Eprinomectin is a mixture of eprinomectins B1a and B1b in a 9:1 ratio, produced from a mixture of avermectin B1a and B1b. Eprinomectin is used commercially as a topical endectocide (insecticide, miticide and nematocide) for cattle, including lactating dairy cows. Like all avermectins and milbemycins, eprinomectin acts by binding to parasite glutamate-gated chloride ion channels and disrupts neurotransmission leading to paralysis and death of the parasite, mite or insect.
Function
It is not only a broad spectrum and the most efficacious pesticide of Avermectin kind, but also one of the lowest distribution coefficient of this kind in milk. Trials show that the product with the concentration of 0.1mg/kg or 0.05mg/kg can efficaciously prevent seven kinds of nematodes parasitic on large intestine, small intestine and stomach of cattle and sheep, the efficacy is shown as at least 97%. When it is used to cow in milk, concentration ratio in milk to in plasma is not more than 0.2. It has the advantage over other drugs against nematodes parasitic on cow during milking.
