Abstract
Ketoconazole (K) is a poorly water-soluble drug that faces significant challenges in achieving therapeutic efficacy. This study aimed to enhance the dissolution rate of ketoconazole by depositing spray-dried ketoconazole (SK) onto the surface of ground trehalose dihydrate (T) using spray drying. Ketoconazole-trehalose surface solid dispersions (SKTs) were prepared in ratios of 1:1 (SK1T1), 1:4 (SK1T4), and 1:10 (SK1T10), and characterized them using particle size analysis, scanning electron microscopy, powder X-ray diffraction, and in vitro dissolution studies. Results showed that the dissolution rates of the dispersions were significantly higher than those of pure ketoconazole, with the 1:10 ratio showing the highest dissolution rate. The improved dissolution was attributed to the formation of a new crystalline phase and better dispersion of ketoconazole particles. These findings suggest that the surface solid dispersion approach could be a valuable method for enhancing the bioavailability of poorly water-soluble drugs. Graphical Abstract: (Figure presented.)
