Assessing the effectiveness of fenbendazole supramolecular complexes against schistosomiasis, monieziosis and parabronemosis in sheep.

Helminth infections pose a significant economic threat to livestock production, causing productivity declines and, in severe cases, mortality. Conventional anthelmintics, exemplified by fenbendazole, face challenges related to low solubility and the necessity for high doses. This study explores the potential of supramolecular complexes, created through mechanochemical modifications, to address these limitations.

Synthesis and Clinical Examination of Novel Formulations of Ivermectin, Albendazole and Niclosamide for the Treatment of Equine Gastrointestinal Helminthoses.

Background: This study aimed to develop new complex preparations of ivermectin, niclosamide and albendazole based on solid-phase mechanochemical technology, and to evaluate their efficacy against equine nematodosis and cestodosis.

Methods: Novel formulation of antiparasitic paste were prepared using joint mechano-chemical treatment of ivermectin (0.2 mg/kg bodyweight; BW), niclosamide (10 mg/kg BW) and albendazole (3, 5, 10 mg/kg BW) substances with polyvinylpyrrolidone and arabinogalactan.

Efficacy of Novel Formulations of Ivermectin and Albendazole in Parasitic Infections of Sheep in the Altai Mountains of Russia.

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.

Pharmacokinetic profile, tissue residue depletion and anthelmintic efficacy of supramolecular fenbendazole.

A supramolecular complex of fenbendazole (SFBZ) with polyvinylpyrrolidone (PVP) was created by mechanochemical processing to increase its anthelmintic efficacy and to reduce the dose of applied drugs. The aim of our research was to study the pharmacokinetic profile and tissue residue depletion of fenbendazole (FBZ) and its metabolites: sulfoxide and sulfone in sheep after SFBZ treatment by high-performance liquid chromatography with tandem mass spectrometric detection and to evaluate its efficacy against gastrointestinal strongylatosis of sheep in field trials. The results revealed that FBZ and its metabolites were detected in blood serum in 2 h after SFBZ administration and in 4-6 h after the administration of the basic - FBZ.

Innovative anthelmintic based on mechanochemical technology and their efficacy against parasitic infection of sheeps.

Objective: Solubility and bioavailability are crucial for maximizing the activity of an antiparasitic drug. This study aimed to develop a combined preparation for antiparasitic medicines using ivermectin (Iver), fenbendazole (FBZ), and triclabendazole (TBZ), considering their solubility, bioavailability, and activity.

Materials And Methods: Innovative preparations in solid dispersions (SD) were obtained using the joint mechanical processing of drug substances with polyvinylpyrrolidone (PVP) in an LE-101 roller mill.
