- Hookworm (Ancylostoma, Necator)
- Roundworm (Ascaris lumbricoides)

Description:
Ben-A is a benzimidazole anthelmintic effective against various nematodes and some cestodes. It is primarily used for intestinal worm infections and higher doses are prescribed for hydatid disease.
- It has vermicide, ovicidal, and larvicidal properties.
- It works by inhibiting tubulin polymerization, leading to the disruption of cytoplasmic microtubules, which are essential for parasite survival.
Pharmacology:
Albendazole is a broad-spectrum anthelmintic with activity against worms at multiple stages of development.
- It works by blocking glucose uptake in parasites, causing energy depletion and eventual immobilization.
- The drug undergoes extensive metabolism in the liver and has a primary metabolite, albendazole sulphoxide, which has anthelmintic properties.
- The plasma half-life of albendazole sulphoxide is approximately 8.5 hours.
- It is poorly absorbed in the gastrointestinal tract and is primarily excreted in the urine.
Dosage & Administration:
For Adults & Children Over 2 Years:
- Single-dose treatment (for Enterobius, Trichuris, Ascaris, Ancylostoma, Necator): 400 mg (1 tablet or 10 ml suspension).
