Preventef flea collar for dogs

Preventef is recommended to use in dogs for the control and treatment of fleas and ticks

The Preventef line is of flea collar for dogs and cats incorporating in its matrix an organophosphate insecticide called Diazinon.
The mechanism of action of Diazinon is to inhibit acetylcholinesterase, leading to paralysis and death of the parasite.

The insecticide can enter parasite via suction or through the cuticle due to high liposolubility.

Preventef contains essential fatty acids that improves the absorption and diffusion of the drug through the lipid layer of the skin, that helps revitalize the skin and hair; and regenerate the skin in areas of lesions caused by allergy to flea saliva.

Unique for containing the active ingredient in the matrix collar with the fat-soluble vehicle, so that the release becomes slow and controlled (high safety) and not quenched with water (maximum effectiveness).
