• Drug Groups: approved
• Description: 2-Substituted benzimidazole first introduced in 1962. It is active against a variety of nematodes and is the drug of choice for strongyloidiasis. It has CNS side effects and hepatototoxic potential. (From Smith and Reynard, Textbook of Pharmacology, 1992, p919)
• Indication: For the treatment of strongyloidiasis (threadworm), cutaneous larva migrans (creeping eruption), visceral larva migrans, and trichinosis.
• Pharmacology: Thiabendazole is a fungicide and parasiticide. Thiabendazole is also a chelating agent, which means that it is used medicinally to bind metals in cases of metal poisoning, such as lead poisoning, mercury poisoning or antimony poisoning. Thiabendazole is vermicidal and/or vermifugal against Ascaris lumbricoides ("common roundworm"), Strongyloides stercoralis (threadworm), Necator americanus, Ancylostoma duodenale (hookworm), Trichuris trichiura (whipworm), Ancylostoma braziliense (dog and cat hookworm), Toxocara canis, Toxocara cati (ascarids), and Enterobius vermicularis (pinworm). Thiabendazole also suppresses egg and/or larval production and may inhibit the subsequent development of those eggs or larvae which are passed in the feces.
• Toxicity: Overdosage may be associated with transient disturbances of vision and psychic alterations. The oral LD 50 is 3.6 g/kg, 3.1 g/kg and 3.8 g/kg in the mouse, rat, and rabbit respectively.
• Affected Organisms: Roundworms, hookworms, and other helminth species
• Biotransformation: Hepatic. Metabolized almost completely to the 5-hydroxy form which appears in the urine as glucuronide or sulfate conjugates.
• Absorption: Rapidly 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.
• 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).
• Elimination: It is metabolized almost completely to the 5-hydroxy form which appears in the urine as glucuronide or sulfate conjugates.

Drug information: experimental

Selleck Chemicals - S1739

Research Area: Infection
Biological Activity:
Thiabendazole inhibites the mitochondrial helminth-specific enzyme, fumarate reductase, with possible interaction with endogenous quinone. [1]A benzimidazole derivative with anthelminthic property. Thiabendazole inhibits the helminth-specific mitochondrial enzyme fumarate reductase, thereby inhibiting the citric acid cycle, mitochondrial respiration and subsequent production of ATP, ultimately leading to helminth’s death. [2]

Sigma Aldrich - T8904

Application
Thiabendazole (TBZ) is a broad-spectrum antihelminthic and is used to treat parasitic infections in humans. It is used as an agricultural fungicide and as a food preservative1. Thiabendazole has been used as a heavy metal chelating detoxification agent. It is used clinically to treat threadworm, cutaneous larva migrans, visceral larva migrans, and trichinosis2.
Biochem/physiol Actions
Thiabendazole inhibits anaerobic respiration at the level of mitochondrial helminth-specific enzyme. It acts as a quinol-fumarate reductase (QFR) inhibitor in ,C. jejuni and H. pylori, blocking quinol oxidation to quinone. Thiabendazole suppresses egg and larval production and may inhibit the subsequent development of eggs and larvae which are passed in feces2. A proposed route of biotransformation of thiabendazole is the CYP1A2-catalyzed hydroxylation to 5-hydroxythiabendazole, which is metabolized to glucuronide and sulfate conjugates1.
