Piperazine

A ring compound with two nitrogen atoms, first synthesised in the late 19th century and used since the 20th century as an anthelmintic against intestinal roundworms in humans and animals; its ring is also the core of many drugs. This family brings together the active ingredient, pharmacopoeial impurities, labelled standards, nitrosamines and other impurities.

Did you know?It does not kill the worms: by mimicking the neurotransmitter GABA it reversibly paralyses their muscles, so the parasites lose their grip on the gut wall and are expelled.
