Lotilaner is a parasiticide, acts as a potent non-competitive antagonist of insects GABACl receptors, with an IC50 of 23.84 nM for Drosophila melanogaster GABA receptor. No effect on a dog GABAA receptor[1].
Lotilaner shows IC50s of 38.25 ± 3.75, 52.40 ± 4.54, 36.79 ± 4.39 nM for Drosophila melanogaster dieldrin/fipronil-resistant forms (DmR2), Lepeophtheirus salmonis (Ls) and Rhipicephalus microplus (Rm) GABACl receptors, respectively[1].
