Title :

Measurement of halofantrine and its major metabolite desbutylhalofantrine in plasma and blood by high-performance liquid chromatography: a new methodology

Abstract :

A new high-performance liquid chromatographic assay for the measurement of halofantrine and desbutylhalofantrine in plasma and whole blood is described. The method involves a smaller sample volume, simplified sample pre-treatment and a shorter run-time, and is adaptable to the measurement of samples dried onto filter paper strips. Using this method, which is both selective and sensitive, plasma concentration versus time profiles for both substances have been investigated following a single oral dose (500 mg) of halofantrine hydrochloride to a healthy adult volunteer. In addition, a clinical study designed to evaluate the disposition and elimination of the two compounds in children with non-severe falciparum malaria is in progress.
