概覽

地可喹酯(Decoquinate)是一種​4-羥基喹諾酮​類抗原蟲藥,主要在畜禽中作為​抗球蟲藥​使用。雖然它能透過在子孢子階段阻斷寄生蟲的生命週期來有效​預防​球蟲病,但它​對成蟲無效​,無法治療活躍的臨床感染。

在小動物臨床上,最著名的標示外用途是用於狗,在初步急性治療後長期預防​美洲肝簇蟲(Hepatozoon americanum)​的復發。由於它是一種抑菌劑(抑制球蟲而非殺滅球蟲),因此需要依賴宿主的免疫系統來清除被抑制的寄生蟲。

作用機轉

Decoquinate acts specifically on the sporozoite stage of the coccidian life cycle.

  • Sporozoites can still penetrate host intestinal cells, but further intracellular development is halted.
  • Mechanism: It disrupts electron transport within the mitochondrial cytochrome system of the parasite → inhibits respiration and ATP energy production → prevents maturation and replication.

安全性與警告

禁忌症

  • Lactating dairy animals producing milk for food
  • Laying chickens
  • Treatment of active/clinical coccidiosis

注意事項

Decoquinate is not effective for treating clinical coccidiosis and has no efficacy against adult coccidia. It is not FDA-approved for use in animals producing milk for food or in laying chickens.

監測

  • Clinical signs of coccidiosis or hepatozoonosis relapse
  • Muscle biopsy (after 2 years of hepatozoonosis treatment in dogs to confirm clearance)

過量

Decoquinate is considered to have a wide safety margin. No specific acute toxicity information was located.

飼主須知

  • ​給藥方式​:請將藥物與寵物的食物充分混合均勻。
  • ​療程長度非常重要​
    • 用於​預防球蟲病​時,必須至少連續使用 ​4週​
    • 用於治療犬隻​肝簇蟲病​時,這是一個長期的療程,可能需要持續給藥長達 ​2年​ 以防止復發。

​重要提示​:此藥物主要用於預防感染,無法治癒已經出現症狀的活躍性球蟲感染。
