Thai soldiers who became slide-positive for malaria while receiving mefloquine chemoprophylaxis were treated with halofantrine to study its efficacy against mefloquine-resistant falciparum malaria. Thirty-two patients received three doses of 500 mg (1,500 mg total) of halofantrine at six-hr intervals, and were then observed for four weeks. Parasite recrudescence following treatment (median 21 days) occurred in seven of 23 patients (30%) who had mefloquine serum concentrations indicative of regular prophylaxis (greater than 500 ng/ml). Serum concentrations of mefloquine in all 32 patients averaged 950 ng/ml (range 26-2,515) prior to halofantrine treatment. The halofantrine serum concentrations were higher in patients cured by halofantrine than in patients with drug failure, but this was not statistically significant. Patients who were cured by halofantrine had parasites that were more sensitive in in vitro testing to mefloquine (mean [inhibitory concentration] IC50 = 12.5 ng/ml) than in patients whose parasitemias recrudesced (mean IC50 = 23.8 ng/ml) (P less than 0.01, by Wilcoxon rank sum test). These observations suggest that the current formulation and regimen of halofantrine are not optimal for the treatment of multiple drug-resistant falciparum malaria from Thailand.
