Praziquantel is an anthelmintic effective against flatworms. It is used against Schistosoma. As of 2005, praziquantel is the primary treatment for human schistosomiasis, for which it is usually effective in a single dose. It is also used to treat liver flukes such as Clonorchis sinensis, and against fascioliasis. In veterinary medicine it is widely used against tapeworms, either alone or in combination with pyrantel pamoate.
