History

Laboratories developed the Biltricide for parasitological research of Bayer AG in Germany (Elberfeld) in the mid 1970s. The World Health Organization includes it on its Model List of Essential Medicines.

Uses

1. Biltricide (CAS NO.55268-74-1) is used to treat Echinococcosis
2.It is used to Cysticercosis (though it has been judged less effective than albendazole in treatment of neurocysticercosis.)
3.It is used to Intestinal tapeworms. In veterinary medicine it is widely used against tapeworms, either alone under the trade name Droncit, or in combination with pyrantel pamoate under the trade name Drontal.
4.It is used against Schistosoma.As of 2005, Biltricide is the primary treatment for human schistosomiasis, for which it is    usually effective in a single dose.
5.It is used to treat liver flukes (such as Clonorchis sinensis) except for fascioliasis.
6.It is also used to treat paragonimiasis.
