Halofantrine has been given to 14 children and 15 adults suffering from an acute attack of P. falciparum malaria and living in Dakar (Senegal) to a total dose of 24 mg/kg/body weight for the first group and 1,500 mg for the second in 3 times at 6-hourly intervals. This treatment has allowed the fever to clear in all cases within 36.3 +/- 19.9 hours and headache to disappear at D3 in 93.1% of cases. A reduction by 93.6% of the average parasite density which amounted before treatment to 27,710 trophozoites/mm3 of blood has been recorded from the day following the beginning of treatment and the parasite clearance obtained in all the patients of whom had chloroquine-resistant P. falciparum strains in mean time of 58.0 +/- 14.7 hours. In 3 cases (10.7%) a recrudescence of parasitemia has been noticed in D14. Only 1 of them was treated again with halofantrine which proved efficient from D2. The only adverse reactions have been nausea, vomiting, a slight diarrhoea and dizziness which affected only 13.8% of the patients. No abnormality has been noticed at a biological level. These results confirm the efficacy and good tolerance of halofantrine and allow to list it among the resource drugs used for the treatment of chloroquine-resistant P. falciparum malaria in our area.

The antimalarial efficacy of halofantrine was compared with mefloquine in an open-label, randomized comparative trial in adult male patients with acute uncomplicated falciparum malaria. Twenty-eight patients received halofantrine and 27 received mefloquine. Halofantrine was administered in 3 doses of 500 mg at 6 hour intervals and mefloquine was administered in divided doses of 1,250 mg or 1,500 mg depending on whether the patients weighed less than or more than 60 kg. The patients were followed for 42 days and observed for drug tolerance and evidence of recrudescence. Response to treatment was favorable with both drugs, but three patients (two treated with halofantrine and one with mefloquine) did not completely eliminate malaria parasites from peripheral blood films in seven days. The parasite and fever clearance times were 75.6 and 55.7 hours, and 80.1 and 61.3 hours, respectively for halofantrine and mefloquine. However, 12 patients recrudesced during the 42 day follow-up period. Nine of these had been treated with halofantrine and three with mefloquine. The 42-day cure rate for the two drugs was 56% and 84%, respectively. The side-effects of halofantrine and mefloquine were comparable and transient. These are diarrhea, dizziness, orthostatic hypotension and black out. However, vomiting was found to be more common in mefloquine group (41% vs 22%).

The standard first-line treatment for malaria in adults in Papua New Guinea is chloroquine; for severe and treatment-failure malaria standard therapy is a combination of quinine and Fansidar (sulphadoxine-pyrimethamine). These standard treatments are currently under revision. The present study evaluated the effect of halofantrine in treatment-failure falciparum malaria in adults in Port Moresby compared to standard therapy. In the halofantrine group all parasites were cleared by day 5 after starting therapy, in the quinine-Fansidar group by day 7. There was no evidence of recurrence of parasitaemia during the 21-day follow-up in either group. Nausea was associated with halofantrine use in 68% of patients. In the quinine-Fansidar group 79% had muffled deafness, 32% tinnitus and 26% dizziness; 32% of patients withdrew from treatment on day 2 because of intolerance to quinine. Halofantrine in this study population provided an efficacy against treatment-failure falciparum malaria similar to that of quinine-Fansidar, with a more favourable profile of adverse effects.
