Ectoparasiticide
Permethrin
### Permethrin

Broad\-spectrum and potent pyrethroid insecticide and is most convenient for both scabies and lice. First choice drug. Permethrin exerts its therapeutic effect by disrupting sodium transport across neuronal membranes in arthropods, inducing depolarization. This mechanism ultimately leads to respiratory paralysis in the affected arthropod, establishing permethrin as a potent agent in managing scabies and pediculosis.

The above research article, noted from current studies, shows that Permethrin is only 89\.2% effective. There is noted resistance that has been increasing each year, as noted in the article.


Can permethrin be used for other conditions besides scabies and lice?
