PYRETHRIN 2 Chemical Properties, Uses, Production

Uses

Insecticide.

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.

Definition

ChEBI: Pyrethrin II is a member of pyrethrins. It is functionally related to a pyrethrin I.

Safety Profile

Poison experimentally by ingestion and intravenous routes. Moderately toxic to humans by unspecified route. An allergen. When heated to decomposition it emits acrid smoke and irritating fumes. An insecticide. See also other pyrethrin entries.
