Effect of PEGylated chitosan as multifunctional stabilizer for deacetyl mycoepoxydience nanosuspension design and stability evaluation
چکیده انگلیسی
Here a series of multifunctional stabilizers was designed and used in a nanosuspension stability enhancement study. Methoxypolyethylene glycol (M PEG)-grafted chitosan, accompanied by space steric hindrance, an electrostatic repulsion function, and a solvation effect, is a multifunctional stabilizer. Deacetyl mycoepoxydience (DM) nanosuspension was prepared using the anti-solvent precipitation approach. The effects of the DM and the multifunctional stabilizer concentration, solvent to anti-solvent ratio, crystallization and storage temperature, and ultrasonic time on drug particle formation during the anti-solvent processing were investigated and the nanosuspension stability was studied. The nanosuspension showed dendritic-like nanostructures and a crystalline state in a morphology and crystalline state study. The optimized drug and multifunctional stabilizer concentration range were selected through the response surface optimization method. The most appropriate and stable nanosuspension could be obtained through the optimal parameters. This study demonstrated that M PEG-grafted chitosan (M PEGC) could be used as a multifunctional stabilizer to control particle size and improve nanosuspension stability.
