Tigolaner（Cat No.:I015393）is a novel ectoparasiticide belonging to the isoxazoline class, developed for veterinary use to protect companion animals against external parasites. It acts by selectively inhibiting ligand-gated chloride channels, such as GABA- and glutamate-gated channels, in arthropods, leading to uncontrolled neuronal activity and parasite death. Tigolaner demonstrates broad-spectrum activity against fleas and ticks, providing effective and long-lasting protection. With favorable safety and pharmacokinetic properties in animals, Tigolaner is a valuable tool in veterinary medicine for improving parasite control and enhancing animal health and welfare.
