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. Pharmacogenetics. Isoxazolines: a novel Chemotype highly effective on Ectoparasites. One of them is a defect of the multidrug resistance (MDR1) drug efflux carrier at the blood-brain barrier (commonly referred to as MDR1 nt230(del4)), frequently present in Collie, Australian Shepherd, Shetland Sheepdog, Longhaired Whippet, White Swiss Shepherd and some other breeds [18], which leads to increased drug penetration into the brain [19]. Additionally, breed-related differences in body constitution might play a role for the margin of safety of drugs [25]. Kilp S, Ramirez D, Allan MJ, Roepke RK, Nuernberger MC. The FDA is alerting pet owners and veterinarians of the potential for neurologic adverse events in dogs and cats when treated with drugs that are in the isoxazoline class. Weight loss 5.

These products are approved for the treatment and prevention of flea infestations, and the treatment and control of tick infestations. 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. The dog showed intermittent inability to walk and signs of disturbed equilibrium.

During the night, the dog slept in his kennel with shallow breathing and hardly reacted after vocal or tactile stimulation. All symptoms were transient and the dog fully recovered without any treatment after 10 h. This case report may help to better classify adverse drug reactions after application of isoxazoline drugs and documents a good prognosis even after occurrence of severe neurological dysfunction in the present case. The neurological manifestations included tremor, ataxia, peripheral neuropathy, dyskinesia, myoclonic jerks, extrapyramidal hypertony, and altered mental status. A Merck spokesperson sent Strickland an email stating that of the 34 million doses of the medication that have so far been dispensed, the incidence of serious adverse side effects are less than .01%.

Even though the data sheet warns that neurological side effects can occur, it only states in less than 0.1% of cases. Furthermore, a combination of different individual factors might have affected the bioavailability, pharmacokinetics and brain penetration of fluralaner in the Kooikerhondje dog and thus may have provoked the neurological dysfunction. https://www.fda.gov/animal-veterinary/cvm-updates/animal-drug-safety-communication-fda-alerts-pet-owners-and-veterinarians-about-potential-neurologic.

As we have been helping so many severely damaged pets from this drug, some are dying before we could help them. However, most of these cases are documented inadequately and none of them is reported and discussed in the literature. This can provoke neurological toxicity in MDR1 mutant dogs even at standard dosage, as it is well known for drugs like ivermectin [20]. Single experiments on housefly-head and rat-brain membranes as well as on recombinantly expressed individual receptors point to a significantly lower binding affinity of fluralaner to vertebrate receptors compared with arthropod receptors [1, 5, 15].

PubMed  Cite this article. Insect Biochem Mol Biol. 1996;69(3):173–98. However, currently only few factors are known that affect the pharmacokinetic profile and brain penetration of fluralaner. Some of them included severe neurologic adverse events such as tremors, ataxia and seizures [8]. Furthermore, the premedication of the dog with milbemycin oxime plus praziquantel one month prior to Bravecto® treatment may have increased brain penetration of fluralaner, e.g. These could include inter-individual variability in gastrointestinal pH, time of gastric emptying, duration of intestinal transit, plasma protein binding as well as age and sex of the animal [23, 24]. Google Scholar. By . Again, many of these started . However, fluralaner was shown to be safe when administered concurrently with milbemycin oxime + praziquantel [22]. She was still walking badly and had serious vision problems. 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. Blood in stools 5. ... She had him for about a month before she administered Bravecto to … CR and MS clinically examined the dog and described the case.
