What is Selamectin?
Selamectin is a semi-synthetic avermectin antiparasitic compound derived from doramectin. It is widely used in veterinary medicine for the prevention and treatment of parasitic infections in animals, particularly dogs and cats. Selamectin acts by enhancing chloride ion permeability in parasite nerve and muscle cells, leading to paralysis and death of the parasites. It provides broad-spectrum protection against fleas, ear mites, heartworm, and certain intestinal worms, making it a key ingredient in topical antiparasitic formulations.
