The effect of food on the pharmacokinetics of oral fluralaner in dogs. AAPS J. Another factor influencing the pharmacokinetics of fluralaner might be the prandial state of the dog at the time of drug application, as it is well known that feeding affects gastrointestinal physiology and thereby may affect drug absorption and bioavailability [26, 27]. Nevertheless, the CVMP still considers the use of Bravecto® chewable tablets to be acceptably safe [9]. Particularly, fluralaner should be used with caution in dogs with pre-existing epilepsy.

DG, CR, MS, MH, and JG discussed the case and drafted the manuscript. As Bravecto® treatment was tolerated by the Kooikerhondje dog in a previous treatment, general drug hypersensitivity can be excluded. Based on the supposed mechanism of blocking Cys-loop receptors, GABAA receptor agonists such as benzodiazepine drugs or propofol might be a treatment option [29], but until now there is no clinical experience with that at all. The next morning, the dog showed oral dysphagia in the manner of dropping food from the mouth, but was able to ingest the food after several attempts.

Fluralaner inhibits arthropod glutamate-gated chloride channels (GluCls) and GABA-gated chloride channels (GABACls) [12], which structurally belong to the class of so-called Cys-loop receptors [13, 14]. Adverse side effects are thankfully rare and usually mild; however, there have been implications of seizures following administration of Bravecto so this should be avoided with pets who have a history of neurological disorders.

Effects of food on drug absorption. doi: https://doi.org/10.1042/BST0371404. Based on the molecular pharmacology of fluralaner, it has to be discussed if the neurological dysfunction seen in the Kooikerhondje dog in the present case may result from blocking of one of these receptors, which would explain the occurrence of generalized ataxia, myoclonic jerks, tremor of head and body, muscle twitching and oral dysphagia. Insect gamma-aminobutyric acid receptors and isoxazoline insecticides: toxicological profiles relative to the binding sites of [(3)H]fluralaner, [(3)H]-4′-ethynyl-4-n-propylbicycloorthobenzoate, and [(3)H]avermectin.

Welling PG. The dog receives the recommended amount of pellet food (Platinum©) and was 7 months old on the day of the Bravecto® treatment. In this case, improvement of the dog’s condition and disappearance of neurological dysfunction might simply be explained by drug elimination and decline of the relevant drug concentration in the brain. However, as fluralaner has a generally good safety profile and neurologic adverse events only occur in very rare cases, individual factors increasing the drug concentration in the brain or increasing the susceptibility of CNS Cys-loop receptors may come into account. https://www.ema.europa.eu/en/documents/assessment-report/bravecto-epar-public-assessment-report_en.pdf.
