How Fenbendazole Works
Fenbendazole works by targeting the parasite’s internal cellular structure. It binds to tubulin, a protein required for forming microtubules that are essential for parasite survival.
By disrupting this process, fenbendazole:
- Blocks glucose absorption
- Depletes parasite energy reserves
- Leads to immobilisation and gradual elimination
This selective mechanism allows Fenbendazole Wormentel 150 mg to be effective against parasites while remaining relatively well tolerated in animals when used correctly.
