ClassSmall Molecule
DescriptionThiabendazole is a fungicide and parasiticide. It is used primarily to control mold, blight, and other fungally caused diseases in fruits (e.g. oranges) and vegetables; it is also used as a prophylactic treatment for Dutch elm disease. As an antiparasitic, it is able to control roundworms (such as those causing strongyloidiasis), hookworms, and other helminth species which attack wild animals, livestock and humans.

Toxicity Profile
Route of ExposureRapidly absorbed and peak plasma concentration is reached within 1 to 2 hours after the oral administration of a suspension. Some systemic absorption may occur from topical preparations applied to the skin.
Mechanism of ToxicityThe precise mode of action of thiabendazole on the parasite is unknown, but it most likely inhibits the helminth-specific enzyme fumarate reductase.
MetabolismHepatic. Metabolized almost completely to the 5-hydroxy form which appears in the urine as glucuronide or sulfate conjugates. Route of Elimination: It is metabolized almost completely to the 5-hydroxy form which appears in the urine as glucuronide or sulfate conjugates. Half Life: The half-life for thiabendazole in both normal and anephric patients is 1.2 hours (range 0.9 to 2 hours). The half-life for the 5-hydroxythiabendazole metabolite in both normal and anephric patients is 1.7 hours (range 1.4 to 2 hours).
Toxicity ValuesThe oral LD 50 is 3.6 g/kg, 3.1 g/kg and 3.8 g/kg in the mouse, rat, and rabbit respectively.
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesFor the treatment of strongyloidiasis (threadworm), cutaneous larva migrans (creeping eruption), visceral larva migrans, and trichinosis.
