洛替拉納
體外寄生蟲驅殺藥 (異噁唑啉類)
洛替拉納是一種屬於異噁唑啉類的全身性體外寄生蟲驅殺藥，用於治療和預防犬貓的跳蚤和壁蝨感染。 **臨床提示：** 異噁唑啉類藥物非常有效且起效迅速，但寄生蟲必須附著並開始吸血才能接觸到有效成分。
作用機制: Lotilaner acts as an antagonist at **gamma-aminobutyric acid (GABA)-gated chloride channels** and, to a lesser extent, **glutamate-gated chloride channels** (GluCls) in insects and acarines. Binding blocks the transfer of chloride ions across cell membranes → uncontrolled neuromuscular activity → paralysis → death of the parasite.
