Piperazine dihydrochloride appears as white to cream-colored needles or powder. Mp: 318-20°C (with decomposition).|An anti-nematodal agent effective against the intestinal nematodes ASCARIS LUMBRICOIDES (roundworm) and ENTEROBIUS VERMICULARIS (pinworm, threadworm). It produces a neuromuscular block leading to flaccid muscle paralysis in susceptible worms, which are then dislodged from the gut and expelled in feces.
Moderately toxic by intraperitoneal route. Mildly toxic by ingestion. When heated to decomposition it emits very toxic fumes of NOx and HCl. Used in making fiber, pharmaceuticals, and insecticides. See also PIPERAZINE.
Agricultural chemical, Suspected reprotoxic hazard. Piperazine is used to manufacture anthelmintics, antifilarials, antihistamines, and tranquilizers; the dihydrochloride is used in the manufacture of fibers, pharmaceuticals and insecticides. They are used as an intermediate in the manufacture of, pesticides, rubber chemicals and fibers. Also, piperazine is widely available, effective, and safe when used on an occasional basis against ascaride infections. It is also considerably cheaper than other anthelminthic drugs. In some countries where ascariasis is not endemic and where piperazine was used predominantly for the treatment of pinworn, it has been withdrawn from use on the grounds that other effective drugs are now available. Clinical dosages occasionally induce transient neurological signs and, in some circumstances, the drug may generate small amounts of nitrosamine in the stomach, which at considerably greater dosage in experimental animals has been demonstrated to have a carcinogenic potential.
