Pharmacokinetics of ponazuril after oral administration to healthy llamas (Lama glama)

Abstract

The rate and extent of absorption following oral administration of a single dose of ponazuril were sufficient to result in potentially effective concentrations, and the drug was tolerated well by llamas. At this dose, ponazuril resulted in serum concentrations that were high enough to be effective against various Apicomplexans on the basis of data for other species. The effective ponazuril concentration that will induce 50% inhibition of parasite growth for Eimeria macusaniensis in camelids is currently unknown.
