Fluralaner
Fluralaner is a systemic **isoxazoline** ectoparasiticide used primarily for the treatment and prevention of flea and tick infestations in dogs and cats. It provides an extended duration of action, typically lasting up to 12 weeks per dose. > **Clinical Pearl:** The oral chewable formulation for dogs must be administered with food to maximize gastrointestinal absorption. Use with caution in animals with a known history of seizures or neurologic disorders.
กลไกการออกฤทธิ์: Fluralaner acts as an ectoparasiticide by antagonizing ligand-gated chloride channels. It specifically targets channels gated by the neurotransmitter **gamma-aminobutyric acid (GABA)** and glutamate (GluCl) → blocks pre- and post-synaptic transfer of chloride ions across cell membranes → results in uncontrolled central nervous system activity and death of insects and acarines.
