Febentel 150mg Tablets FEBENTEL 150 MG contains Fenbendazole, a broad-spectrum benzimidazole anthelmintic. It acts by binding to parasite tubulin, inhibiting microtubule polymerization and cell division during parasite mitosis, while simultaneously disrupting glucose absorption and energy metabolism in susceptible parasites. This depletion of energy reserves leads to paralysis, disruption of structural integrity, and mortality of the helminths. FEBENTEL 150 MG is indicated as a dewormer for the management and control of gastrointestinal parasites, including roundworms, hookworms, whipworms, and tapeworms.
