Efficacy of a topically administered combination of emodepside and praziquantel against mature and immature Ancylostoma tubaeforme in domestic cats.
This paper reports the efficacy of emodepside/praziquantel spot-on (Profender), Bayer AG, Leverkusen, Germany), a novel broad-spectrum anthelmintic for dermal application, against L4 larvae and immature adult and adult stages of Ancylostoma tubaeforme in cats. The formulation contains 2.14% (w/w) emodepside and 8.58% (w/v) praziquantel, with emodepside being active against gastrointestinal nematodes and praziquantel against cestodes. Five randomized, blinded and controlled laboratory studies demonstrated 100% efficacy of emodepside/praziquantel spot-on against mature A. tubaeforme and an efficacy of >95% and >97%, respectively, against L4 larvae and immature adults (based on worm counts after necropsy) at approximately the minimum proposed dose rate in cats of 3.0 mg emodepside and 12.0 mg praziquantel/kg body weight. No adverse reactions to the treatment were observed. It is concluded that emodepside/praziquantel spot-on is an effective and safe treatment against infections with mature and immature A. tubaeforme. Emodepside/praziquantel spot-on will considerably facilitate the treatment of cats against nematodes and cestodes compared with orally administered preparations.
