Permethrin
Introduction
What is Permethrin?
Permethrin is a man-made substance commonly used to control insects and mites and repel bugs. It falls under the category of pyrethroids. Imitates natural compounds found in chrysanthemum flowers.
Historical Context and Development
Permethrin has a history dating back to the 1970s when it was developed as a more efficient option compared to pyrethrins. Its introduction brought about progress in the field of pest control with uses in medical and agricultural settings.
Chemical Properties and Classification
Permethrin is chemically unique, due, to its ester bond. It is classified as a type I pyrethroid. Unlike categories, it doesn't contain the cyano group, which leads to neurotoxic effects. Its ability to adhere well to its targets and deliver lasting results can be attributed to its nature.
Uses of Permethrin
Therapeutic Uses
Permethrin is a synthetic pyrethroid that has been used to treat scabies and head lice 12. It is effective against the mite Sarcoptes scabiei, which causes scabies, and Pediculus humanus capitis, the causative agent of head lice 12. Permethrin works by disrupting the nervous system of the parasites, leading to their death 3.
