Two controlled, blinded and randomized multi–site clinical field studies evaluated the efficacy and safety of emodepside/praziquantel spot–on in the treatment of gastrointestinal nematode and cestode infections in cats. In a study conducted in Europe, faecal egg count reductions of >98% for all nematode eggs and eggs of Toxocara cati, respectively, were observed in cats treated with emodepside/praziquantel spot–on (Profender®, Bayer AG, Leverkusen, Germany). For a positivecontrol product containing selamectin (Stronghold) reductions of >95% were observed. A 100% reduction of faecal eggs and proglottids was observed in cats treated with emodepside/praziquantel spot–on that were infected with cestodes. In a study conducted in North America, cats were treated with either emodepside/praziquantel spot–on plus a placebo tablet or a combination of two control products containing, respectively, selamectin (Revolution) and epsiprantel (Cestex). Faecal egg count reduction for eggs of T. cati was >99% for both treatments. For faecal eggs and proglottids of Dipylidium caninum reductions of >99 and >97% were recorded for cats treated with emodepside/praziquantel spot–on and the control group, respectively. No adverse reactions were observed in the European study, and only mild ones of short duration in a few cats from both treatment groups of the North American study. The two studies demonstrated that emodepside/praziquantel spot–on is highly efficacious and safe under field conditions.
