Overview
Albendazole is a benzimidazole-derived anthelmintic widely used in veterinary medicine. It effectively controls infections caused by roundworms, tapeworms, and flukes in animals such as cattle, sheep, pigs, and poultry.
It works by disrupting the energy metabolism of parasites, leading to immobilization and death.
Albendazole is one of the most commonly used APIs in the formulation of deworming suspensions, tablets, and feed premixes.
The product is sourced from qualified manufacturers with stable quality and full export documentation support, suitable for pharmaceutical and feed additive applications.
