Permethrin is a widely-used pesticide of the pyrethroid family. Permethrin interacts with voltage-gated Na+ channels and

inhibits their natural deactivation, causing the channels to remain open for a long time and destroying equilibrium of the

neuronal system. Pyrethroids are also thought to interact with GABA receptors and associated pathways.
