Emamectin Benzoate is a semi-synthetic antiparasitic drug derived from avermectin, widely used in veterinary medicine—especially aquaculture—to treat sea lice infestations in salmon and trout. It works by modulating glutamate-gated chloride channels, causing paralysis in parasites. Administered via medicated feed, it offers high efficacy and low toxicity at therapeutic doses.
