Arbotect - General Information
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)
Pharmacology of Arbotect
Arbotect is a fungicide and parasiticide. Arbotect 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. Arbotect 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). Arbotect also suppresses egg and/or larval production and may inhibit the subsequent development of those eggs or larvae which are passed in the feces.
Arbotect for patients
Because CNS side effects may occur quite frequently, activities requiring mental alertness should be avoided.
Thiabendazole may compete with other drugs, such as theophylline, for sites of metabolism in the liver, thus elevating the serum levels of such compounds to potentially toxic levels. Therefore, when concomitant use of thiabendazole and xanthine derivatives is anticipated, it may be necessary to monitor blood levels and/or reduce the dosage of such compounds. Such concomitant use should be administered under careful medical supervision.
Hypersensitivity to this product.
Thiabendazole is contraindicated as prophylactic treatment for pinworm infestation.

Arbotect Indication: For the treatment of strongyloidiasis (threadworm), cutaneous larva migrans (creeping eruption), visceral larva migrans, and trichinosis.
Mechanism Of Action: The precise mode of action of thiabendazole on the parasite is unknown, but it most likely inhibits the helminth-specific enzyme fumarate reductase.
