USEFUL HIGH LOAD CONCENTRATE COMPOSITIONS FOR CONTROL OF ECTO-AND ENDO-PARASITES

摘要

High load concentrate compositions comprising metaflumizone, a substantially water-insoluble anti-parasitic macrolide compound,such as moxidectin, an optional bridging agent, a surfactant, and a suitable carrier solvent are prepared. These compositions may be topically administered to animals, and are useful for preventing or treating ectoparasitic infestations in warm-blooded animals for prolonged periods of time. Additionally, they may be further diluted to provide other types of formulations useable for both topical and oral administration.
