PARASITICIDAL COMPOSITION COMPRISING A SALICYLANILIDE ANTI-PARASITIC COMPOUND

摘要

An anti-parasiticidal composition presented as a topical "pour-on" product for treating animals infected by parasites which are known to be susceptible to salicylanilides, especially closantel, alone or together with at least one other anti~ parasitic compound of the avermectin or milbemycin type and offers enhanced bioavailability of the salicylanilide by provision of a delivery system comprising at least 20%(v/v) of one or more alcohols, and optionally including a polymeric moiety selected from the group consisting of polyvinylpyrrolidone (PVP), polyoxypropylene/polyoxyethylene block copolymers (poloxamer), and polyethylene glycols (PEG), thereby improving the bioavailability of e.g. closantel (as assessed with respect to blood plasma levels of closantel).
