Abstract: We compared the safety and efficacy of two treatment regimens using sodium artesunate in 91 randomized patients with uncomplicated falciparum malaria acquired in Thailand. One group of 45 patients received 400 mg of artesunate on the first day of treatment and then 200 mg daily for 4 days for a total of 1200 mg (group I: 5-day treatment). A second group of 46 patients received 400 mg of artesunate on the first day of treatment and then 200 mg daily for 6 days for a total of 1600 mg (group II: 7-day treatment). Both regimens were well tolerated. All patients were followed for a total of 28 days. By the third day of treatment, most patients were blood smear negative for parasites. Eighty-two patients completed the 28-day follow-up period and were used for describing the cure rate. All patients treated with the 5-day regimen were cured. In the 7-day treatment group, 98% (39 of 40) of the patients were cured; one patient developed late recrudescence (RI). There were no significant differences in fever clearance or parasite clearance between the two groups. However, 13 patients (five in group I and eight in group II) developed Plasmodium vivax infection during the follow-up period. We conclude that 5- or 7-day regimens of sodium artesunate with a total dose of 1200-1600 mg are effective and safe in treating falciparum malaria acquired in Thailand.
