Virbac Effitix Spot On for Dogs

Effitix spot on contains fipronil and permethrin. Fipronil is an insecticide and acaricide belonging to the phenylpyrazole family. Fipronil and its metabolite fipronil sulfonate act at ligand gated chloride channels, in particular those gated by the neurotransmitter gamma-aminobutyric acid (GABA).

It also acts on channels gated by glutamate (Glu, unique invertebrate ligand-gated chloride channels) both desensitising (D) and non-desensitising (N). Thereby it blocks pre- and post-synaptic transfer of chloride ions across cell membranes which results in death of insects or acari due to uncontrolled activity of the central nervous system.
