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. 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 . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid
