🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Permethrin, the active ingredient in this medicine, is a synthetic pyrethroid that acts on the nervous system of parasites. It binds to voltage-gated sodium channels in the nerve cells of mites and lice, prolonging the opening of these channels. This leads to continuous depolarization of the nerve membrane, causing hyperexcitation, paralysis, and eventually death of the parasite. Permethrin has low toxicity to humans because it is poorly absorbed through intact skin and is rapidly metabolized by esterases in the skin and liver.
