Triclabendazole for the treatment of fascioliasis and paragonimiasis

Abstract
Fascioliasis and paragonimiasis, which are caused by liver flukes (Fasciola) and lung flukes (Paragonimus), are emerging public health problems. Several hundred millions of people are at risk of the two diseases that cause considerable morbidity and delay socio-economic development. Triclabendazole, a benzimidazole derivative, has been routinely used since 1983 in veterinary medicine to control infections with Fasciola spp. in domestic herbivorous animals. In 1986, a veterinary formulation of triclabendazole was first administered to two human patients with fascioliasis. Clinical data obtained thus far suggest that triclabendazole is the most efficacious and best tolerated drug for the treatment of fascioliasis. Moreover, the drug holds promise as a useful therapeutic alternative to praziquantel in the treatment of paragonimiasis. This review of triclabendazole includes an overview of the pharmacodynamics and pharmacokinetics, toxicology and efficacy against the major food-borne trematodes in laboratory a...
