Extinosad

Extinosad Uses, Dosage, Side Effects, Food Interaction and all others data.

Extinosad is a pediculicide mixture of spinosyn A and spinosyn D (in an approximately 5:1 ratio, respectively) used in the topical treatment of head lice in children (four years old and older) and in adults. Extinosad is an insecticide based on a compound found in S. spinosa, a bacterial species. Extinosad has also been experimented for use in cats for treatment of flea infestations, and has also been experimented for use against the KS1 Ctenocephalides felis flea strain infesting dogs, in addition to many investigations for use in other animals and agricultural plants.

Spinosyn A does not appear to directly interact with any known relevant insecticidal targets, but instead boasts a novel mechanism that resembles a GABA antagonist. Spinosyn A is also slightly more biologically active than spinosyn D.

How Extinosad works

Extinosad is a mixture of spinosyn A and spinosyn D in a 5:1 ratio. This combination causes neuronal hyperexcitation through mostly alteration of nicotinic acetylcholine receptors, which ultimately leads to lice paralysis and death.

Toxicity

Natroba contains benzyl alcohol, which should be avoided in neonates due to associated severe adverse effects and potential fatality. For use only on the scalp and associated hair. Avoid ingestion and contact with eyes. Extinosad itself is not hazardous by the oral, dermal, ocular, or inhalational routes.
