Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Study Drugs were dihydroartemisinin-piperaquine (DP), artesunate-mefloquine (ASMQ) and Chloroquine (CQ). One group was treated with DP daily over 3 days, and another group was treated with ASMQ daily over 3 days for uncomplicated Plasmodium falciparum malaria. In a separate group of patients with P. vivax malaria, CQ alone was used for treatment.

DP (oral tablet) with a dose of 4mg/kg for D and 20mg/kg for P daily for 3 days based on the weight group

ASMQ (oral tablet) with AS at a dose of 11-14 mg/kg and with MQ at a dose of 22-28 mg/kg daily based on the weight group

CQ (oral tablet) at 10mg/kg on Day1, 10mg/kg on Day2 and 5 mg/kg on Day3 based on the weight group
Intervention code [1] 284215 0
Treatment: Drugs
Comparator / control treatment
No control and comparator group. This was a single group trial. In falciparum infected patients in Preah Vihear, DP was tested first and when it was finished ASMQ was tested for another group of patients, in Pailin and Rattanakiri only DP was tested. In a separate group of vivax infected patients, CQ was tested in the three sites.
Control group
Uncontrolled
