Abstract

See full text

A nanonization method for cannabidiol (CBD) includes following steps: the CBD is dissolved in a good solvent to obtain a CBD-good solvent solution, the CBD-good solvent solution is added to aqueous solution of a stabilizer to obtain mixed solution, the mixed solution is ultrasonicated followed by removing the good solvent by rotary evaporation from the mixed solution to obtain a nanosized CBD suspension. The stabilizer includes one or more selected from the group consisting of poloxamer, tween, polyoxyethylene alkyl ether, polyvinyl pyrrolidone, hydroxypropyl methyl cellulose and carboxymethyl chitosan. Particle size of the CBD is reduced in the nanonization method for the CBD through the nanonization of insoluble drugs to obtain the nanosized CBD suspension. In the nanosized CBD suspension, nanosized CBD has high solid content. The nanonization method for the CBD achieves solubilization of the CBD.
