Mode of action

Fluralaner inhibits γ-aminobutyric acid (GABA)-gated chloride channels (GABAA receptors) and L-glutamate-gated chloride channels (GluCls).{{cite journal | vauthors = Gassel M, Wolf C, Noack S, Williams H, Ilg T | title = The novel isoxazoline ectoparasiticide fluralaner: selective inhibition of arthropod γ-aminobutyric acid- and L-glutamate-gated chloride channels and insecticidal/acaricidal activity | journal = Insect Biochemistry and Molecular Biology | volume = 45 | pages = 111–124 | date = February 2014 | pmid = 24365472 | doi = 10.1016/j.ibmb.2013.11.009 | doi-access = free | bibcode = 2014IBMB...45..111G }} Potency of fluralaner is comparable to fipronil (a related GABA-antagonist insecticide and acaricide).{{cite journal | vauthors = Asahi M, Kobayashi M, Matsui H, Nakahira K | title = Differential mechanisms of action of the novel γ-aminobutyric acid receptor antagonist ectoparasiticides fluralaner (A1443) and fipronil | journal = Pest Management Science | volume = 71 | issue = 1 | pages = 91–95 | date = January 2015 | pmid = 24591229 | doi = 10.1002/ps.3768 }}
