Resumen

La piperazina es un antihelmíntico de espectro reducido utilizado principalmente para el tratamiento de ​áscaris (gusanos redondos)​ en perros, gatos, caballos, cerdos y aves de corral.

  • Se considera seguro su uso en animales con gastroenteritis concurrente y durante la gestación.
  • Perla clínica: Debido a que la piperazina solo es eficaz contra áscaris adultos y carece de eficacia contra anquilostomas, tricocéfalos o tenias, su uso en la medicina veterinaria moderna ha sido reemplazado en gran medida por antihelmínticos de espectro más amplio como el pyrantel, fenbendazol y las lactonas macrocíclicas.
  • Disponible en varias formas de sal (citrato, adipato, fosfato, hexahidrato, dihidrocloruro), las cuales contienen cantidades variables de la base activa de piperazina.

Mecanismo de acción

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.

Seguridad y advertencias

Contraindicaciones

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

Efectos adversos

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

Precauciones

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.

Interacciones farmacológicas

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

Monitorización

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

Farmacocinética

Absorción

Readily absorbed from the proximal sections of the gastrointestinal tract.

Distribución

Specific distribution kinetics on individual species were not located.

Metabolismo

Metabolized by the kidneys.

Eliminación

Excreted by the kidneys.

Sobredosis

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.

Información para el cliente

  • Administre exactamente según las indicaciones: Administre solo la cantidad recetada por su veterinario. No exceda la dosis.
  • Generalmente es necesario repetir el tratamiento: Debido a que el medicamento solo elimina los gusanos adultos en los intestinos y no afecta a las larvas migratorias en los tejidos, normalmente se requiere una segunda dosis de 2 a 3 semanas después de la primera.
  • Monitoree los efectos secundarios: Comuníquese con su veterinario de inmediato si nota efectos adversos graves como vómitos, diarrea, debilidad severa, espasmos musculares o caminar descoordinado (ataxia).
