Eprinomectin B1a

Description:

Eprinomectin B1a is a macrocyclic lactone compound belonging to the avermectin family, primarily used as an antiparasitic agent in veterinary medicine. It is derived from the fermentation of the bacterium Streptomyces avermitilis and is known for its efficacy against a broad spectrum of parasites, including nematodes and ectoparasites. Eprinomectin B1a exhibits a high degree of lipophilicity, which enhances its absorption and distribution in animal tissues. Its mechanism of action involves binding to glutamate-gated chloride channels, leading to paralysis and death of the parasites. This compound is notable for its low toxicity to mammals, making it a preferred choice for use in livestock. Additionally, Eprinomectin B1a is characterized by its stability and long half-life, allowing for effective control of parasitic infections with fewer doses. It is also used in various formulations, including pour-on solutions and injectable forms, to facilitate ease of administration in animals. Overall, Eprinomectin B1a is a vital tool in veterinary parasitology, contributing to animal health and productivity.
