 50 minutes, p<0.0001).
Parasite clearance time was significantly different between the
group that received artemether and PS and the chloroquine-and-
PS group (2.5 days vs. 3.1 days, p=0.04). The cure rate in the
chloroquine-and-PS group was 28/30 and that of the artemether-
and-PS group was 30/30. Nausea and vomiting were found in 1
patient treated with chloroquine and PS.
Conclusion The combined treatment of artemether and PS was
well tolerated. No adverse reactions attributable to the treatment
were noted
