[Halofantrine: for new rules of prescription].
Halofantrine is an antimalarial drug widely prescribed for chloroquine-resistant strains of Plasmodium falciparum. It has been recognized to cause serious deleterious effects which have dampened early enthusiasm for this compound. Basically, the adverse effects involve lengthening of the QTc interval, torsade de pointes and induction of late ventricular potentials. These side effects are related to the quinidine-like effect of the drug which has a chemical structure similar to quinine and quinidinic drugs. More recently, severe haemolytic accidents have been reported suggesting an autoimmunization mechanism. These side effects imply new rules for prescription and more prudent use of halofantrine, especially for prophylaxic therapy against malarial attacks in travellers.
