    다국어 초록 (Multilingual Abstract) kakao i 다국어 번역

    Solid dispersions of poorly water-soluble drug, itraconazole, were prepared with hydrophilic polymer, poly-N-vinylpyrrolidone (PVP) and organic acid, citric acid (CA), to improve the bioavailability. In order to investigate the correlation between bioavailability and physicochemical properties of the different preparation types, the samples were characterized by scanning electron microscopy, differential scanning calorimeter, Fourier transform infrared spectroscopy and x-ray powder diffraction. The particle sizes of solid dispersions were smaller than those of other preparation types. Also, it can be observed that the crystallinity of ITZ in solid dispersions was much smaller than that of other praparation types. The crystal structure of solid dispersed ITZ with PVP and CA (SITPC) was different that of intact ITZ. The bioavailability of SITPC was higher than that of solid dispersed ITZ with PVP or solid dispersed ITZ with CA. It is concluded that the solid dispersion using the spray-drying method with PVP, hydrophilic polymer, and citric acid, organic acid, may be effective for the improvement of the bioavailability.
