| Summary: | 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. The study focuses on two key anthelmintics, praziquantel (PZQ) and fenbendazole (FBZ), employing mechanochemical techniques to enhance their solubility and efficacy. Solid dispersions (SD) of PZQ with polymers and dioctyl sulfosuccine sodium (DSS) and fenbendazole with licorice extract (ES) and DSS were prepared. The helminthicidal activity of these complexes was assessed through helminthological dissections of sheep infected with Schistosoma turkestanicum, moniesiasis, and parabronemosis. In the assessment of supramolecular complex of FBZ (SMCF) at doses ranging from 1.0 to 3.0 mg/kg for the active substance (AS), optimal efficacy was observed with the fenbendazole formulation containing arabinogalactan and polyvinylpyrrolidone at a 3.0 mg/kg dosage. At this concentration, the formulation demonstrated a remarkable 100% efficacy in treating spontaneous monieziosis in sheep, caused by Moniezia expansa (Rudolphi, 1810) and M. benedenii (Moniez, 1879). Furthermore, the SMCF, administered at doses of 1.0, 2.0, and 3.0 mg/kg, exhibited efficacy rates of 42.8%, 85.7%, and 100%, respectively, against the causative agent of parabronemosis (Parabronema skrjabini Rassowska, 1924). Mechanochemical modifications, yielding supramolecular complexes of PZQ and FBZ, present a breakthrough in anthelmintic development. These complexes address solubility issues and significantly reduce required doses, offering a practical solution for combating helminth infections in livestock. The study underscores the potential of supramolecular formulations for revolutionizing helminthiasis management, thereby enhancing the overall health and productivity of livestock.
