Febantel, a new broad-spectrum anthelminthic

Area of Science:

• Veterinary Pharmacology
• Parasitology
• Drug Discovery

Background:

• Parasitic infections caused by nematodes and cestodes pose significant health and economic challenges in livestock and companion animals.
• Development of novel, effective, and well-tolerated anthelmintic agents is crucial for animal health management.

Purpose of the Study:

• To evaluate the anthelmintic activity of a new compound, N-(2-[2,3-Bis-(methoxycarbonyl)-guanidino]-5-(phenylthio)-phenyl)-2-methoxyacetamide (febantel, Rintal).
• To assess the efficacy and tolerability of febantel in various animal models and in sheep and cattle.

Main Methods:

• In vivo testing of febantel against nematode and cestode species in laboratory animals (mice, rats) and domestic animals (dogs, sheep, cattle).
• Administration of a single oral dose of 5 mg/kg febantel to sheep and cattle.
• Monitoring for parasitic elimination and assessment of animal tolerability.

Main Results:

• Febantel exhibited high activity against a broad spectrum of nematodes and cestodes in mice and rats.
• A single oral dose of 5 mg/kg febantel in sheep and cattle led to near-complete elimination of intestinal nematodes (larval and adult) and Dictyocaulus.
• The compound demonstrated good tolerability across all tested animal species.

Conclusions:

• Febantel is a highly effective and well-tolerated anthelmintic agent.
• Its broad-spectrum activity and efficacy in livestock make it a valuable new option for parasitic disease control.
