Treatment of imported cases of falciparum malaria in France with halofantrine.

Halofantrine is a 9-phenanthrenemethanol which is effective against multi-drug resistant strains of Plasmodium falciparum. It has been shown to be highly effective and extremely well tolerated in the treatment of imported cases of falciparum malaria in France. A total of 1,500 mg administered in three 500 mg doses at six-hour intervals results in a 100% cure rate in semi-immune subjects. This dosage should be repeated after 14 days to obtain the same cure rate in non-immune patients. Minor clinical side effects included epigastric pains, nausea and, in one case, a skin rash.
