Ivermectin enhances the release of gamma amino butyric acid (GABA) at presynaptic neurons. GABA acts as an inhibitory neurotransmitter and blocks the post-synaptic stimulation of the adjacent neuron in nematodes or the muscle fiber in arthropods. By stimulating the release of GABA, ivermectin causes paralysis of the parasite and eventual death. 

Toxicity may occur at high doses and in breeds in which ivermectin crosses the
blood–brain barrier.

Sensitive breeds include collies, Australian shepherds, Old
English sheepdogs, longhaired whippets, and Shetland sheepdogs. 

Toxicity is neurotoxic and signs include hypersalivation, depression, ataxia, difficulty with
vision, coma, and death.
