概覽

哌嗪是一種窄效驅蟲藥，主要用於治療狗、貓、馬、豬和家禽的​蛔蟲​感染。

  • 在患有胃腸炎或懷孕的動物中使用被認為是安全的。
  • ​臨床提示​：由於哌嗪僅對成蟲有效，且對鉤蟲、鞭蟲或絛蟲無效，隨著新型廣效驅蟲藥（如雙羥萘酸噻嘧啶、芬苯達唑和大環內酯類）的出現，其在現代獸醫學中的使用已大幅減少。
  • 市面上有各種鹽類形式（檸檬酸鹽、己二酸鹽、磷酸鹽、六水合物、二鹽酸鹽），其中含有不同量的哌嗪活性基質。

作用機轉

Piperazine exerts a ​'curare-like' effect​ on susceptible nematodes.

  • It acts as a GABA receptor agonist and blocks acetylcholine at the myoneural junction of the parasite.
  • This causes flaccid paralysis (narcotizing the worm), allowing the live, paralyzed worms to be passed out of the host's gastrointestinal tract with the feces.
  • In ascarids, it also inhibits succinic acid production.

安全性與警告

禁忌症

  • Chronic liver disease
  • Chronic kidney disease
  • Gastrointestinal hypomotility
  • Chronic renal failure
  • Hepatic impairment
  • Heavy worm burdens (relative contraindication due to risk of intestinal impaction)

不良反應

  • Diarrhea
  • Emesis
  • Transient softening of feces (horses)
  • Neurological signs at high doses (ataxia, tremors)

注意事項

Important: Use with caution in patients with seizure disorders.

Equine Warning: In horses with heavy infestations of Parascaris equorum, rupture or blockage of the intestines is possible due to the rapid death and detachment of a large worm burden.

  • Laboratory Interference: Piperazine can affect uric acid blood levels (both falsely high and low values have been reported); interpret results cautiously.

藥物交互作用

ChlorpromazineModerate

May precipitate seizures if used concomitantly (data conflicts, but caution is advised)

Laxatives (Purgatives)

Not recommended; may eliminate piperazine from the GI tract before its full efficacy is established

Pyrantel / Morantel

Antagonistic modes of action (pyrantel causes spastic paralysis, piperazine causes flaccid paralysis); should not be used together

PyrantelMajor

Antagonistic mechanism of action (Pyrantel causes spastic paralysis, Piperazine causes flaccid paralysis)

MorantelMajor

Antagonistic mechanism of action

監測

  • Clinical and/or laboratory efficacy (fecal examinations)
  • Adverse effects (neurological signs, GI upset)
  • Fecal flotation (to confirm clearance of roundworms)
  • Adverse neurological signs

藥物動力學

吸收

Readily absorbed from the proximal sections of the gastrointestinal tract.

分佈

Specific distribution kinetics on individual species were not located.

代謝

Metabolized by the kidneys.

排除

Excreted by the kidneys.

過量

Piperazine generally has a wide margin of safety (oral LD50 of piperazine adipate in mice is 11.4 g/kg). However, acute massive overdosage can lead to paralysis and death.

​Feline Toxicity:​ In cats, adverse effects occur within 24 hours after a toxic dose is ingested. Clinical signs include:

  • Emesis, hypersalivation, dehydration
  • Weakness, dyspnea, depression
  • Muscular fasciculations of ears, whiskers, tail, and eyes
  • Rear limb ataxia, head-pressing
  • Positional nystagmus and slowed pupillary responses ​(Many of these effects may also be seen in dogs after toxic ingestions.)​

​Treatment:​

  • Symptomatic and supportive care.
  • If ingestion was recent, use of activated charcoal and a cathartic is suggested.
  • Intravenous fluid therapy.
  • Keep the animal in a quiet, dark place.
  • Recovery generally takes place within 3-4 days.

儲存與穩定性

Unless otherwise specified by the manufacturer, piperazine products should be stored at room temperature (15-30°C).

飼主須知

  • ​嚴格按照指示給藥​：請僅給予獸醫處方的劑量，切勿過量。
  • ​通常需要再次治療​：由於藥物只能殺死腸道內的成蟲，對組織中遷移的幼蟲無效，因此通常需要在首次給藥後 2 到 3 週進行第二次給藥。
  • ​監測副作用​：如果您發現任何嚴重的副作用，如嘔吐、腹瀉、嚴重虛弱、肌肉抽搐或步態不穩（共濟失調），請立即聯繫您的獸醫。
