Pharmacology: Permethrin is a broad spectrum antiparasitic against mites, head lice, body lice and other arthropods.
Permethrin works by interfering with the polarization of the parasite's nerve cell wall by binding to sodium. This slows down the repolarization of the cell wall and eventually paralysis occurs.
Permethrin is rapidly metabolized in the skin. The inactive result of metabolism will soon be excreted through the urine.
