Fenbendazole

Fenbendazole is a benzimidazole anti-parasitic/anti-helminthic that is used in veterinary medicine to treat infections of Giardia, Strongyloides, and various worms. Fenbendazole binds fungal tubulin, preventing microtubule polymerization and inhibiting hyphal growth and nuclear division.
