Piperazidine: Full Drug Profile

Medically reviewed by Min Clinic Staff | Updated: January 2026

Piperazidine - General Information

Piperazidine is an organic compound that consists of a six-membered ring containing two opposing nitrogen atoms. Piperazidine exists as small alkaline deliquescent crystals with a saline taste.
Piperazidine was introduced to medicine as a solvent for uric acid. When taken into the body the drug is partly oxidized and partly eliminated unchanged. Outside the body, piperazine has a remarkable power to dissolve uric acid and producing a soluble urate, but in clinical experience it has not proved equally successful.
Piperazidine was first introduced as an anthelmintic in 1953. A large number of piperazine compounds have anthelmintic action. Their mode of action is generally by paralysing parasites, which allows the host body to easily remove or expel the invading organism.

 

Pharmacology of Piperazidine

Piperazidine is an anthelminthic especially useful in the treatment of partial intestinal obstruction caused by Ascaris worms, which is a condition primarily seen in children. Piperazidine hydrate and piperazine citrate are the main anthelminthic piperazines.

 

Piperazidine for patients

 

Piperazidine Interactions

Phenothiazines - Taking piperazine and a phenothiazine together may increase the risk of convulsions (seizures).
Pyrantel (e.g., Antiminth) - Taking piperazine and pyrantel together may decrease the effects of piperazine.

 

Piperazidine Contraindications

Patients with hypersensitivity to piperazine salts or a history of renal function impairment should avoid this medication

 

Additional information about Piperazidine

Piperazidine Indication: Used as alternative treatment for ascariasis caused by Ascaris lumbricoides (roundworm) and enterobiasis (oxyuriasis) caused by Enterobius vermicularis (pinworm). It is also used to treat partial intestinal obstruction by the common roundworm, a condition primarily occurring in children. Mechanism Of Action: Piperazidine is a GABA receptor agonist. Piperzine binds directly and selectively to muscle membrane GABA receptors, presumably causing hyperpolarization of nerve endings, resulting in flaccid paralysis of the worm. While the worm is paralyzed, it is dislodged from the intestinal lumen and expelled live from the body by normal intestinal peristalsis.

Symptoms of overdose include muscle fatigue, seizures, and difficulty breathing. Protein Binding: 60-70% Biotransformation: About 25% is metabolized in the liver. Piperazine is nitrosated to form N -mononitrosopiperazine (MNPz) in gastric juice, which is then metabolized to N-nitroso-3-hydroxypyrrolidine (NHPYR).
