์์ฉ ๊ธฐ์ : Nitenpyram acts as an agonist at **insect-specific nicotinic acetylcholine receptors (nAChRs)**. * Ingestion by flea via blood meal โ Binds to **alpha-4-beta-2 nicotinic receptors** on postsynaptic membranes โ Blocks acetylcholine-mediated neuronal transmission โ Continuous nerve firing โ **Spastic paralysis and rapid death** of the insect. * It is highly selective (3500 times more selective for insect receptors than vertebrate receptors) and does *not* inhibit acetylcholinesterase, contributing to its exceptionally high safety margin in mammals.

Nitenpyram is relatively safe in high dosages to mammals. * The oral LD50 in rats is approximately 1.6 grams/kg. * Cats or dogs given 10 times the usual dose for 14 days showed no untoward effects. * In the circumstance of a massive overdose, contact an animal poison control center for additional guidance.
