Abstract

We prepared nanoparticles containing insoluble celecoxib by the method of solid dispersions using a spray dryer to improve solubility of celecoxib. We used PVP K30 and Eudragit EPO as water-soluble carriers for the solid dispersion, and poloxamer 407 as a surfactant. Characterization of celecoxib solid dispersion was performed by scanning electron microscope (SEM), differential scanning calorimetry (DSC), X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). The results of SEM, DSC and XRD demonstrated that celecoxib is amorphous in solid dispersion. The dissolution rate measured in intestinal juice showed that the method of solid dispersion improved celecoxib solubility as compared with a conventional drug (Celebres®). In conclusion, solid dispersion formulation prepared by a spray dryer would improve the solubility of celecoxib in oral administration.
