Abstract

Background: Parasitic infections are widespread in sheep farms of the Russian Federation, including Siberia. The infection of sheep with helminths and parasitic arthropods with a range of 70% to 100% in different regions, contributes to a decrease in the productivity and quality of products, and even death of animals. This study aimed to formulate drugs with pronounced parasiticidal effects based on ivermectin and albendazole, widely used to treat animal entomoses and helminth infections.

Methods: New formulations in the form of solid dispersed compositions were prepared by mechanochemical modification of ivermectin and albendazole using arabinogalactan polysaccharide. The efficacy of preparations on gastrointestinal strongylosis and monieziosis, and melophagosis of sheep was determined by parasitological examination and analysis of feces and urine.

Results: The new formulations demonstrated increased solubility and parasiticidal activity due to the formation of inclusion complexes when interact with water. The maximum efficacy values (> 95% efficiency) against intestinal Strongylida and Moniezia expansa, and ectoparasitic Melophagus ovinus were seen in doses lower than the recommended doses of the starting drugs.

Conclusion: The increased parasiticidal activity of innovative compositions can be explained by increased water solubility and bioavailability of the preparations, due to formation of inclusion complexes. The results of this study suggests the possibility of a significant reduction in the dosages of composed substances without losing their parasiticidal activity.
