Key result
Pretreatment with mefloquine potentiated the QTc-prolonging effects of halofantrine by increasing its blood concentrations two to six times compared to halofantrine alone.
Why the study?
Does mefloquine pretreatment potentiate halofantrine-induced QTc prolongation in anaesthetized rabbits?
Does mefloquine pretreatment potentiate halofantrine-induced QTc prolongation in anaesthetized rabbits?
Mefloquine potentiates halofantrine-induced QTc prolongation by increasing circulating concentrations of halofantrine, highlighting a significant pharmacokinetic drug-drug interaction.

Mefloquine-halofantrine QTc interaction merits preclinical vigilance; leaves open human translation and clinical relevance.
Lightbown et al. (2001) studied QTc prolongation. Mefloquine pretreatment followed by halofantrine vs. Halofantrine alone or mefloquine alone was evaluated on QTc interval and blood halofantrine concentrations. Pretreatment with mefloquine potentiated the QTc-prolonging effects of halofantrine by increasing its blood concentrations two to six times compared to halofantrine alone.
