Praziquantel

Praziquantel

Praziquantel is the gold standard veterinary isoquinoline anthelmintic specifically engineered for the elimination of cestodes (tapeworms) and trematodes (flukes). It exhibits exceptional efficacy against a wide range of parasitic worms, including Dipylidium caninum (common flea tapeworm), Taenia species, and the highly zoonotic Echinococcus granulosus (hydatid tapeworm). Unlike many dewormers that merely paralyze parasites, Praziquantel damages the parasite's tegument (skin), causing rapid paralysis and subsequent digestion by the host's immune system. This broad-spectrum cestocide is a critical component in canine and feline deworming programs, equine health management, and aquaculture (for treating skin flukes). Available as oral tablets, injectable solutions, and topical spot-ons, Praziquantel provides a reliable, single-dose solution for tapeworm control and the prevention of zoonotic diseases.
