Double-blind studies with mefloquine alone and in combination with sulfadoxine-pyrimethamine in 120 adults and 120 children with falciparum malaria in Vietnam.
In 120 adult Vietnamese patients with uncomplicated falciparum malaria the efficacy of, and tolerance to, mefloquine (M) vs the combination of mefloquine + sulfadoxine + pyrimethamine (MSP) was studied in a double-blind, randomized comparative trial with chloroquine. Also, a double-blind dose finding study of MSP was performed in 120 Vietnamese children with uncomplicated falciparum malaria. In the adults the mean parasite clearance time with M was 3.8 d and with MSP 3.6 d. Defervescence occurred in 2.9 and 3.0 d respectively for M and MSP. There was a 36.8% resistance rate in 38 patients treated with chloroquine. 96% of the children were sensitive or showed a delayed RI response. The lowest dose of MSP (10 mg/kg M + 20 mg/kg S + 1.0 mg/kg P, 1 tablet Fansimef) was as effective as 1.5-2x this dose in children weighing 23-30 kg. Side effects were mild, except for vomiting which required alternative therapy in 4 patients.
