Title: A Composition for Solubilizing Fenbendazole and Uses Thereof
Inventor: SHIN DAE HWAN
IPC: A61K47/34
Filed: 2020-11-13
Abstract: The present invention relates to a composition for solubilizing fenbendazole and a use thereof, and more specifically, to a solubilization composition with improved solubility in water by encapsulating fenbendazole, which is a poorly water-soluble drug, in a specific polymer to form micelles, and a use of the composition for solubilizing fenbendazole as a pharmaceutical material. The composition for solubilizing a fenbendazole compound according to the present invention can effectively solubilize the fenbendazole compound by using a polymer micelle formed by an association of a polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol graft copolymer (PCL-PVAc-PEG). The fenbendazole compound is a poorly soluble substance and hardly exists in a water layer, and is solubilized by being encapsulated in micelles. In this way, the fenbendazole compound, which is a poorly soluble substance, can be dissolved in the water layer and thus developed as an intravenous injection using water. The intravenous injection can avoid a hepatic first pass effect compared to oral dosage forms, thereby reducing unnecessary drug loss. Compared to the oral dosage forms, the intravenous injection can also increase bioavailability, and thus is expected to provide a high effect even with the same amount of drug as an effective administration method. Thus, the development of such formulation enables effective administration of the fenbendazole compound.
