Ectoparasiticide active against flies and lice.
Arpon is an ectoparasiticidal veterinary medicine active against:
Active substance: Cypermethrin.
Cypermethrin is a contact ectoparasiticide substance from the group of type II pyrethroids, which is characterized by having an alpha-cyan group in its molecule.
Group II pyrethroids mainly affect the Na + channels of nerve membranes, causing an increase in the duration of the transient increase in membrane permeability to Na + during the excitation phase. They keep altering the Na + channels persistently, depolarize the membrane and block the action potential, without causing presynaptic activity.
Posology and route of administration:
