Use

Permethrin is 3-(2,2-Dichloroethenyl)-2,2-dimethylcyclopropanecarboxylicacid (3-phenoxyphenyl)methylester or 3-(phenoxyphenyl)methyl (±)-cis, trans-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylate(Nix). This synthetic pyrethrinoid compound is more stablechemically than most natural pyrethrins and is at least as activeas an insecticide. Of the four isomers present, the1(R),trans and 1(R),cis-isomers are primarily responsiblefor the insecticidal activity. The commercial product is amixture consisting of 60% trans and 40% cis racemic isomers.It occurs as colorless to pale yellow low-melting crystalsor as a pale yellow liquid and is insoluble in water butsoluble in most organic solvents.Permethrin exerts a lethal action against lice, ticks, mites,and fleas. It acts on the nerve cell membranes of the parasitesto disrupt sodium channel conductance. It is used as apediculicide for the treatment of head lice. A single applicationof a 1% solution effects cures in more than 99% ofcases. The most frequent side effect is pruritus, which occurredin about 6% of the patients tested.
