Abstract The plasma concentrations of the enantiomers of halofantrine and its N-desbutyl metabolite in six patients with malaria were measured after oral administration of 3×750 mg doses of micronised, racemic halofantrine hydrochloride given at 6-hour intervals. Significant differences were observed between the plasma concentrations of the enantiomers both of halofantrine and its N-monodesbutyl metabolite. AUC084h values were higher for (+)halofantrine (9917 μg·ml−1·h) than for (-)-halofantrine (6127 μg·ml−1·h). The clinical significance of these observations is not known. The isomers have equipotent activity in vitro but their relative toxicity has not yet been assessed.
