Albendazole is a benzimidazole carbamate derivative with activity against most nematodes and some other worms. Albendazole is thought to inhibit cytoplasmic microtubules in the worm's intestinal tract leading to decreased glucose uptake and depletion of glycogen stores in the worm. Three 400 mg doses of albendazole has efficacy against whipworm, hookworm and roundworm infections, all of which we expect to be prevalent in this cohort. A recent randomized controlled trial of various albendazole dosing regimens showed that a single 400mg dose of albendazole was associated with a significantly lower rate of cure (23%) compared to a three day regimen (67%). In this study, reduction in the number of eggs/gm of feces with a single 400mg dose was 96.8% compared to 99.7% with the three day regimen. Albendazole is minimally absorbed from the gastrointestinal tract and has minimal side-effects.
