Used as an anthelmintic agent to treat parasitic worm infections, particularly pinworm (Enterobius vermicularis) and roundworm (Ascaris lumbricoides) infestations. It works by paralyzing the worms, allowing the body to expel them naturally via the intestines. Commonly formulated in pediatric antiparasitic medications due to its favorable safety profile in children. Also utilized in combination therapies for broader spectrum deworming activity. Piperazine citrate hydrate is a specialty chemical primarily employed as a pharmaceutical intermediate and active ingredient in anthelmintic formulations.
