| Hazard Information | Back Directory | [Uses]
Insecticide. | [Definition]
ChEBI: Pyrethrin II is a member of pyrethrins. It is functionally related to a pyrethrin I. | [Indications]
Pyrethrin (Licide, R&C, RID, Tisit) compounds and synthetic pyrethroids are used
for the treatment of pediculosis. These are currently the drugs of choice in treating pediculosis. They demonstrate no scabicidal effect. Resistance has
been shown to these compounds. They are absorbed through the chitinous exoskeleton
and stimulate the nervous system, resulting in seizures and death of the insect. |
