Biological Activity

[Description]:

Afoxolaner is an orally active isoxazoline insecticide/acaricide against Ixodes scapularis in dogs. Afoxolaner acts on the insect γ-aminobutyric acid receptor (GABA) and glutamate receptors, inhibiting GABA & glutamate-regulated uptake of chloride ions, resulting in excess neuronal stimulation and death of the arthropod[1][2].

Signaling Pathways >> Membrane Transporter/Ion Channel >> GABA Receptor
Signaling Pathways >> Neuronal Signaling >> GABA Receptor

[In Vivo]

A single oral treatment with a dose approaching the minimum effective dose of afoxolaner (2.5mg/kg) eliminated the pre-existing infestations of I. scapularis ticks and controlled weekly re-infestations, with efficacy between 98% and 100% recorded until Day 23 and 94% at Day 30[1].
