Overview of Nitroscanate for Canines

  •  Nitroscanate, also known as Lopatol®, is a prescription drug used for dogs to roundworm, hookworm, tapeworm and fluke. 
  • Due to the large number and variety of parasites that can infect pets, the control of parasitic diseases often requires the use of multiple drugs. Most of the drugs commonly used to treat or control common nematode intestinal worms and heartworms are ineffective in the control of tapeworms (parasites belonging to the class Cestodes). Nitroscanate is a parasite-control drug with strong activity against a number of different tapeworms, as well as against flukes, hookworms, and roundworms.
  • The most common tapeworms of dogs and cats (Dipylidium) are spread from pet to pet by fleas. Less common tapeworms (Taenia and Echinococcus) are found in animals that hunt and ingest parasite hosts, such as rabbits, which carry these worms.
  • Nitroscanate is a prescription drug and can only be obtained from a veterinarian or by prescription from a veterinarian.
