Antiparasitos collar for dogs of all sizes Preventef

Effective parasite necklace especially designed for use in dogs. It is effective for the prevention and treatment of the external parásitosis produced dogs for fleas and ticks. This necklace features fatty acids also provided hair brighter and force. It is effective for 4 months. Manufactured by Virbac laboratory.

The Preventef ® line is composed of anti-parasitic collars for dogs that incorporate in their matrix an organophosphate insecticide called Diazinon, whose mechanism of action is to inhibit acetylcholinesterase. The insecticide can join the parasite by suction or through the cuticle due to its high solubility.

In the nerve Synapse a nerve impulse is transmitted by acetylcholine (Ach), once transmitted the message, Ach is destroyed by the action of an enzyme called acetylcholinesterase, so that the momentum is annulled for another transmission.

To cancel the action of Ach, the transmission of nerve impulses can not be interrupted and the muscle contraction leads to paralysis and death of the parasite.

Only insects possess cholinergic synapses in the central nervous system, so the signs in the insects are hiperexcitabilidad, convulsions, paralysis and eventually death.

Preventef ® added with essential fatty acids enhances the absorption and diffusion of the drug by the lipid layer of the skin, helps the skin and hair conditioning; and to regenerate the skin in areas of lesions caused by allergy to flea saliva.

Only contain the active ingredient in the matrix of the necklace with the liposoluble vehicle, so the release becomes slow and controlled (maximum security) and not inactive with water (maximum effectiveness).
