์์ฉ ๊ธฐ์ : Selamectin acts by binding to **glutamate-gated chloride channels** in the nervous system of invertebrates. Binding โ increased permeability of the cell membrane to chloride ions โ hyperpolarization of the nerve or muscle cell โ **flaccid paralysis and death** of the parasite. *Clinical Pearl:* Mammals generally lack glutamate-gated chloride channels, and macrocyclic lactones do not readily cross the intact mammalian blood-brain barrier (mediated by P-glycoprotein), conferring a high margin of safety.

Generally very safe. Overdoses up to 10 times the recommended dose typically do not produce clinical signs in dogs or cats. If massive accidental ingestion occurs, monitor for neurologic signs (ataxia, tremors, mydriasis) and provide supportive care.
