Description and Uses
Eprinomectin is a semisynthetic avermectin that consists of a mixture of two homologues, eprinomectin B1a (4 epi-acetylamino-4 -deoxy-avermectin B1; 90%) and eprinomectin B1b (10%).Eprinomectin was developed as a topical endectocide for all categories of cattle including lactating dairy cattle, and the process by which eprinomectin was selected for further development has been described (90). Briefly, several hundred avermectin/ milbemycin analogues were screened in a sheep model for efficacy against a range of endoparasites and in lactating dairy cows for a low milk:plasma partitioning ratio. Themilk:plasma ratio for eprinomectin is <0.2; ivermectin, by comparison, partitions equally between milk and plasma.
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.
