摘要
The therapeutic efficacy against notoedric mange of a topical combination of esafoxolaner, eprinomectin and praziquantel (Nexgard((R)) Combo, Boehringer Ingelheim) was evaluated in a masked, controlled clinical study including 14 cats with natural or induced Notoedres cati infestation. Cats were allocated randomly to two groups of seven cats each, to be administered either mineral oil (placebo control) or NexGard((R)) Combo. Each treatment was administered once as spot-on at 0.12 mL per kg body weight (representing the minimum label dosage of NexGard((R)) Combo, i.e. 1.44 mg esafoxolaner, 0.48 mg eprinomectin, and 10.0 mg praziquantel per kg body weight). Live mites were counted in skin scrapings collected within seven days prior to and 14, 27/28, 42 and 56 days after treatment to calculate the percentage efficacy of NexGard((R)) Combo based on the comparison of mean live mite counts of the two groups. Concurrently, mange lesions and clinical signs were scored to establish a clinical success valuation. No live mites were recovered from any NexGard((R)) Combo-treated cats post-treatment, indicating 100% therapeutic efficacy following a single spot-on administration of the novel antiparasitic combination. The clinical success valuations in the NexGard((R)) Combo-treated cats were 14.3%, 42.8%, 100% and 100% at 14, 27/28, 42 and 56 days after treatment, respectively. No health problems were observed throughout the study. L'efficacite therapeutique contre la gale notoedrique d'une association topique d'esafoxolaner, d'eprinomectine et de praziquantel (Nexgard((R)) Combo, Boehringer Ingelheim) a ete evaluee dans une etude clinique controlee et masquee portant sur 14 chats atteints d'une infestation naturelle ou induite par Notoedres cati. Les chats ont ete repartis au hasard en deux groupes de sept chats chacun, traites soit avec de l'huile minerale (controle placebo), soit avec NexGard((R)) Combo. Chaque traitement a ete administre en une seule fois a raison de 0,12 mL par kg de poids corporel (representant la posologie minimale indiquee sur l'etiquette de NexGard((R)) Combo, c'est-a-dire 1,44 mg d'esafoxolaner plus 0,48 mg d'eprinomectine plus 10,0 mg de praziquantel par kg de poids corporel). Les acariens vivants ont ete comptes par grattage de peau et recueillis dans les sept jours precedant le traitement et 14, 27/28, 42 et 56 jours apres le traitement pour calculer le pourcentage d'efficacite de NexGard((R)) Combo base sur la comparaison du nombre moyen d'acariens vivants des deux groupes. Parallelement, les lesions de la gale et les signes cliniques ont ete mesures pour etablir une evaluation du succes clinique. Aucun acarien vivant n'a ete retrouve chez les chats traites par NexGard((R)) Combo apres le traitement, ce qui indique une efficacite therapeutique de 100% apres une administration ponctuelle unique de la nouvelle association antiparasitaire. L'evaluation du succes clinique chez les chats traites par NexGard((R)) Combo etait de 14,3 %, 42,8 %, 100 % et 100 %, respectivement 14, 27/28, 42 et 56 jours apres le traitement. Aucun probleme de sante n'a ete observe tout au long de l'etude.
