Results from a U.S. dog owner survey on the treatment satisfaction and preference for fluralaner against flea and tick infestations

Abstract Background: Fluralaner is a potent acaricide and insecticide effective against flea and tick (F/T) infestations on dogs and cats. Fluralaner for dogs can be administered orally as a flavored chew with up to a 12-week redosing interval, about three-fold less frequently than monthly F/T medications. This study surveyed dog owners who currently administer fluralaner […]

The speed of kill of fluralaner (BRAVECTO™) against Ixodes ricinus ticks on dogs

Abstract Background: Pathogens that are transmitted by ticks to dogs, such as Anaplasma phagocytophilum, Babesia spp., Borrelia burgdorferi sensu latu, and Ehrlichia canis, are an increasing problem in the world. One method to prevent pathogen transmission to dogs is to kill the ticks before transmission occurs. Fluralaner (Bravecto™) is a novel isoxazoline insecticide and acaricide […]

Fluralaner activity against life stages of ticks using Rhipicephalus sanguineus and Ornithodoros moubata IN in vitro contact and feeding assays

Abstract Background: Fluralaner is a novel isoxazoline eliciting both acaricidal and insecticidal activity through potent blockage of GABA- and glutamate-gated chloride channels. The aim of the study was to investigate the susceptibility of juvenile stages of common tick species exposed to fluralaner through either contact (Rhipicephalus sanguineus) or contact and feeding routes (Ornithodoros moubata). Methods: […]

A quantitative evaluation of the extent of fluraner uptake by ticks (Ixodes ricinus, Ixodes scapularis) in fluralaner (BRAVECTO™) treated vs. untreated dogs using the parameters tick weight and coxal index

Abstract Background: Fluralaner is a new antiparasitic drug that was recently introduced as Bravecto™ chewable tablets for the treatment of tick and flea infestations in dogs. Most marketed tick products exert their effect via topical application and contact exposure to the parasite. In contrast, Bravecto™ delivers its acaricidal activity through systemic exposure. Tick exposure to […]

Onset of activity of fluralaner (BRAVECTO™) against Ctencephalides felis on dogs

Abstract Background: Fluralaner (Bravecto™) is a novel systemic insecticide and acaricide that provides long persistent antiparasitic activity following a single administration at the minimum dose of 25 mg/kg body weight. Methods: Three negative controlled, randomized studies were conducted in dogs to evaluate the start to kill (1 study) and the speed of flea kill (2 […]

Fluralaner, a novel isooxazoline, prevents flea (Ctenocephalides felis) reproduction in vitro and in a simulated home environment

Abstract Background: Fluralaner, a novel isoxazoline, has both acaricidal and insecticidal activity through potent blockage of GABA- and L-glutamate-gated chloride channels. This study investigated the in vitro and in vivo effects of fluralaner exposure on flea (Ctenocephalides felis) reproduction. Methods: Blood spiked with sub-insecticidal fluralaner concentrations (between 0.09 and 50.0 ng/mL) was fed to fleas […]

A randomized, blinded, controlled USA field study to assess the use of fluralaner tablets in controlling canine flea infestations

Abstract Background: The novel isoxazoline molecule fluralaner provides 12 weeks activity against fleas and 8 to 12 weeks against tick infestations according to label claims. Methods: This blinded, multi-center study in client-owned dogs evaluated the flea control provided by a single oral fluralaner treatment (25–56 mg/kg; Bravecto™, Merck Animal Health) compared to a control group […]

The effect of food on the pharmacokinetics on oral fluralaner in dogs

Abstract Background: Fluralaner is a novel systemic ectoparasiticide for dogs providing long-acting flea- and tick-control after a single oral dose. The pharmacokinetics of orally administered drugs may be influenced by feeding. This study investigated the influence of concurrent feeding on fluralaner pharmacokinetics. Methods: Twelve fasted or fed beagles received a single oral administration of 25 […]

Pharmacokinetics of fluralaner in dogs following a single oral or intravenous administration

Abstract Background: Fluralaner is a novel systemic insecticide and acaricide. The purpose of these studies was to investigate the pharmacokinetic properties of fluralaner in Beagle dogs following single oral or intravenous (i.v.) administration. Methods: Following the oral administration of 12.5, 25 or 50 mg fluralaner/kg body weight (BW), formulated as chewable tablets or i.v. administration […]

Plasma pharmacokinetic profile of fluralaner (BRAVECTO™) and ivermectin following concurrent administration to dogs

Abstract Background: Fluralaner is a novel systemic ectoparasiticide for dogs providing immediate and persistent flea, tick and mite control after a single oral dose. Ivermectin has been used in dogs for heartworm prevention and at off label doses for mite and worm infestations. Ivermectin pharmacokinetics can be influenced by substances affecting the p-glycoprotein transporter, potentially […]
