Abstract: The intestinal absorption and antiasthmatic efficacy of poorly water-soluble curcumin (CUR), which has low solubility and permeability, was increased by fabricating solid dispersion granules (SDGs). The SDG containing CUR (SDG-CUR) was prepared by dispersing CUR in excess Cremophor RH40 as a solubilizer and Ryoto sugar ester L-1695 as an absorption enhancer using fluid bed granulation. We evaluated the physicochemical properties such as crystallinity and dissolution, pharmacokinetics, and antiasthmatic efficacy of SDG-CUR. Our results showed that CUR was molecularly dispersed, and the dissolution of SDG-CUR was significantly higher than that of native CUR. In addition, the blood concentration of SDG-CUR in rats was much higher than that of native CUR. Compared to CUR, SDG-CUR showed a 9.1- and 13.1-fold increase in area under the plasma concentration-time curve (AUC) and maximum plasma concentration (Cmax), respectively. Further, SDG-CUR effectively alleviated airway hyperresponsiveness and levels of T-helper 2 cytokines (interleukin-4, interleukin-5, and interleukin-13) in a murine model of asthma. In conclusion, our results suggest that the SDGs could be considered as a potential oral formulation to enhance the absorption and efficacy of CUR.
