5.1 Pharmacodynamic properties

The product contains fenbendazole which is a member of the benzimidazole family of anthelmintics and has been in veterinary use for a number of years. Fenbendazole acts against helminths by disrupting the formulation of microtubules by binding to tubulin in parasitic intestinal cells hence preventing the absorption of glucose; parasites are gradually starved to death. Fenbendazole displays preference for helminth as opposed to mammalian tubulin; this appears to be due to the fact that the formation of the parasitic tubulin-fenbendazole complex is more favourable kinetically under physiological conditions than for the mammalian tubulin-fenbendazole complex.

5.2 Pharmacokinetic properties

No specific pharmacokinetic studies have been performed with the product.
