Extra-label use of ivermectin in some minor ruminant species: pharmacokinetic aspects.

The characterisation of ivermectin pharmacokinetics can be used to predict and to ensure an optimal activity in the target species and for designing programmes aimed for parasite control. Ivermectin pharmacokinetic studies performed in several minor ruminant species are reviewed in this paper with the aim of facilitating the adoption of rational basis for the establishment of appropriate dosage schedules.
