5. Pharmacological properties:

ATC Vet code: QP53AC04

5.1 Pharmacodynamic properties:

Permethrin is a contact ectoparasiticide acting on the sodium channel. It attacks the peripheral nervous system and, in particular, the motor nerve terminals in the central nervous system. Broadly speaking, Permethrin causes knockdown in arthropods, inducing loss of co-ordination, spasms, tremors and ultimately death.

When topically administered, the solution will rapidly disperse across the surface of the skin by virtue of the carrier having a relatively low viscosity and a very low vapour pressure. This mobility of the solution, in combinationwith capillary action through the coat and across the skin, together with natural movement of the animal, ensures adequate dispersion. Given that a high flea mortality was achieved one day after topical administration of the solution, this indicates good coverage of the individual animals by the insecticide.

If Permethrin is orally administered to mammals it is rapidly metabolised and almost completely excreted via urine or faeces within a short period of time. The trans isomer is eliminated faster than the cis isomer, it being the more susceptible of the two to esterase attack. The major metabolic reactions are ester hydrolysis, ester cleavage, oxidation and conjugation. Permethrin does not have a tendency to accumulate in tissues. None of the metabolites of Permethrin show a higher acute toxicity than the base Permethrin. Given that this product is administered externally, absorption rates are considerably lower than when orally administered.
